Next, the control of the camera of this embodiment will be described with reference to a flowchart. The main routine includes a POFF loop corresponding to a standby state and a PON loop in an operating state. That is, each process for controlling the camera of this embodiment is executed from the PON loop. The control process is roughly divided into the following four processes. First, the shutter button 2

Release processing for controlling shooting by full pressing of 6, and then SW operation display for controlling display processing associated with operation of mode button 40, drive button 38, Tv / Av button 30, up / down lever 28, hyper button 52, etc. There is an AE calculation process for controlling a loop and various program calculations, and a learning calculation process for controlling a learning function for learning a photographer's operation. The SW operation display loop is further divided into processing in an exposure mode, such as exposure correction and program shift, and processing in a special function setting mode.

[Main Routine] FIG. 12 is a flowchart showing a main routine for controlling the camera according to the present embodiment. This flowchart is
It starts when the battery is attached to the camera. When the battery is loaded into the camera body 10, first, interrupt processing is prohibited, and initialization processing such as initialization of flags, initialization of RAM / registers, and checksum of ROM is executed (S1201, S1203). Next,
Once in the power hold on state, power is supplied to the hardware of the entire camera, and the data stored in the EEPROM 106 is written into the RAM of the CPU 20 (S1).
205, S1207). When the above process is completed, the process proceeds to a POFF loop, which is repeatedly executed when the main switch of the camera is in the off state.

[Data Format of EEPROM / RAM] FIGS. 58 and 59 are diagrams showing formats of data stored in the EEPROM and data written in the RAM.

[POFF Loop] In the POFF loop, first, the SW operation display loop is called. In the SW operation display loop, the release switch 72, the photometry switch 70, the main switch 11
0, "1" or "0" is set according to the on / off state of the clear switch 76, the up switch 78, the down switch 80, the drive switch 82, the mode switch 84, and the hyper switch 88.
Photometry SW, Main SW, Clear SW, UPSW, DOW
Each flag such as NSW, drive SW, mode SW, HYPSW and various flags set according to the operation of each switch are input to the CPU, and based on these, the external display LCD panel 36 and the internal display LCD panel 62 Is displayed (S1211, S121)
3). Here, when “0” is set in the main SW (that is, when the main button 36 is at the OFF position), only the SW operation display loop is called at a cycle of 128 ms (S1211, S1213), and the power Hold O
The state of the FF is held (S1229, S1231, S123
1233). Even if “1” is set in the main SW (that is, the main button 36 is in the PICT position or in the ON position).
(1) Release switch, (2) Photometry switch, (3) Hyper switch (HYPSW), (4) Up switch (UPSW), (5) Down switch (DOWNSW) Or the PF mode flag is set to “0”, the power hold OFF state is still held, and 128 m
Only the SW operation display loop is called in the cycle of s (S
1217 to S1233, S1211, S1213).
Here, the PF mode flag is set to "1" when the camera is operated in a special function setting mode (PF mode) described later. Therefore, in the PF mode, the process proceeds to RESTART regardless of the state of the operation SW.
If any of the above (1) to (5) is turned on during execution of the POFF loop, the RESTART process of FIG. 13 is executed.

[RESTART] FIGS. 13A and 13B are flowcharts showing the RESTART process. The RESTART processing is performed in the POFF loop shown in FIG. 12 when "1" is set in any one of the above flags (1) to (5) while "1" is set in the main SW, or PF
This is a process executed when "1" is set in the mode flag. In step S1301, the power is turned on, the power is supplied to the entire hardware of the camera, and the power is turned on again.
The data in the EPROM is read and written into the RAM (S1
303). In S1305, the number of repetitions of the PON loop executed thereafter is set in the counter PON timer, and the process proceeds to the PON loop.

“PON Loop” In the PON loop, communication between the camera body 10 and the lens 12 and an external flash (not shown), photometric processing, AE calculation for calculating a Tv / Av value based on a photometric result, and the like are performed. Execute. In addition, it controls the release process. First, in order to determine the repetition period of the PON loop, 1
The 28 ms timer is started (S1311), and the display on the external display LCD panel 36 and the display LCD panel 62 in the viewfinder is controlled by the SW operation display loop (S13).
1313). If "1" is set in the main SW (S1315: main SW = "1"), data communication from the external flash to the camera body and communication between the camera body and the lens are performed (S1317, S131).
9). Next, normal photometric processing is performed (S132).
1) An AE operation is performed based on the photometric data (S
1323). After predetermined data is transmitted from the camera body to the flash based on the result of the AE operation (S1325), a display process including the operation result is performed by a SW operation display loop (S1327). Shutter button 26
Is fully pressed (S1329: Release SW =
In “0”), a release process is performed. If the release switch 72 is in the OFF state (S1329: release SW = “1”), the AF loop is called and 128 ms
Until the timer expires, the AF loop is repeatedly called while monitoring the state of the release SW (S
1329 to S1333). After a lapse of 128 ms, photometry S

State (a state in which “0” is set), and the PF mode flag = “0” (indicating that the mode is not the special function setting mode) is held (S1335 to S1343).
When the PON loop is repeated the number of times set in S1305, the processing shifts to the POFF loop (S1).
345-S1347). On the other hand, in other cases, P
The ON loop will be repeated.

“Release Process” FIG. 14 is a flowchart illustrating the release process. In the release processing, photometry processing (S1401), data communication from the flash to the camera body (S1401)
3) After the AE operation (S1405) described later, data communication from the camera body to the flash based on the AE operation result (S1407), and the SW operation display loop (S1409) are performed, mirror up and aperture control (S141)
A series of exposure operations of 1), exposure processing (S1413), film winding, and mirror down (S1417) are performed. In the camera of the present embodiment, after the exposure processing is completed, a learning operation described later is executed (S1415), and the settings of the photographer are learned. When the release process ends, the process returns to the PON loop shown in FIG.

[Switch Operation Display Loop] FIG. 15 shows an external display L according to the operation of the operation button of the camera.
9 is a flowchart for explaining a SW operation display loop for controlling display on the CD panel 34 and the display LCD panel 62 in the viewfinder. In the SW operation display loop, processing according to the operation of the operation button, such as ISO sensitivity display, switching between the PF setting mode and other shooting modes, is performed and displayed. In S1501, FIG.
As shown in FIG. 1, the state of each switch set according to the operation of the operation button of the camera is read, and each flag (main SW, PF mode flag, mode SW, drive SW,
PFOUTM flag).

In the camera of this embodiment, when the mode button 40 and the drive button 38 are simultaneously pressed in a normal photographing enabled state, first, the ISO sensitivity is displayed on the external display LCD panel 34. The PF setting mode (special function setting mode) is entered. When entering the PF setting mode, the PF mode flag is set to "1"
Is set (described later). In the SW operation display loop, if the main switch is “0”, the external display LCD panel 34 and the finder display panel 62 are turned off, and after performing the PF cancel processing described later, the SW operation display is performed. Returns to the point where the loop was called.

"1" is set in the main switch, and
When the PF setting mode has not been entered, the state of the mode SW and the drive SW is determined. If “0” is set in both the mode SW and the drive SW, the process branches depending on the PFOUTM flag. P
The FOTM flag is set only when the PF setting mode is normally terminated after the PF setting mode has been entered.
“1” is set, and is normally “0”. still,
When returning from the PF setting mode to the normal exposure mode,
The mode button 40 and the drive button 38 are simultaneously pressed for a predetermined time. Mode SW and Drive SW
Are both "0", the PF timer is incremented from zero. When the PF timer is less than 31, the ISO sensitivity is displayed on the external display LCD panel,
At the same time, the remaining time until entering the PF mode is displayed as a graph by the PF timer display process (described later). When the PF timer display processing ends, the process returns to the place where the SW operation display loop was called. In S1513, when the PF timer becomes 31 or more, 1 is set in the PF mode flag indicating entry into the PF mode, and "1" is also set in the PFINM flag. Incidentally, PF timer = 31
Corresponds to a time interval of approximately 2 seconds. If the PF mode flag is set to "1", the process proceeds from S1505 to the PF loop when the next SW operation display loop is called. The PF loop monitors the state of each switch while operating in the PF setting mode. still,
The PF loop will be described later. In this embodiment, the ISO display is displayed only while the mode button 40 and the drive button 38 are simultaneously pressed. I
Control may be performed so that SO display is performed.・

If either the mode SW or the drive SW is turned off while the ISO sensitivity is being displayed, that is, while the remaining time until entering the PF mode is displayed as a graph, the PF timer is cleared and 0 is set. And also
“0” is set to the PFOUTM flag. Note that P
If the drive button 38 and the mode button 40 are kept pressed when the mode is shifted from the F setting mode to the exposure mode, "1" is set in the PFOUTM flag. The processing advances so that the PF setting mode is not reentered. In order to shift to the PF setting mode again, one of the mode button 40 and the drive button 38 is released once and S15
After setting the PFOUTM flag to "0" at 25,
By pressing both buttons simultaneously again, it is possible to shift to the PF setting mode. Thus, immediately after switching from the PF setting mode to the shooting mode, even if the drive button and the mode button are kept pressed, the PF
The operability is improved without switching to the setting mode. During the operation in the normal exposure mode, if at least one of the mode button and the drive button is not pressed, the process related to the PF setting mode is not performed, and the process proceeds to the SW operation display 1 (S1507, S1509, S1507).
1525).

[Switch Operation Display 1] FIGS. 16A, 16B and 16C are flowcharts of SW operation display 1. In the SW operation display 1 process, display of data selected / set by operating the up / down lever 28 is controlled. First, 0 is set to the learning mode flag in S1601. In the present embodiment, “0” (learning permission) is set to the learning prohibition flag in the PF setting mode, and the learning mode (person, landscape, moving object,
Only in the case of “proximity”, “1” is set in the learning mode flag, and learning is performed (described later).
In the U / D loop executed in S1603, various setting / display processes according to the operation of the up / down lever 28 are performed (details will be described later). In the AE mode setting process in S1605, the data set in the U / D loop
Depending on whether the main button 36 is in the PICT position or the ON position, the exposure mode is green, person, landscape, moving object,
It is determined which mode is the proximity, program, auto, or manual mode (details will be described later), and a value corresponding to the exposure mode is set in the variable “AE mode”.

Next, the processing branches according to the exposure mode (S1608 to S1609). In FIG. 16B, S1
Steps 611 to S1621 are processing relating to a program shift described later, and steps S1623 and S1625 are processing relating to exposure correction. When the exposure mode is the green mode or the manual mode, the program shift and the exposure correction are not performed, so that the above steps are not performed. In the case of the auto ゛ mode, only exposure correction is performed, and no program shift is performed. In the case of the program mode, a graph is not displayed, but a program shift is possible, and the processing from S1619 is performed.

When the exposure mode is the portrait, landscape, moving object, or proximity mode, the camera of this embodiment has a function of learning the program shift amount set by the photographer. In this learning function, a patrone is attached to the camera, and
It is valid only when the learning prohibition flag is set to “0” in the PF setting mode. When the above condition is satisfied, the learning mode flag is set to "1" (S1611 to S1615). Next, in the P shift graph display processing, the program shift amount set by the photographer is graphically displayed on the external display LCD panel 34 and the finder display LCD panel 62. The set program shift amount can be canceled by pressing the Tv / Av button 30 alone. S1619
In the example, a program shift canceling process is performed (details will be described later). In S1621, the characters “Tv” and “Av” and the overline 58k on the arc are displayed.
A process of displaying 58m on external display LCD panel 34 is performed.

As described above, in the camera of this embodiment, when the exposure mode is set to person, landscape, moving object, proximity, program, or auto, the exposure correction can be set. When the hyper button 52 is pressed, a graph of the exposure correction is displayed on the external display LCD panel 34 and the viewfinder display LCD panel 62. With the exposure compensation graph displayed,
That is, the amount of correction is set by rotating the up / down lever 28 while pressing the hyper button 52 (S
1623). The set exposure compensation amount can be cleared by pressing the Tv / Av button 30 while the exposure compensation graph is displayed (S1625). The details of the exposure correction display and the exposure correction clear processing will be described later.

When the exposure mode is auto, Tv / A
Switching between shutter priority and aperture priority can be performed by operating the v button 30 (S1627). In the case of the shutter priority, the Tv value can be changed by operating the up / down lever 28. In the case of aperture priority, the Av value can be changed by operating the up / down lever 28. At this time, on the external display LCD panel 34, Tv or Av
Of which, the priority is given to the arc-shaped overline 58k
Or 58m is displayed, and on the internal display panel,
An underline is turned on for the prioritized Tv value or Av value (S1629).

If the exposure mode is manual, the deviation of the manually set Tv / Av value from the calculated proper exposure value is displayed in a graph by the exposure display process (S1631). When the hyper button 52 is pressed alone in the manual mode, an appropriate exposure value calculated according to a program is set. The setting of the Tv / Av value in the manual mode is performed by the up / down lever 28. Which is set by the up / down lever 28 is determined by Tv / Av as in the case of the auto mode.
Switching is performed by the switch 30 (S1633). Also,
As in the case of the auto mode, the external display LCD panel 3
4, the arc-shaped overline 58 k or 58 m is displayed on the Tv or Av that can be changed by the up / down lever 28, and the Tv value or the Av value is lower than the Tv value or the Av value on the display LCD panel in the viewfinder. The line is turned on (S1635). The Tv value and Av value determined as described above are displayed on the external display LCD panel 34 and the viewfinder display LCD panel 62 (S1637), as well as the display of each exposure mode / drive mode, the display of the presence or absence of learning, and others. Various displays determined for each mode are performed (S1641).

[PF Loop] FIG. 17 is a flowchart of the PF loop processing. P
In the F loop processing, a branch is made to a PF loop 1 processing for setting and changing various special functions in the PF setting mode.
Further, after the function setting is completed, a process for returning to the normal exposure mode is controlled.

For setting the special function (PF), in the PF setting mode, a setting item is selected by operating the mode button 40, and data is changed by rotating the up / down button 28. If one minute elapses without performing the above-described special function setting operation during the PF setting mode operation, the PF
The setting mode processing is canceled, and the mode returns to the exposure mode. Therefore, when any one of the mode SW, the UPSW, and the DOWNSW is turned on by the PF end timer, 0 is set in the PF end timer, and when none of the modes is turned on, the clocking is continued. When the mode button 40 and the drive button 38 are simultaneously pressed from the normal exposure mode to proceed to the PF loop,
Since “1” is set in the PFINM flag in S1527 in FIG. 15, the process proceeds from S1715 in FIG. 17 to the PF display process. Since the PFINM flag is set to “0” in this PF display processing, the PF display processing
This is executed only when the process proceeds to the setting process.
Alternatively, when the drive button 38 is released, it is not executed during the PF setting mode operation.

As described above, the setting items are changed by the PF loop 1 when the mode switch is ON (that is, when the mode switch is set to “0”). "0" for both mode SW and drive SW
When the state in which is set continues for a predetermined time (2 seconds in this embodiment), the process proceeds to the PF setting end process, and the set special function is determined (written in the EEPROM 106).
The count and display of the time until the process proceeds to the PF setting end process are shown in S1513, S1515, and S1519 in FIG.
(S1717, S1719, S172)
1).

[PF Display Processing] FIG. 18 is a flowchart showing the PF display processing that is executed when the process proceeds from the normal exposure mode to the PF setting mode. The PF display processing is executed when the mode button 40 and the drive button 38 are simultaneously pressed in the operation state in the normal exposure mode to display the ISO sensitivity, and after a predetermined time has elapsed, the mode is shifted to the PF setting mode.

In FIG. 15, when the count value of the PF timer becomes equal to or more than the predetermined value (31) (that is, when the mode button 40 and the drive button 38 are continuously pressed for 2 seconds), the program goes to S15.
At 27, "1" is set to the PF mode flag and the PFINM flag. Then, when the SW operation display loop of FIG. 15 is executed next while the mode button 40 and the drive button 38 are kept pressed, the process proceeds to the PF loop in S1505, and further, the PF loop of FIG. The process proceeds from the loop S1715 to the PF display process in FIG.

In the PF display process, [PF] is first displayed to indicate that the mode has shifted to the PF setting mode, and "1" is set in a mode SWM flag described later. At this time, if the Tv / Av button 30 is not pressed (S1803: clear SW = "1"), the process returns to the place where the SW operation display loop branched to the PF display process was called.

In the camera according to the present embodiment, when the Tv / Av button 30 is pressed while the mode button 40 and the drive button 38 are pressed and [PF] is displayed on the external display LCD panel 34, the set special All functions are cleared and set to default values. S1805-S
Reference numeral 1815 denotes a process for that. If the Tv / Av button 30 is pressed (S1803: clear SW = "0"),
“0” is set to the mode SWM flag. S180
The PF timer is set to 0 only when the processing after 5 is performed for the first time.
In step S1807, the process branches according to the PFINM2 flag. That is, only the first
INM2 = “0”, and from the second time on, PFINM2 =
Since it is "1", the PF timer is not reset. The processing of S1811 to S1815 is performed in S1515 to S1519 of FIG. 15 or S171 of FIG.
In the same process as 7 to S1721, the remaining time until the process proceeds to the PF all clear process for clearing the settings is displayed in a graph. When a predetermined time has elapsed, that is, when the count value of the PF timer exceeds 31, the process proceeds to the PF all clear process, and the set value is returned to the default value.

[PF Loop 1] FIGS. 19A and 19B are flowcharts showing the processing of the PF loop 1 for controlling the setting of the special function and the display of the setting contents. In the camera according to the present embodiment, if the setting operation is not performed for one minute or more during the operation in the PF setting mode, all the setting contents during the operation in the PF setting mode are canceled, and immediately before shifting to the PF setting mode. Is kept as it is. Therefore, first, S1
At 901, it is determined whether the PF end timer is one minute or longer. The PF end timer corresponds to S1701 to S1 in FIG.
As indicated by reference numeral 707, the mode switches SW, U
It is reset every time one of PSW and DOWNSW is determined to be in the ON state. That is, each time the mode button 40 or the up / down lever 28 is operated, 0 is set in the PF end timer. Therefore, if the state in which neither the mode button 40 nor the up / down lever 28 is operated continues for one minute or more, the processing proceeds from S1901 to the PF cancel processing.

On the other hand, during the operation in the PF setting mode, the process proceeds from S1901 to S1903. First, S190
At 3, the PFINM flag is set to "0" and the PF timer is set to the count value 0. When shifting from the exposure mode to the PF setting mode, the PFINM flag is set to S1 in FIG.
At 527, it is set to 1, and at S1715 in FIG.
It is responsible for branching to display processing. If the mode button 40 and the drive button 38 remain depressed even after shifting to the PF setting mode, the PFINM flag is "1", so that the processing always proceeds from S1715 to the PF display processing. Also, once the mode button 40 or the drive button 38 is released, the PF display processing is no longer performed, and
The process proceeds from S5 to S1717, and the PF setting end process becomes executable.

In order to shift from the PF setting mode to the exposure mode, the mode button 40 and the drive button 38 must be pressed simultaneously for a predetermined time. The PF timer counts this time.
As can be seen from 1713, once the mode button 40 or the drive button 38 is released, 0 is set in the PF timer. Next, S1905 and S1907
Then, it is determined whether the up / down lever 28 is operated. When the up / down lever 28 is operated to the up side, "1" is set to the UPM flag in a U / D loop described later. When operated down, D
"1" is set to the OWNM flag.

If the up / down lever 28 is not operated, the setting items of the special function are changed by operating the mode button 40 in S1909. In the camera of this embodiment, special functions that can be changed include (A) ISO sensitivity, (B) learning change level, (C) presence or absence of AF in-focus sound, (D) presence of learning, and (E) learning of Clear, 5 items are provided. In the PF setting mode, these five items are sequentially (A) each time the mode button 40 is pressed,
(B), (C), (D), and (E) are selected, and when the mode button 40 is pressed again while (E) is selected, (A) is selected. .

Next, in step S1911, the above-described mode SWM
The U / D loop is executed only when the flag is 0. In the U / D loop, the data of the setting items is changed by operating the up / down lever 28. In the camera of this embodiment, the mode button 40 and the up / down lever 2
The setting item or data is changed only when only one of the buttons 8 is operated. For this reason, it is determined whether or not to call the U / D loop in S1913 based on the mode SWM flag. Mode SW
The M flag is changed in the PF mode UP process in S1909 (details will be described later). S1915 to S19
At 27, the set items and their data are displayed. When the setting item is (A) above, the film IS
O sensitivity is displayed. When the setting item is (B), a numerical value from 0 to 4 corresponding to the combination of the selected learning level and the number of times is displayed. If the setting item is (C), “0” (the electronic buzzer 108
) Or “1” (electronic buzzer 108 when focused)
In addition to the display of “Do not sound”, the buzzer sounds periodically when “0” is selected, and the buzzer does not sound when “1” is selected.
The setting contents can be confirmed aurally. In the case of the setting item (D), “0” (learn), “1”
In addition to the numerical display of (not learned), the setting contents can be visually confirmed easily by turning on / off the learning mark. In the case of the setting item (E), a picture representing the selected exposure mode and a character "CL" indicating that clear has been set are displayed. PF loop 1
Is a branch from the SW display operation processing loop, and upon completion of the above processing, returns to the place where the SW display operation processing loop was called.

“PF Mode UP” FIG. 19C shows the PF called in S1909 of FIG. 19A.
It is a flowchart which shows a mode UP process. This process is called when the up / down lever 28 is not operated. When the PF mode UP process is executed,
First, it is determined whether or not the mode button 40 has been operated (S1931). When "1" is set in the mode SW, "0" is set in the mode SWM flag. As a result, S1911 to S191 of FIG.
The process proceeds to 3, and data can be changed by the up / down lever 28.

When "0" is set in the mode SW, the PF mode is incremented only when "0" is set in the mode SWM flag (S19).
37), setting items are changed. PF mode is 0-4
If the PF mode becomes 5 or more, 0 is set (S1939). Once the PF mode is incremented, "1" is set to the mode SWM flag (S1943). Thus, the mode button 4
After pressing 0 to change the setting item,
In a state where 0 is kept pressed, the processing for changing the setting item is not executed in S1935. That is, once the mode button 40
The control is such that the setting items do not change unless the key is released, and the operability is excellent. When the processing is completed, P
Return to the location where the F-mode UP processing was called.

“PF All Clear / PF Setting End Process” FIG. 20 is a flowchart showing the PF all clear process and the PF setting end process. The PF all clear processing is performed in S1811 in the PF display processing of FIG.
It is executed when the count value of the PF timer becomes 31 or more. That is, the mode button 40 and the drive button 38 are simultaneously pressed and held for a predetermined time to enter the PF setting mode, and the external display LCD
When [PF] is displayed on the panel 34, the operation is executed when the Tv / Av button 30 is further pressed for a predetermined time (2 seconds). In the PF all clear process, all data whose setting can be changed in the PF setting mode is returned to the initial value (S2001).

When the camera is loaded with a DX film, the ISO sensitivity read from the DX code of the film is set as an initial value. Is set. As the learning change level, the change level = 0, the number of times 1 = 3, and the number of times 2 = 3 are set as initial values. The initial setting is to sound the electronic buzzer 108 for the in-focus sound, and the initial setting is to perform learning for the presence or absence of learning. Regarding the learning clear flag, “1” is set to all the learning clear flags corresponding to each of the four exposure modes of person, landscape, moving object, and proximity in order to clear learning.

The above setting is performed on the RAM, and then S
In the PF setting end processing after 2011, the data on the RAM is written into the EEPROM 106. Regardless of the exposure mode, ISO sensitivity, learning change level, presence / absence of in-focus sound, and presence / absence of learning are set in the PF setting mode.
The changed data on the RAM directly corresponds to the data on the EEPROM. Therefore, the data in the RAM is directly written into the EEPROM (S2011). On the other hand, in learning clear, only the value of the learning clear flag is changed for each mode.
Rewrite the contents of T (X) and STDYCNT (X),
Further, it is written in the EEPROM (S201
3-S2019). When the above process ends, the process advances to S2111 in FIG. 21 to reset various flags and counters. Here, "1" is set to the flag PFOUTM flag indicating that the mode has shifted from the PF setting mode to the exposure mode. PF all clear processing is S
This is a branch from the W operation display loop. Therefore, when the PF all clear processing is completed, the process returns to the place where the SW operation display loop is called.

“PF Cancellation Process” FIG. 21 is a flowchart illustrating the PF cancellation process. In the camera of the present embodiment, the setting of the special function is performed in the PF setting mode, and by pressing the mode button 40 and the drive button 38 simultaneously for a predetermined time, the set contents are written into the EEPROM (see FIG. 17 and FIG. 17). 20), the PF setting mode ends. But,
When the PF setting mode is interrupted by any other method (that is, when the main button 36 is set to the OFF position during operation in the PF setting mode, or when the setting operation is not performed for one minute or more in the PF setting mode) Is changed in the PF setting mode and is not written in the EEPROM 108, but is canceled. In particular, if the setting operation is not performed for 1 minute or more in the PF setting mode, the P
Shift from the F setting mode to the exposure mode, and
08 is written to the RAM.
When the cancel process is executed, “0” is set to the learning clear flag (X) of each mode so that the learning is not cleared in any mode (S2).
101). The PF cancel process is a branch from the SW operation display loop. Therefore, when this PF cancel processing ends, the process returns to the place where the SW operation display loop was called.

“U / D Loop Processing” FIG. 22 is a flowchart showing a U / D loop for changing data by operating the up / down lever 28. When the down switch 80 is turned on (when DOWNSW is set to “1”), DOWN
“1” is set to the M flag (DOWN memory flag), and “0” is set to the UPM (memory) flag. On the other hand, when "1" is set in the UPSW, "1" is set in the UP memory flag, and "0" is set in the DOWN memory flag (details will be described later). Therefore, when the up switch 78 is on, the UP loop flag is set to "1" and the UP loop processing is performed.
The DOWN loop processing is not performed (S2201 to S22
05). On the other hand, when the down switch 80 is on, the UP loop flag is set to “0” and the DO loop flag is set to “0”.
Only WN loop processing is performed (S2207 to S221)
1). When the above processing ends, the processing returns to the place where the U / D loop is called.

[UP Loop] FIG. 23 is a diagram showing an UP loop called in the U / D loop (FIG. 22).
It is a flowchart which shows a process of a loop. When the up switch 78 is off (S2301: UPSW =
In "1"), the data is not changed, "0" is set in the UP memory flag indicating that the up switch 78 is off (S2303), and the process returns to the U / D loop. When the up switch 78 is on (S2301: U
(PSW = "0"), and it is determined whether or not the up switch 78 was on when the UP loop was called last time (S).
2305) If it is also determined that the previous time is ON (UP memory flag = “1”), the process proceeds to the U / D timer loop. The U / D loop is approximately 64 ms (2 in 128 ms).
Therefore, if the data is changed only by the state of the up switch 78 at the time when the UP loop is called, for example, when the up switch 78 is kept on, If the user holds the state while operating the up / down lever 28 in the up direction, the data is changed in a very short time. In order to prevent this, when the up switch 78 or the down switch 80 is continuously turned on, the U / D timer loop is used to extend the cycle by software. When the UP memory flag is “0”,
The data is changed by the data U / D processing, and the UP memory flag indicating that the up switch 78 is on is set to 1, and the DOWN memory flag indicating that the down switch 80 is off is set to "0" at the same time. U /
The count value of the U / D timer used in the D timer loop is set to 0
(S2305 to S2309).

“DOWN Loop Processing” FIG. 24 is a flowchart showing a DOWN loop. In S2401 to S2409, the down switch 80
23 is performed in substantially the same manner as in FIG.

“U / D Timer Loop Processing” S2411 to S2417 represent processing of the U / D timer loop. In the U / D timer loop, the value is incremented each time this process is executed (S2417).
When the count value of the / D timer becomes 8 or more (S241
1), the data of the special function is changed (S241)
3). That is, if this process is performed eight times while the up / down lever 28 is being operated, the data is changed in accordance with the operation direction of the up / down lever 28.
When the data is changed, the U / D timer is reset and the count value is set to 0 (S241).
5).

“Data U / D Process” FIG. 25 is a flowchart of a data U / D process for executing data change in accordance with the operation of the up / down lever 28. During operation in the PF setting mode (S15
01: PF mode flag = “1”), PF data U / D
The processing branches to the up / down lever 28 and the mode button 4
In combination with 0, the change / setting of the special function is executed. If the PF mode flag is "0", the process branches depending on the operation button pressed in combination with the up / down lever 28. When the up / down lever 28 is operated while pressing the mode button 40, the exposure mode is changed (S2503, S2505). When the up / down lever 28 is operated while pressing the drive button 38, the shooting mode is changed (S250).
7, S2509). When operating the up / down lever 28 while pressing the hyper button 52, exposure correction is performed (S2511, S2513). When only the up / down button 28 is simply operated, (1) if the shooting mode is any of person, landscape, moving object, proximity, and program, a program shift is executed (S2517, S2519); 2) If the shooting mode is auto or manual, the Tv value or the Av value is changed (S2521, S252).
2523, S2524). The setting of the Av value or the Tv value is switched by operating the Tv / Av button 30. After the above processing is performed, the data U /

0) is set. When the setting item is the learning change level, the variable corresponding to the combination of the change level and the number of shutters is set to any one of 0 to 4 by operating the up / down lever 28. Here, one stage of the change level is approximately O.D. This corresponds to a program shift of 5 Ev, and the program shift amount actually set by the photographer is:
If the change level is equal to or higher than the selected change level, learning is performed when the number of exposures indicated by the number 1 is performed, and if the set program shift amount is less than the selected change level, the number 2 is set. Learning is performed when the number of exposures indicated by is performed (S2607). If the setting item is the presence or absence of the AF focusing ON, the focusing ON prohibition flag is toggled between “0” and “1” by operating the up / down lever 28 (S2609). If the setting item indicates whether learning is prohibited, the learning prohibition flag is toggled between “0” and “1” by operating the up / down lever 28 (S2611). When the setting item learning clear is set, a picture indicating the shooting mode is displayed on the external display LCD panel 34, and by operating the up / down lever 28, the learning clear mode is set to one of four modes.
One or all four are selected, and the clear setting is performed by pressing the Tv / Av button 30 (S2613).

“P shift U / D processing” FIG. 27 shows a P shift U / D for setting a program shift.
It is a flowchart of D processing. In the camera of this embodiment, when the exposure mode is the green mode, the program shift is not performed.
The process after 03 is not performed (S2701: P shift inhibition flag = "1"). When the operation direction of the up / down lever 28 is the forward direction, only when the Tv value does not exceed the maximum value and the Av value does not reach the minimum value (S27).
05: TvMAX = "0", S2707: AvMIN =
“0”), the shift is possible. When the direction bit of the P shift stored in the RAM is negative, the value is reduced by 0.5 until the P shift amount becomes zero. When the P shift amount becomes 0, the direction bit is changed to positive (S2717 to S27).
21). When the direction bit is positive, the P shift amount is set to 0.5 unless the P shift amount reaches the maximum value of 154/8 or more.
Is added (S2713, S2715). When the operation direction of the up / down lever 28 is negative, the shift can be performed only when the Tv value is larger than the minimum value and the Av value does not exceed the maximum value. When the P shift direction bit on the RAM is positive, the P shift amount is reduced by 0.5. However, if the P shift amount becomes negative as a result, the RAM
Since the upper data is represented by a binary number, data processing is performed so that the data is represented by negative direction bits and the absolute value of the shift amount (S2729 to S2733). If the direction bit is negative, as long as the P shift amount does not exceed the maximum value,
0.5 is added to the P shift amount (S2735, S273)

“PF Timer Display” FIG. 32 shows a PF timer display process for displaying the remaining time when the drive button 38 and the mode button 40 are simultaneously pressed to enter the PF setting mode and exit from the PF setting mode. It is a flowchart showing. Switching between the PF setting mode and the exposure mode is performed when the count value of the PF timer becomes equal to or more than a predetermined value (31) (FIGS. 15 and 18). For this reason, the PF timer display data shown in FIG. 37 is selected based on the numerical value of the PF timer and written into the display RAM, so that the graph display corresponding to the remaining time is performed on the external display LCD panel 34. (S3201, S3203).

“AE Mode U / D Process” FIG. 34 is a flowchart of the AE mode U / D process in which the up / down lever 28 selects an exposure mode. In S3401, the process is divided depending on the direction in which the data is changed, that is, according to the operation of the up / down lever 28. In step S3403, the exposure mode is divided into a picture mode (PICT mode) and a full specification mode (FULL mode) depending on whether the main button 36 is at the PICT position or the ON position. The exposure mode is R
On the AM, as shown in FIG. 33, this is set by setting one digit of one of the 8-bit data to 1 and setting the other to 0. When the 8-bit data corresponding to the exposure mode is represented as an exposure mode [8-bit data], in the PICT mode, it is expressed as a green mode [00000001], a moving object mode [00001000], and in the FULL mode, Expressed as in auto mode [00000010]. When the above 8-bit data is represented by a decimal number and expressed as an exposure mode (decimal number), it can be represented as a green mode (1), a moving object mode (8), an auto mode (2), or the like. As shown in FIG. 33, for example, in the PICT mode, when shifting left from the green mode [00000001], a person mode [00000010], a landscape mode [0000001], a moving object mode [00001000], and a close mode [00010000] are obtained. In this embodiment, since the exposure mode set in the PICT mode is of five types, the maximum value of the 8-bit data is [00010000], and S3405 in FIG.
When the value of the PICT mode becomes 16 or more, there is no exposure mode corresponding to the data shifted leftward.

In a normal display, a display including scales and dots is not performed. However, once an exposure correction value is set, the exposure correction amount is graphically displayed in a normal display state. Incidentally, even in the exposure correction in the program mode, the exposure correction value can be set beyond the display range of the graph as in the case described above, and in this case, a black circle blinks at the end point of the graph. The blinking display of the black circle is performed even when the finger is released from the hyper button 52 and a normal display state is set. Also in the program mode, the program shift is possible. When the program is shifted, an overline is displayed in the Tv / Av display portion of the external display LCD panel 34, and the Tv value of the viewfinder display LCD panel 62 is displayed. An underline is added to the Av value (when the shift amount is 0, the overline / underline is not displayed).

In the above description, Tv or Av is indicated by being displayed with an arc-shaped overline, and the display LCD in the finder is displayed.
On the panel 62, the Tv value or the Av value is shown with an underline. The setting as to which of the Tv value and the Av value can be changed is switched by operating the Tv / Av button 30.

The exposure correction is the same as in the above-described program mode. In the exposure correction in the auto mode, the exposure correction value can be set beyond the display range of the graph as in the case described above. In this case, a black circle blinks at the end point of the graph. The blinking display of the black circle is performed even when the finger is released from the hyper button 52 and a normal display state is set.

“Graph Display in Manual Mode” FIGS. 82A, 82B, 83A, 83B, 84A,
FIG. 84B shows a case where the exposure mode is the manual mode.
Using the up / down lever 28, a display when setting the Tv value (FIGS. 82A and 82B), a display when setting the Av value (FIGS. 83A and 83B), and a display when the proper exposure is set (FIGS. 83A and 83B). 84A and 84B).

In the manual mode, if the Tv value can be changed by the up / down lever 28, the Tv display on the external display LCD panel 34 is overlined with an arc, and the Tv value is displayed in the viewfinder. Display LCD

If the range is exceeded, as shown in FIG. 83C and FIG. 83D, the "-" mark is blinked to indicate that the image is underexposed beyond the range (see FIG. 83C and FIG. 83D). A radial line around the "-" mark indicates that the "-" mark is blinking.) In the case of overexposure, similarly, the "+" mark Blinks.

FIGS. 84A and 84B are diagrams showing a case where the manually set exposure value and the calculated exposure value match. To match the manual setting to the calculated exposure,
The set value may be changed by operating the up / down lever 28 to reduce the number of displayed dots. In the camera of the present embodiment, in addition to this, an appropriate exposure value obtained by calculation is set by pressing the hyper button 52 in the manual mode.

[AE Calculation] Next, the processing by the AE (auto exposure mode) calculation subroutine called in S1319 in “RESTART” shown in FIGS. 13A and 13B and S1415 in “release processing” shown in FIG. 41A, 41B,
This will be described with reference to the flowcharts shown in 41C and 41D.

In this embodiment, as the exposure mode, the main button 36 is switched to the PICT position and the picto switch 11
It has a green mode, a person mode, a landscape mode, a moving object mode, and a proximity mode that can be changed when 0b is turned on, and is set when the main button 36 is switched to the ON position and the on switch 110a is turned on. Normal program mode (normal program automatic exposure mode that automatically sets shutter speed and aperture value based on photometric results), auto mode (automatic aperture setting based on manually set shutter speed and photometric results) The shutter speed priority automatic exposure mode of the lens auto, the aperture priority automatic exposure mode for automatically setting the shutter speed from the manually set aperture value and the photometric result, and the manual exposure mode (not shown). Manual aperture priority automatic exposure mode, manual exposure mode, and It has a lube exposure mode.

In the AE processing, first, the body side CPU
After the RAM 20 is initialized and various flags related to photometry and the like are initialized, a lens correction calculation subroutine is called (S4101 to 4105). In this lens correction calculation subroutine, “R” shown in FIG.
In “lens communication” during the processing of “ESTART”, lens correction calculation processing is executed based on various lens data corresponding to the type of the photographic lens input from the lens body side CPU 20 (FIG. 11).

Next, the subject brightness data output from the A / D conversion circuit 98 from each of the divided photometric sensors (light receiving elements 94) is converted into a calculation subject brightness B suitable for calculation.
v, and further calculates the subject brightness Bv for calculation and S
The light quantity value Lv 'for each sensor is obtained from the lens correction value calculated in 4105, and the light quantity value Lv for each sensor is obtained.
From v ′, one light amount value Lv ′ suitable for the subject is calculated based on the divided photometry algorithm (S4107 to S4107).
S4111).

Then, the light amount value Lv is obtained based on the calculation film sensitivity Sv and the calculation exposure correction value Xv which have been converted in advance so as to be suitable for calculation, and the value corresponding to the currently set AE mode (number) is determined by X. (S411
3, S4115).

In S4117, coefficients a, b, TvL1 and the like corresponding to each AE mode put in X are set. These coefficients a, b, TvL1, etc.
OM is set and input in advance.
Read by AM.

In the "person mode (the outline of the program line is shown in FIG. 48A)" branching at X = 1, 2/8 is inserted into the coefficient a, which is the slope of the program line, and 56 /
Insert 8. Further, the camera shake limit Tvf is inserted into the first Tv boundary TvL1, and the photographing optimum A is set to the first Av boundary AvL1.
The v value Avf is inserted, the minimum aperture value AvMIN is inserted into the second Av boundary AvL2, and the program operation subroutine is called in S4143.

In the “landscape mode” (the outline of the program line is shown in FIG. 49A) which branches at X = 2, the coefficient a is set to 2
/ 8, and the landscape coefficient b is inserted into the coefficient b. The landscape coefficient b is obtained by (6/8) × Tvf− (2/8) × (AvMIN + 1). Further, the minimum shutter speed TvMIN is inserted into the first Tv boundary TvL1, and the first Av boundary AvL1 is set.
Into the second Av boundary Av.
The minimum aperture value AvMIN is put in L2, and the program calculation subroutine is called in S4143.

In the “moving object mode” (the outline of the program line is shown in FIG. 50A) where X = 3, the coefficient a is 2
/ 8, and 56/8 into the coefficient b. Further, the camera shake limit Tvf + 1 is inserted into the first Tv boundary TvL1, and the minimum aperture value AvMIN + 1 is added to the first Av boundary AvL1.
And the minimum aperture value AvMIN is set at the second Av boundary AvL2.
Is entered, and the program operation subroutine is called in S4143.

In the “proximity mode” (the outline of the program line is shown in FIG. 51A) where X = 4, the coefficient a is set to 2
/ 8, and 56/8 into the coefficient b. Further, the camera shake limit Tvf is inserted into the first Tv boundary TvL1, Av6 (F = 8) is inserted into the first Av boundary AvL1, and the minimum aperture value AvMIN +1 is inserted into the second Av boundary AvL2.
Is entered, and the program operation subroutine is called in S4143.

In the program calculation subroutine called in S4143, the control Tv and the control Av actually used in the control are calculated based on the Tv value and the Av value set for each mode, which will be described in detail later.

On the other hand, when branching to the "green mode" with X = 1, the program shift inhibition flag is set to "1", and the program line is inhibited so as not to be shifted. Then, the normal program subroutine is called (S4135, S4137), and in this mode, the control Tv and the control Av actually used in the control are obtained.

When branching to the "normal program mode" at X = 5, the normal program subroutine is called without setting the program shift prohibition flag to "1" (S4137).

Further, when branching to "AUTO mode" at X = 6, the AUTO operation subroutine is called (S4139), and when branching to "manual mode" at X = 7, the manual operation subroutine is called (S4139). S4141).

Further, it is determined whether or not the control Tv and the control Av obtained in the mode selected in S4117 are values usable for control by the called CHK. Check by the TvAv subroutine, and if it exceeds the controllable value, it is converted to its maximum or minimum value (S4145). And CHK The number of EE pulses is obtained based on the Tv value and the Av value finally determined by the TvAv subroutine, and further data such as whether or not to emit light to the external flash, how much light is to be emitted, and whether or not it is a rear curtain sync. Send (S
4147, S4149). The EE pulse is a pulse used to stop the aperture corresponding to the aperture value Av for control. Thereafter, in S4151, a quench signal is output at the time of flash photography to set TTL data for stopping flash emission, and the routine returns.

The normal program subroutine shown in S4137 of FIG. 41C will be described with reference to the flowchart shown in FIG. 52A. A program diagram described in this subroutine is shown in, for example, FIG. 52B, and the features are as follows. Camera shake limit Tvf (= TvL1)
Is set. A program line relating to a landscape mode that emphasizes the depth of field (see FIG. 49B) and a program line relating to a moving object mode that emphasizes the shutter speed (see FIG. 50)
B)). When the camera shake limit Tvf (= TvL1) is exceeded, at least one step or more of program shift is enabled.

In the figure, when f = 80 mm and f = 2
Since a camera shake easily occurs near the camera shake limit Tvf (= TvL1) at 8 mm, a low Ev that satisfies Tv <Tvf
In the range, the shutter speed is fixed at the camera shake limit Tvf and the aperture is opened to the minimum aperture value, and when the aperture reaches the open value, the shutter speed is reduced while the aperture is kept open. At this time, the camera shake limit Tvf (= TvL1)
Is assigned to the variable TvL1 and processed.

In the normal program subroutine, first, the fv operation subroutine shown in FIG. 42A is called, and the conversion focal length fv obtained by converting the focal length f in accordance with the apex value by fv = log (focal length f) / log2. Ask for.

Subsequently, in S5203, Tv = (3/8) × light amount Lv + normal coefficient b normal coefficient b = (5/8) Tvf- (3/8) (Av
MIN + 1) to calculate the operation Tv. This calculation formula is, for example, as shown in FIG.
In the program diagram of B, the program line is moved in the shutter axis direction along with the change of the normal coefficient b while the inclination is fixed.

Then, it is checked whether or not the calculation Tv obtained in S5203 is larger than the maximum shutter speed TvMAX. If it is higher, the maximum shutter speed TvMAX is entered as a calculation Tv in the RAM of the body side CPU 20, and the shutter speed to be actually set is set. Is faster, but to show that the maximum shutter speed TvMAX has been added to the calculation Tv,
"1" is set to the Tv over flag (S520).

Further, the CAL shown in FIG. The Av subroutine was called to change the operation Tv.
(S5223), and obtain an appropriate operation Av corresponding to
Exit to 5215. In S5205, the operation Tv
Is smaller than or equal to the maximum shutter speed TvMAX, the calculation Tv is compared with the camera shake limit Tvf. If the calculation Tv is smaller than the camera shake limit Tvf, the camera shake limit Tvf is calculated.
v in RAM (S5207, S5225),
The process proceeds to S5209. If it is determined in step S5207 that the calculation Tv is larger than the camera shake limit Tvf, the process advances to step S5209.

In step S5209, the CAL shown in FIG. The Av subroutine is called, an appropriate operation Av corresponding to the operation Tv set here is obtained, and the flow advances to S5211. S
At 5211, the Av over flag is checked, and if "1" is set to this Av over flag, CA
L Since the Tv subroutine is called to change the operation Av, an appropriate operation Tv corresponding to the operation Av is obtained (S5227), and the process goes to S5215. If “0” is set in the Av over flag, the process proceeds to S521.
Proceed to 3 to check for an Av under flag. Av
CA when the under flag is set to "1"
L By calling the Tv subroutine, an appropriate operation Tv corresponding to the operation Av is determined according to the change of the operation Av (S5227), and the process exits to S5215.

In step S5215, a normal P shift operation subroutine shown in FIG. 46 is called to check for a program shift. That is, S46
At 02, the program shift amount set by the photographer with the up / down lever 28 is entered as the total program shift amount, and at S4604, the P shift direction bit set according to the program shift direction is set to all P shift directions.
Inserted as shift direction bits (S4602, S460
4) The process advances to S4603 to check the P shift prohibition flag. In this embodiment, since no program shift is performed in the green mode, FIGS. 41A, 41B, 41
When the green mode is selected by X = 0 during the AE operation of C and 41D, "1" is set in the P shift prohibition flag, and therefore, the flow returns to S4603 as no program shift. In the normal program (P) mode, the program shift is performed.
S4135 when this mode is selected according to S = 5
And does not set the P shift inhibit flag to "1". Therefore, it is checked that there is a program shift, and the process proceeds to the previous step without returning in S4603.

At S5217, the calculated operation T
v is converted into a value actually used in the control, and is stored in the RAM of the body-side CPU 20 as the control Tv. The calculated operation Av is converted into a value actually used in the control, and is stored in the RAM as the control Av. I do.

Next, the AU shown in S4139 of FIG.
The TO calculation subroutine will be described with reference to the flowchart shown in FIG. First, in S5301, FIG.
Check the TvAv mode flag to be set in S2521 of the data U / D subroutine of
If “1” is set in the v-mode flag, it is determined that aperture priority has been selected, and the flow advances to S5311. If “0” is set, shutter speed priority has been selected, and the flow advances to S5303.

When the shutter speed is prioritized, the manually set Tv is set to the control Tv actually used in the control (S5303). Then, the setting Tv is converted into a value for calculation, and the converted value is input into the calculation Tv to calculate CAL. Call an Av subroutine, calculate an appropriate operation Av corresponding to the operation Tv,
Further, the calculation Av is put into the control Av (S5305 to S5305).
5309), and return. Also, when the aperture priority is given, the setting Av is put into the control Av (S5311), and the setting Av is put into the calculation Av and the CAL is set. Call the Tv subroutine,
An appropriate calculation Tv corresponding to the calculation Av is calculated, and this calculation Tv is entered in the control Tv (S5313 to S5317),
To return.

The manual subroutine shown in S4141 of FIG. 41C will be described with reference to the flowchart shown in FIG. First, in S5401, the T to be set in S2521 of the data U / D subroutine of FIG.
The vAv mode flag is checked, and if "1" is set in the TvAv mode flag, it means that the aperture value can be set by the up / down lever 28 and S5.
Proceed to 419. If "0" is set, up /
Since the shutter speed can be set by the down lever 28, the flow advances to step S5403.

At the time of setting the shutter speed, a setting Tv set by a 1/2 series value processed in steps of 1/2.
Is set in the control Tv, and the setting Av set by the similar 1/2 sequence value is set in the control Av (S5403, S540
5). Here, the on / off state of the hyper (exposure correction) switch 52 is checked. If the hyper switch 52 is not turned on, the process returns with the 1/2 sequence value.
Therefore, in this case, the photographing is performed by the controls Tv and Av based on the values processed in steps of マ ニ ュ ア ル that are manually set.

On the other hand, if the hyper switch 88 is turned on to obtain an appropriate exposure value based on the photometric value,
Is converted into an operation Tv processed in steps of 1/8, and the CAL The Av subroutine is called to find an appropriate operation Av corresponding to the operation Tv, and the operation Av processed in 1/8 step is put into the control Av actually used in the control (S5409 to S54).
13). As described above, in the manual exposure mode, when the release is performed while the hyper switch 88 is turned on by pressing the hyper button 52, the exposure can be performed based on the value calculated by the body side CPU 20 in 1/8 steps with high accuracy. it can.

Further, the operation Av is put into the setting Av, and this is set to 1
Since the process is divided into two series (S5415 to S5417) and the process returns, the subsequent Av value is manually increased / decreased by a 1/2 series value.

The 1/2 series processing is performed in steps of マ ニ ュ ア ル at the time of manual calculation, whereas processing is performed in steps of ８ at the time of automatic calculation. Is smaller than the step of the apex value that can be set manually, so that the calculated apex value is rounded to half the step of the apex value that can be set manually.

At the time of manual aperture setting, a setting A set by a 1/2 series value processed in steps of 1/2.
v is put into the control Av, and the setting Tv set by the similar 1/2 sequence value is put into the control Tv (S5419, S542)
1). Here, the on / off state of the hyper switch 52 is checked, and if the hyper switch 88 is not turned on, the process returns with the 系列 sequence value. Therefore, in this case, the photographing is performed by the control Av and the control Tv based on the values processed in steps of マ ニ ュ ア ル, which are manually set.

On the other hand, when the hyper switch 88 is turned on, the setting Av of the 系列 series value is converted into an operation Tv processed in steps of ８, and the CAL is calculated. Tv
A subroutine is called to find an appropriate operation Tv corresponding to the operation Av, and the operation T

25-S5429). As described above, in the manual exposure mode, the hyper switch 52 is pressed and the hyper switch 88 is pressed.
1/8 with high accuracy when releasing while turning on
In each step, the exposure can be performed based on the value calculated by the body-side CPU 20.

The operation Tv is put in the set Tv, and this is set to 1
Since the processing is returned after performing the 系列 series processing (S5431 to S5433), the subsequent Av value is manually increased or decreased by 系列 series value.

[Program Operation] Next, the program operation subroutine shown in S4143 of FIG. 41B will be described with reference to the flowcharts of FIGS. 42A and 42B. In this subroutine, the person mode,
Calculation T according to the mode set by the mode setting operation among landscape mode, moving object mode, and proximity mode
v, the calculation Av, and further convert them into the control Tv and the control Av actually used in the control.

First, in step S4201, the fv calculation subroutine is called, and the focal length detecting mechanism 102 of the photographing lens 12 is calculated by the following equation: fv = log (focal length f) / log2.
Is converted into a value that can be used as an apex value, and a converted focal length fv is obtained. further,
The Tvf calculation subroutine is called, and the camera shake limit Tvf of the shutter speed is obtained from the equation Tvf = (3/4) × fv + 2 (S4203). Also, the Avf calculation subroutine is called, and Avf = AvMIN + 1 + Avf shift Avf shift = (5/4) × (6.5−fv) where 0 ≦ Av
The optimum photographing Av value Avf is obtained by the equation of f shift ≦ 2. This optimum shooting Av value Avf is a value for determining an optimum aperture value based on the focal length when the background is to be blurred or when the entire depth is to be clearly shot by increasing the depth of field. In other words, it is the absolute amount of how far down from the opening.

In step S4207, steps S4119 to S4119 in FIG.
Using the coefficients a, b, etc. corresponding to the respective AE modes set in S4133, the calculation Tv is obtained by the following equation: coefficient a × light amount Lv + coefficient b.

This calculation Tv at a predetermined focal length in the selected mode is calculated as the minimum shutter speed TvMI specific to the camera.
It is compared with N and the maximum shutter speed TvMAX, respectively (S4209, 4211). If the calculation Tv is smaller than the minimum shutter speed TvMIN, the minimum shutter speed TvMIN is put into the calculation Tv, and it is assumed that the minimum shutter speed TvMIN is set even though a shutter speed actually lower than that must be set. "1" is set to the Tv under flag (S4213), and S4217 is set.
Proceed to. Also, the calculation Tv is the maximum shutter speed TvMA
If the shutter speed is larger than X, the maximum shutter speed TvMAX is included in the calculation Tv, and the Tv over flag is set to "1" assuming that the maximum shutter speed TvMAX is set even though the shutter speed actually needs to be set higher. Then (S4215), the process proceeds to S4217.

In S4209, when the calculation Tv at the predetermined focal length of the selected mode is equal to or higher than the minimum shutter speed TvMIN and equal to or lower than the maximum shutter speed TvMAX, "1" is set to both the Tv under flag and the Tv over flag. The process proceeds to S4217 without setting. S421
7, the CAL shown in FIG. An Av (Av calculation) subroutine is called, and the calculation T
An appropriate operation Av corresponding to v is obtained.

In S4219, CAL It is checked whether the calculation Av set in the Tv subroutine is a value exceeding the first Av boundary AvL1 calculated in the selected mode. As a result, if the operation Av exceeds the first Av boundary AvL1, the process jumps to S4243 to execute the P shift operation process, checks the direction and amount of the program shift, and checks the operation suitable for the program to be shifted. Tv and operation Av are obtained. If the operation Av is equal to or smaller than the first Av boundary AvL1, the process advances to step S4221 to put the first Av boundary AvL1 into the operation Av. This determines the Av value. The Tv subroutine (FIG. 43) is called, and the Tv corresponding to the calculated Av value is
The v value is obtained (S4223).

In S4225, the calculation Tv obtained in S4223 is further replaced with the first Tv boundary Tv calculated in S4203.
Compare with vL1. As a result, if the operation Tv exceeds the first Tv boundary TvL1, the process jumps to S4243 and returns to P424.
A shift operation process is executed to check the direction and amount of the program shift, and obtain an operation Tv and an operation Av suitable for the program to be shifted. The operation Tv is the first T
If it is less than or equal to the v-boundary TvL1, the process advances to step S4227 to put the value of the first Tv-boundary TvL1 into the calculation Tv. As a result, the Tv value is determined.
The Av subroutine is called again, and the operation Av corresponding to the operation Tv is calculated.

Further, it is checked whether or not the calculated Av value is larger than the second Av boundary AvL2 (S423).
1) If the operation Av exceeds the second Av boundary AvL2, the process jumps to S4243; otherwise, the process proceeds to S4233.
Then, the value of the second Av boundary AvL2 is set as the calculation Av. This determines the operation Av.
CAL at 35 The Tv subroutine is called again to calculate the operation Tv according to the operation Av. Further, this calculation Tv is compared with the minimum shutter speed TvMIN (S
4237) If the calculation Tv is larger than the minimum shutter speed TvMIN, the process jumps to S4243; otherwise, the minimum shutter speed TvMIN is put into the calculation Tv. This determines the Tv value. The Av subroutine is called again (S4241), and an operation Av corresponding to the operation Tv is obtained.

In S4243, a P (program) shift operation subroutine is called, the shift amount of the program line previously set and input to the ROM is obtained, and the operation Tv is set as a control Tv actually used for control. The calculation Av is set as the control Av actually used for control (S
4245), and return.

[CAL] Tv ”Next, in accordance with the flowchart of FIG. 43, CAL which is a process of setting an appropriate Tv value and regulating the Tv value to a controllable range. The Tv (Tv calculation) subroutine will be described. First, the Tv under flag and the Tv over flag are cleared (S4301), and the value obtained by the formula of the light amount value Lv−the calculation Av is put into the calculation Tv (S430).
3).

This calculation Tv is compared with the camera-specific minimum shutter speed TvMIN and maximum shutter speed TvMAX (S4305, 4307). As a result, if the calculation Tv is smaller than the minimum shutter speed TvMIN, the minimum shutter speed TvMIN is set as the calculation Tv, and the minimum shutter speed TvMIN is set even though a shutter speed actually lower than that has to be set. Then, "1" is set to the Tv under flag (S4309), and the routine returns. The calculation Tv is the maximum shutter speed TvMAX
If it is larger, the maximum shutter speed TvMAX is set to the calculation Tv, and the maximum shutter speed TvMAX is actually set higher than that.
Is set, the Tv over flag is set to "1" (S4311), and the process returns.

In step S4305, the calculation Tv
Is greater than the minimum shutter speed TvMIN,
7 and the calculation Tv is changed to the maximum shutter speed TvMA
If it is less than X, return. Therefore, this CA
L The Tv subroutine limits the shutter speed used in the AE operation program shift to a controllable range.

[CAL] Av] Then, according to the flowchart of FIG.
CAL, which is a process of setting the value and regulating the Av value to a controllable range The Av (Av calculation) subroutine will be described. First, in S4401, the Av under flag and the Av over flag are cleared, and the value obtained by the light amount value Lv−the calculation Tv is set in the calculation Av (S440).
3).

This calculation Av is compared with the minimum aperture value AvMIN and the maximum aperture value AvMAX (S4405, 440).
7). As a result, if the calculation Av is smaller than the minimum aperture value AvMIN, the minimum aperture value AvMIN is set to the calculation Av, and the minimum aperture value AvMIN is set even though the aperture must be further narrowed down. 1 "is set (S4409) and the routine returns.
If the calculation Av is larger than the maximum aperture value AvMAX, the maximum aperture value AvMAX is set to the calculation Av.
Assuming that MAX has been set, the Av over flag is set to "1" (S4411), and the routine returns.

In S4405, the operation Av
However, if it is equal to or larger than the minimum aperture value AvMIN, the process proceeds to S4407, and if the calculation Av is equal to or smaller than the maximum aperture value AvMAX, the process returns. Therefore, this CAL By the Av subroutine, the aperture value used in the AE calculation program shift is limited to a controllable range.

“P Shift Operation” The P (program) shift operation subroutine shown in FIGS. 42A and 42B will be described with reference to the flowchart shown in FIG. First, in step S4601, a sub P shift subroutine is called to determine the shift amount and shift direction of the learning program line. As a result, when the total program shift amount is obtained, the P shift prohibition flag is checked (S4603), and if "1" is set in the P shift prohibition flag, the process returns and exits, and the program shift is not performed. If "0" is set in the flag, S
Proceeding to 4605, it is checked whether the entire program shift amount is zero. If the entire program shift shift amount is 0, that is, if it is determined that the program line does not need to be shifted, return. Otherwise, that is, if the program line is to be shifted, check all P shift direction bits and shift. The direction is determined (S4607).

As a result, "1" is set to all P shift direction bits.
Is set, and the shift direction is negative.
If the program lines indicated by A and 48B are to be shifted in the upper left direction in the figure, a value obtained by subtracting the total P shift amount from the calculation Tv is set as the calculation Tv to set a lower shutter speed (S4623). Further, it is checked whether or not the calculation Tv is smaller than the minimum shutter speed TvMIN. If the calculation Tv is smaller than the minimum shutter speed TvMIN, the calculation Tv is set to the minimum shutter speed TvMIN (S4627).

In S4607, if all the P shift direction bits are set to "0" and the shift direction is positive, that is, if the program lines shown in FIGS. 48A and 48B are to be shifted to the lower right in the figure, , S4609, and sets a value obtained by adding the total P shift amount to the calculation Tv,
Set the shutter speed faster. Further, it is checked whether or not the calculation Tv is larger than the maximum shutter speed TvMAX (S4611). If it is higher, the maximum shutter speed TvMAX is set in the calculation Tv (S4613), otherwise, the process goes to S4615.

In S4615, the CAL shown in FIG. A
The v subroutine is called to calculate the operation Av, and in S4617 and S4619, the Av over flag and the Av under flag are checked. As a result,
When “1” is set in the Av over flag,
If "1" is set in the Av under flag and the Av under flag, the flow advances to S4621 to proceed to CAL, respectively. Tv subroutine is called, and Tv according to the operation Av at that time is called.
Calculate the value. If "0" is set in both the Av over flag and the Av under flag, the process returns.

The program line shown in FIG.
FIG. 8A shows in more detail the one in the person mode described in FIG. 8A, and the features are as follows. The first camera shake limit Tvf on both the wide side and the tele side.
(= TvL1) is set for each. The wide side is set so as to be suitable for group photography and shooting of a person in the landscape. The aperture can be narrowed down to sharply express both the landscape and the person. The tele side is set so as to be suitable for portrait and bust-up shooting, and opens the aperture to make a person appear. In the normal photographing area, the aperture control level is reversed.

As described above, the program line relating to the person mode is set to open the aperture from the low-speed shutter speed range to the camera shake limit on the wide side and the tele side, and at the camera shake limit, the shutter speed is fixed and the aperture is set to a predetermined value. Since the setting is made to change the value, it is possible to cope with not only portraits but also general photographing of a person, and it is possible to provide a camera provided with a program line in a person mode in which prevention of camera shake and the like is taken into consideration. Also, the change in aperture value at the camera shake limit is narrowed down to three steps on the wide side,
Because the tele side is set to stop down one step,
The wide side can be set so as to be suitable for group photography and shooting of a person in a landscape, and the aperture can be narrowed down to express both the landscape and the person sharply.

The program line shown in FIG. 49B shows the program line in the landscape mode shown in FIG. 49A in more detail, and has the following features. From near to distant views, you can take focused pictures regardless of the focal length. In the low-luminance region, the aperture is narrowed down by one step from the open state, and the aperture is narrowed down from the second camera shake limit fv to the minimum aperture. By stopping down from the full aperture, it is possible to eliminate insufficient peripheral light and improve image performance.

As described above, in the landscape mode program line, the aperture is set to be one step smaller than the open aperture value at the focal length from the low shutter speed range to the vicinity of the camera shake limit regardless of the focal length. . For example, at a focal length of 28 mm, the aperture is reduced by one step from AvL2 which is the open aperture value.

In the program line in the landscape mode, the exposure value Ev is 6/2 in the portion indicated by G after the vicinity of the camera shake limit.
It is set to change with the inclination of. That is, as described above, Tv value = coefficient a × light amount value Lv + coefficient b, and in landscape mode, the coefficient a is set to 2 in S4223.
/ 8, so that when the light amount value Lv increases by 1, T
The v value increases by 2/8. Av value = light amount value Lv
−Tv value, when the light amount value Lv increases by 1, Av
The value increases by 6/8. Thus, the Av and Tv values are 6:
2, the program line changes with a slope of 6/2. In FIG. 48, the numbers in parentheses are the apex values corresponding to the shutter speed and the aperture, respectively.
50B, 51B, 52B, and 55C have the same meaning.

Furthermore, the program line shown in FIG.
FIG. 50A shows the moving object mode shown in FIG. 50A in more detail, and the features are as follows. A third camera shake limit Tvf + 1 is set, and the camera shake limit Tv is raised by one step from the first camera shake limit.

The program line shown in FIG. 51B shows the program line in the proximity mode shown in FIG. 51A in more detail, and has the following features. In the low-luminance range, both the wide-side and the tele-side are programs that prioritize the aperture one step down from the maximum aperture. From the camera shake limit, F8 is set regardless of the focal length.

As described above, in the program line relating to the proximity mode, the aperture is fixed at a predetermined value from the low-speed shutter speed range to the camera shake limit, the aperture is changed by approximately one step at the camera shake limit, and the aperture is fixed at F8. Is set to perform control after the camera shake limit, it is possible to obtain a camera having an exposure mode that can be applied not only to the macro area of the zoom lens but also to the macro lens as a close-up mode. Also, the aperture can be set to a value slightly higher or lower than F8. Further, in close-up shooting, the shutter speed is slowed down due to an excessively narrow aperture due to a shallow depth of field, and camera shake and subject shake are likely to occur. The aperture value is narrowed down by approximately one step, and control is performed using this aperture value after the camera shake limit, so that the above-described camera shake and subject shake can be avoided.

[Sub P Shift] Here, the sub P shift subroutine shown in S4601 of FIG. 46 will be described with reference to the flowchart shown in FIG. In this subroutine, the shift amount of the origin and the shift amount of the program line due to learning, that is, the shift amount of the entire program are obtained.

In S4501, the main switch 11
X = 5 modes that can be changed when 0 is switched to the picture position: green mode, portrait mode, landscape mode, moving object mode, and proximity mode.
Since the program line is set corresponding to each of 0 to 4, the person mode in which the program line should be actually shifted (FIG. 48)
A, 48B), landscape mode (FIGS. 49A and 49B), moving object mode (FIGS. 50A and 50B), and proximity mode (FIG. 51).
When selecting A, 51B), X is set to a value obtained by subtracting 1 from five AE mode numbers corresponding to X = 0 to 4, that is, AE mode-1.

Further, the origin shift amount and the origin direction bit corresponding to the read values are read from the RAM (S4503, S4505), and the P shift direction bit is checked to determine whether the program shift direction is positive. It is checked whether the value is negative (S4507). If it is positive, the process jumps to S4511. If it is negative, it is determined that the program shift amount is negative, and this is negatively converted, that is, its absolute value is converted into a negative value (S4509).

In S4511, it is checked how the origin has been changed by "learning" using the origin direction bit. As a result, if the origin shift direction is negative, the negative conversion, that is, the absolute value processed origin shift amount is converted to a negative value and used. If the origin shift amount is positive, it is used without negative conversion ( S4513).

Then, the shift amount of the entire program line is obtained by adding the origin shift amount to the program shift amount (S4515). Further, in S4517, it is checked whether or not the entire shift amount is smaller than 0. If it is smaller, the process proceeds to S4517, where the entire program shift amount is subjected to absolute value processing, and "1" is set to all P shift direction bits. . In S4515, the entire shift amount is 0.
If it is, return. The absolute value processing prevents the value of the exposure factor for calculation from becoming negative,
The accuracy of each exposure factor is adjusted to 1/8 Ev steps to facilitate the addition / subtraction apex operation without considering the operation accuracy.

[CHK TvAv ”CHK shown in S4145 of FIG. 41D, which is a process of detecting whether or not the calculation Tv and the calculation Av are the limit values. Tv
The Av subroutine will be described with reference to the flowchart shown in FIG. First, in S5701, the control Tv value and the maximum shutter speed TvMA calculated in each mode are set.
It is determined whether or not X is equal, and if they are equal, the maximum shutter speed TvMAX flag is set to "1" (S4703),
Otherwise, jump to S4705. S4705
In, it is determined whether or not the control Tv value calculated in each mode is equal to the minimum shutter speed TvMIN, and if they are equal, the minimum shutter speed TvMIN flag is set to "1"(S4707); otherwise, the process proceeds to S4709. Jump.

In S4709, it is determined whether or not the control Av value calculated in each mode is equal to the maximum aperture value AvMAX. If they are equal, the maximum aperture value AvMAX flag is set to "1" (S4711). If not, S4
Jump to 713. In step S4713, the control Av value and the minimum aperture value AvMI calculated in each mode.
Judge whether N is equal or not, and if they are equal, the minimum aperture value AvMI
The N flag is set to "1" (S4715), and otherwise returns. "Learning"

Next, the processing related to learning which is a feature of the present invention will be further described with reference to FIGS. 55 to 59 and 85 to 90.
This will be described with reference to FIG. The learning of the present invention relates to a program shift situation in the program exposure mode. In other words, when the photographer releases the program while shifting the program according to his / her preference, the number of releases is counted, and when the count reaches a predetermined number or more, a program line is placed in the shift direction. The data to be shifted quantitatively is stored as learning data. And
After this storage, a shutter speed and an aperture value are set along a learning program line obtained based on the learning data,
Further, the configuration is such that the program shift and learning storage are executed with reference to the learning program line.

The program shift in this embodiment is
This means changing a combination of a shutter speed and an aperture value by translating a program line (default program line) obtained by normal program exposure processing along the exposure value Ev line. For example, in the program diagram of the photographing lens having the open F value of 3.5 and the minimum aperture F value of 22 shown in FIG. 55C, when the default program line is shifted in the positive direction by 0.5 Tv or 1.0 Tv, the program line or And conversely, 0.
When a program shift is performed by 5 Tv or 1.0 Tv, a program line is obtained. However, when the shutter speed or the aperture value exceeds the controllable range, for example, Ev
In the case of = 9, the learning program line, since the aperture value has reached the open value, the program cannot be shifted in the forward direction from here, so that no learning is performed. When the shutter speed Tv is added by a predetermined value, the aperture value Av is subtracted by a predetermined value.

Moving a point on the default program line as the origin and moving this origin along the exposure value Ev line to the learning program line is called origin movement and origin shift.
The amount of movement of the shutter speed Tv that changes due to the movement of the origin is called the origin movement amount or shift amount, the direction from the default program line to the learning program line is called the origin direction, and a point on the learning program line is called the learning origin. FIG. 55C
Shows a simple program diagram for easy understanding of the program shift operation of the present invention, but the present invention is not limited to this, and in the present embodiment, a person mode, a landscape mode, a moving body mode and Program shift and learning can be performed in the proximity mode.

In this single-lens reflex camera, the program (P) shift amount and the program (P) shift direction are set by operating the up / down lever 28 (up / down switches 78 and 80) (see FIG. 27), and the photometry switch is set. When 70 is turned on, the shutter speed Tv obtained by the normal program calculation process is changed by the program shift amount, and the proper aperture value Av is calculated again based on the changed shutter speed Tv and proper exposure value Ev. Configuration. In the present embodiment, an independent learning function is provided for each of the four program exposure modes of the portrait mode, the landscape mode, the moving object mode, and the proximity mode, and when any one of the four exposure modes is selected, The learning function works independently.

FIGS. 58 and 59 show various data necessary for the learning function, the areas of the EEPROM 106 and RAM for storing the data, the data formats and their relationships, and the RA.
The format of M is shown. The data required for learning includes the origin shift amount, the origin direction, the number of learning releases,
There are a previous learning direction, a program shift amount, and a program shift direction.

The program shift amount is the absolute value of the shutter speed Tv shifted from the reference program line, with the high-speed shutter (including 0) being positive (+) and the low-speed shutter being negative (-). Positive or negative is identified by a P shift direction bit (positive is “0”, negative is “1”). The reference program line is based on the learning program line when the learning result is stored, and is based on the default program line when the learning result is not stored. The origin shift amount is a difference between the shutter speed Tv in the learning program line saved by learning and the shutter speed Tv in the default program line, and the magnitude is represented by an absolute value, and the learning program line is based on the default program line. Is positive when the shutter is closer to the high-speed shutter than the default program line, and negative when it is closer to the low-speed shutter. The positive / negative is identified by an origin direction bit (positive: “0”, negative: “1”). Each time the exposure is completed, the number of times of learning release is counted up based on one condition that the current program shift direction and the previous program shift direction are the same. (Positive: “10”, negative: “01”).

As an area for storing the four kinds of data of the above-mentioned origin shift amount, the origin direction bit, the number of learning releases, and the previous learning direction bit, two bytes are stored in the EEPROM 106 for each of the four program exposure modes.
TDYCNT (X), GENPSFT (X)｝ and RA
2 bytes corresponding to M @ STDYCNT (X), GEN
PSFT (X)}, and 4 bytes (ALLPSFT, SETPSF) in RAM as a common data area
T, STDYCNT and GENPSFT) are prepared. The program shift amount uses 0 to 6 bits of SETPSFT, the program shift direction uses the 7th bit of SETPSFT, and the origin shift amount is 0 to 6 bits of GENPSFT.
Use the 7th bit of GENPSFT as the origin direction bit and the number of learning releases from 0 to 0 in STDYCNT.
5 bits for learning and the previous direction bit for learning is 6 for STDYCNT.
And the 7th bit are used. Furthermore, the total program shift amount (program shift amount from the origin) is ALLP
SFT 0-6 bits, all shift direction bits ALL
The 7th bit of PSFT is used.

[Learning Calculation Processing] The learning processing will be described in more detail with reference to the flowcharts shown in FIGS. FIG. 55A, 55B
Is a flowchart relating to a learning calculation process, which is a subroutine called in step S1415 of the release process in FIG. In this embodiment, the learning is stored when the learning release is performed a predetermined number of times in the same direction of the program shift, that is, the learning program line is changed.

When entering the learning calculation processing, first, the learning RUN flag for controlling the lighting of the learning picture 56S is cleared, and whether or not the learning mode is set (the learning mode flag is set to "1").
It is checked whether the program shift amount is 0, and if the learning mode is not the learning mode (the learning mode flag is “0”), or if the program shifting amount is 0 even in the learning mode, the number of learning releases is not counted. Return to the release processing subroutine (S5501-S
5505).

When the learning mode flag is set and the program shift amount is not 0, it is determined whether the program shift amount is larger than the learning change level set in the learning change level changing process of FIG. If the comparison is higher than the learning change level, the number of learning release times 1 is set as the change release number,
If it is equal to or less than the learning change level, the number of times of learning change 2 is set as the number of change releases (S5503, S5505).
And S5507, S5509 or S5507, S55
11).

Next, the RAM areas STDYCNT (X), GENPSFT corresponding to the selected program exposure mode (AE mode number X minus 1) are selected.
From (X), the origin shift amount, the origin direction bit, the number of learning releases and the previous learning direction bit are read out, and the origin shift amount and the origin direction bit are stored in the RAM area GENPSFT.
The number of learning releases and the previous learning direction bit are stored in RAM.
The memory is stored in the area STDYCNT (S5513 to S55).
21). Then, the learning RUN flag is set, the learning release number is added once, and it is checked whether the learning release number is less than the change release number. If the learning release number is less than the changing release number, the process proceeds to S5529 to count the learning release number.
If it is above, FIG. 57A for learning up-down processing,
The process proceeds to the learning U / D process of 57B (S5523 to S552).
7).

If the learning release frequency is less than the change release frequency, the program shift direction has not changed from the previous program shift direction (learning direction) (the P shift direction bit is “1” and the learning previous direction bit is “0”).
On the condition that "1" or the P shift direction bit is "0" and the previous learning direction bit is "10", the process directly proceeds to the learning store 2 processing (S5529, S5531 or S5529, S5553). When the release is performed in the state of the program shift direction (or the shift amount is 0), the number of times of learning release is counted up each time the release is performed. Each time the release is performed in the program shift direction (or the P shift amount is 0), the number of learning releases is counted up.

Previous learning direction (program shift direction)
Is negative and the current program shift direction is positive, the program shift direction has changed from negative to positive, so the process proceeds to learning reset 1 processing to start a new learning, sets the number of learning releases to one, and sets the learning previous direction. Bit "10"
(Correct) is set, and the process proceeds to the learning store 2 process of updating only the number of learning releases and the previous learning direction bit (S55).
29, S5531, S5541). Conversely, when the previous learning (program shift) direction is positive and the current program shift direction is negative, the program shift direction has changed from positive to negative, so the process proceeds to learning reset 2 processing to start new learning. , The number of learning releases is set to one, and “01” (negative) is set in the previous learning direction bit, and the process proceeds to learning store 2 processing (S5529, S5533, S555).
1).

“Learning Store 2 Process” The learning store 2 process is a process for updating and storing the number of learning releases and the previous learning direction bit, and does not change the origin shift amount and the origin direction bit. That is, the learning release frequency and the previous learning direction bit are respectively set to R corresponding to the current program exposure mode (AE mode number X).
Memory in a predetermined bit of the AM memory area (X) (S5
611, S5613). Then, the contents of the RAM memory area (X) relating to learning are written into the corresponding 2-byte memory area of the EEPROM 106, and the process returns (S5615).

[Learning Up / Down Processing] When the number of learning releases becomes equal to or greater than the number of changing releases, the learning result is stored, that is, learning U for executing the origin shift is performed.
The / D process will be described with reference to the flowcharts shown in FIGS. 57A and 57B and the program diagram shown in 55C. When entering the learning U / D process, first, the program shift direction is checked. If the current program shift direction is positive (the P shift direction bit is “0”), the learning up process is performed, and if the current program shift direction is negative. When the P shift direction bit is "1", the learning down process is executed. Assuming that the default program line or the learning program line has a program shift amount of 0, the external display LCD panel 34 displays an origin display mark (triangle mark).
A black circle 58f above 58h is turned on. In addition, FIG.
The display in FIG. 90 is for Ev (Lv) = 13.

[Learning Up Processing] In the learning up processing, first, the previous learning direction (program shift direction) is checked, and the previous learning direction is negative (the previous learning direction bit is negative “10”), that is, the current program shift. If the direction has changed from the previous time, the origin shift amount and the origin direction bit are not updated, so the process proceeds to learning reset 1 processing (S5711). For example, FIG.
In the current learning program line, the previous program shift is −0.5, −1.0 Tv or less (or direction), and the current program shift is +0.5, +1.0 Tv or more. (Or direction). For example, the previous time is the shift state shown in FIG. 90, and the current time is the shift state shown in FIG. 86.

When the program shift direction is the same as that of the previous time, or when the program shift was not performed the previous time (shift amount is 0), 0 is added to the number of learning releases.
S0115-S
The process proceeds to an origin shift amount setting and program shift amount setting step of 5727 (S5711, S5713). For example, assuming the current learning program line, the previous program shift is 0, +0.5, +1.5 Tv or more (or direction) and the current program shift is +0.5 Tv or more (direction). Is the case. The default (learning) program line is displayed as shown in FIG. 86 when the program shift is +1.0 Tv.

The origin shift amount is determined according to the origin direction, that is, whether the learning program line is in the positive direction (including the case where the learning program line coincides with the default program line) or in the negative direction. 0.5Tv is added or subtracted (S5715, S5717, S5719 or S571
5, S5721).

When the learning program line is shifted in the forward direction from the default program line (that is, the origin direction bit is positive “0”) and the shift amount is less than 2, the origin shift amount is added by 0.5 Tv. Yes (S5715
To S5719). Then, the value of 0.
After subtracting 5 Tv from the program shift amount, the process proceeds to the learning store 1 process (S5727). In this embodiment, since the maximum value of the origin shift amount is limited to 2Tv, when the origin shift amount is equal to or more than 2Tv, the origin shift (shift of the learning program line) is not executed and S5717 is executed.
To learning store 1. By the above-mentioned up processing, for example, when the default program line is the learning program line and the program shift is +0.5 Tv (direction), the learning program line changes from the blank to the empty line. When the default (learning) program line adds +0.5 Tv to the origin shift amount from the state of FIG. 86 when the program shift is +1.0 Tv, the lighting of the black circle 58f changes as shown in FIG. 87, and the program line changes to +0. Instead of the learning program line shifted by 5 Tv, the program shift is +0.5 Tv. When the program shift clear processing is performed, the program shift amount from the learning program line is cleared and displayed as shown in FIG.

When the learning program line is shifted in the negative direction from the default program line, that is, when the origin direction bit is “1”, the origin shift amount is set to 0.5 Tv.
A minute is subtracted (S5715, S5721). Then, when the origin shift amount becomes 0, “0” is inserted into the origin direction bit, and
If the origin shift amount does not become 0, the program shift amount is subtracted by 0.5 Tv, and the process proceeds to the learning store 1 process (S5723, S5725, S5727 or S57).
23, S5727). By the above up processing, for example, the default program line is the current learning program line, and the program shift is +0.5, +1.0,
In the case of +1.5 Tv or more (in the direction), the new learning program line changes to.

“Learning Down Processing” In the learning down processing, in step S5701, the program shift direction is negative (P shift direction bit is “1”).
Enter when it was. In the learning down process, first, whether or not the program shift direction has changed from the previous time is checked by using the previous learning direction bit.
1)), the process proceeds to the learning reset process 2 and the learning content is not updated (S5731) If the program shift direction has not changed from the previous time (the previous learning direction bit is "1").
0 ”), the learning release number is set to 0, and a negative“ 01 ”is set in the previous learning direction bit (S5733).

Then, depending on the direction of the origin, that is, the learning program line is more negative than the default program line,
Alternatively, the origin shift amount is added or subtracted depending on whether the object is in the same direction or in the positive direction (S5735, S5737 or S573).
5, S5743, S5745).

When the origin direction is positive, the origin shift amount is subtracted by 0.5 Tv (S5735, S5737). Here, since the origin shift amount after the subtraction may be less than 0 (−0.5 Tv), it is checked whether the origin shift amount has become less than 0, and if it is less than 0, the absolute value processing of the origin shift amount Is performed, the origin direction bit is changed to “1” (negative), the flow advances to S5747, and the origin shift amount after the subtraction is 0.
In the above case, the process directly proceeds to S5747 (S573)
9, S5741). By the above down processing, for example,
The default program line is the learning program line, and the program shift is -0.5, -1.0, -1.5
In the case of Tv or less (,, direction), a new learning program line is set. FIG. 89 shows a display when the learning program line is set and the program shift is -1.5 Tv, and FIG. 90 shows a display mode when the learning program line is learned in this state and becomes the learning program line.

When the origin direction is negative, the origin shift amount may exceed the limit value (2Tv). Therefore, it is checked whether the origin shift amount is equal to or more than the limit value. Addition, subtraction of 0.5 Tv from the program shift amount proceeds to S5749, and if it is not less than the limit value, jumps to S5749 (S5735, S5743 to S5743).
5747, S5749 or S5735, S5743,
S5749). By the above-described down processing, for example, when the default program line is a learning program line and the program shift is −0.5 Tv or less (direction), a new learning program line becomes.

Then, since the program shift amount subtracted in S5747 may become 0, when it becomes 0, the P shift direction bit is changed to “0” (positive), the program proceeds to the learning store 1, and the program shift amount is changed. If is not 0, the process directly proceeds to the learning store 1 (S5749, S5749).
5751).

“Learning Stores 1 and 2” Next, the learning store 1 processing for storing the learning status in the EEPROM 106 will be described with reference to FIG. First, the origin shift amount and the origin direction bit set by the learning up / down processing are respectively stored in the memory area STDYCNT of the RAM corresponding to the current program exposure mode.
(X), the memory is stored in predetermined bits of GENPSFT (X), and then the process proceeds to the learning store 2 process (S5601, S560)
3).

In the learning store 2 process, the number of learning releases and the previous learning direction bit are stored in predetermined bits of the RAM area (X) corresponding to the current program exposure mode (S5611 and S5613). Then, RAM memory areas STDYCNT (X), G for learning
The contents of ENPSFT (X) are stored in a corresponding 2-byte memory area STDYCNT (X), G of EEPROM 106.
After writing to ENPSFT (X), return (S
5615).

As described above, according to the single-lens reflex camera equipped with the learning function of the present invention, the photographer selects the person mode, landscape mode, moving object mode or close-up mode as the program exposure mode and selects the learning mode. When the program is shifted a predetermined number of times in the positive or negative direction, the program line shifts (moves to the origin) by 0.5 Tv steps in the shifted direction, and after the shift, the shutter is released based on the shifted learning program line. The speed and the aperture value are set, and the program shift and learning are performed. That is, the single-lens reflex camera of the present embodiment, when the photographer shifts the program and releases it, learns the shift tendency for each release and learns a predetermined number of times.
The learning result is updated (saved), the shutter speed and the aperture value are set based on the learning result, and learning is newly performed.

As described above, in this embodiment, the combination of the program shift amount and the number of learning changes can be selected. However, the combination is not limited to this. Often, the number of times of learning is changed in two steps at a predetermined shift amount.
A configuration in which the number of times of learning is changed in three or more stages or according to the shift amount is also possible.

In the present embodiment, the learning is changed in 0.5 Tv step units, but is not limited to this value. For example, it may be a 1.0 Tv step or a 0.3 Tv step, or may be configured to skip to a specific Tv value. In the present embodiment, the program processing, the program shift processing, and the learning storage processing are executed with priority given to the shutter speed Tv. However, the above-described processing may be executed with priority given to the aperture value Av.

As described above, the camera of this embodiment can operate in the PF setting mode in which the setting items of the camera functions can be changed. The transition from the normal shooting mode to the PF setting mode can be made by holding down the mode button 40 and the drive button 38 simultaneously for two seconds or more. During operation in the PF setting mode, setting items can be switched by operating the mode button 40, and the setting contents of each setting item can be changed with the up / down lever 28. After the setting is completed, if the mode button 40 and the drive button 38 are simultaneously pressed again for two seconds or more, the setting contents are written into the EEPROM 108 and become effective. By this operation, the operation mode returns from the PF setting mode to the shooting mode. If the main button 36 is turned off while operating in the PF setting mode,
Alternatively, if the setting operation is not performed for one minute or more during the operation in the PF setting mode, the PF setting mode is interrupted, and the setting contents are discarded without being written to the EEPROM 108.

Here, the mode button 40 in this embodiment is used.
The up / down lever 28 corresponds to the data changing means of the first aspect, and the mode button 40 and the drive button 38, which can be simultaneously pressed for two seconds or more, correspond to the predetermined operation member. Further, the process of writing to the EEPROM 108 in S2011 of FIG. 20 executed by the CPU 20 corresponds to the data updating unit of the present invention.
