Accordingly, of the light receiving period τ between the time t0 and the time t2 in the photosensitive section, the period Tv (= τ−φ) between the time t1 and the time t2 is a substantial exposure period of the CCD 23, and the film image is captured. Period. The exposure period Tv corresponds to the shutter speed of a normal camera. As is apparent from FIG. 10, the exposure period Tv of each film image can be controlled by controlling the phase φ. That is, the larger the phase φ, the shorter the exposure period Tv and the faster the shutter speed.

ive Double Sampling) circuit, analog amplifier, and signal processing circuit such as white balance (WB) circuit.
The image signal (analog signal) of each color of R, G, and B output from the CD 23 is subjected to predetermined signal processing.

In the analog processing section 14, R,
After the noise of the G and B image signals is suppressed by the CDS circuit, the image signals are amplified to a predetermined level by an analog amplifier.
Further, the white balance of the image signal is automatically adjusted by the WB circuit.

(Referred to as an image) and has a multi-display function of reproducing and displaying the image on the monitor TV2. Since the image of each frame F in the multi-image is smaller in size than the reproduced image, in the multi-image imaging, an imaging process different from the imaging process in the normal reproduction process is performed.
The captured image data is reduced to a predetermined size by a thinning process and stored in the first image memory 27.

In imaging for a multi-image, a part of pixel data (data obtained by each pixel constituting the CCD 23) constituting the film image is fetched by skip-scanning the film image. This is based on the fact that the image of each frame F constituting the multi-image is smaller than the normal reproduced image and does not necessarily require all the pixel data constituting the film image since high image quality is not required. It is.

In the above interlaced scan, only the line position at which an image is to be captured is scanned at a scan speed during normal reproduction (hereinafter referred to as a main scan speed), and other line positions are scanned at a higher speed than the scan speed during normal reproduction. Is what you do. For example, the first line from the first line, the second line
.., And only the line position of the 6k (k = 1, 2,...) Line, which is a line position that is an integral multiple of 6, is picked up. Is approximately six times as fast as the main scan speed, and the captured image G 'is reduced in the feed direction of the film 11 with respect to the original film image G (see FIG. 11A). (B), see). This reduction rate (L '/ L) is substantially inversely proportional to the feeding speed of the film 11, and is about 1/6.

When the captured image G 'is stored in the first image memory 27 from the first process circuit 26, the required reduction rate (H') is also required in the vertical direction (the width direction of the film 11).
/ H), the data constituting the captured image G ′ is thinned out at a predetermined pitch, and the reduced image G ″ is stored in the first image memory 27 as shown in FIG. .

Specifically, the distance between the hole 114 indicating the front end position of the film end portion 11C and the hole 115 indicating the rear end position is longer than the distance between the hole 111 indicating the front end position of each frame F and the hole 112 indicating the rear end position. Because of its short length, the scan time from the leading end position to the trailing end position is counted for each frame, and when the scan time is shorter than the previous scan time, the hole 115 (the trailing end position of the film end portion 11C)
Is determined to be detected. The details of the detection of the end position of the film 11 will be described later.

Next, the reproducing operation of the film image reproducing apparatus according to the present invention will be described with reference to the flowcharts of FIGS. 13 to 34 and the drawings.

FIGS. 13 to 18 are flowcharts of initialization processing (initialization) performed when the power switch 801 of the film image reproducing apparatus 1 is turned on.

When the power plug K3 is inserted into the outlet and AC power is supplied, this is detected (#
1) First, the light source heater 194 is turned on (# 3).
Subsequently, when the power switch 801 is turned ON by the operator (# 5), the preliminary driving of the CCD 23 is performed (# 5).
7), the power lamp 802 is turned on (# 9). The preliminary driving is a preliminary driving before the original imaging operation is performed in order to suppress the influence of the level change of the dark output that occurs immediately after the driving of the CCD 23 is started.

Note that the monitor T is connected to the film image reproducing apparatus 1.
If V2 is connected and the monitor TV2 has already been activated, for example, the entire display screen 3 of the monitor TV2 is displayed on a blue screen or the like, and the monitor TV2 also displays that the power of the film image reproducing apparatus 1 is ON.

Subsequently, an output signal (hereinafter, referred to as dark output data) of each pixel of the CCD 23 in darkness is fetched as correction data of the dark output level of the pixel data constituting the captured image, and the AE / AWB arithmetic circuit 39 (# 11), the light source 191 emits light (# 13).
The light source 191 automatically emits light after the processing of # 1 to # 11 is completed, but a light source switch (not shown)
May be provided separately, and may be performed based on an operation of the operator such as turning on the light source switch.

Subsequently, it is determined whether or not the film cartridge 9 is loaded in the film storage unit 10 (# 1).
5) If the film cartridge 9 is not loaded (NO in # 15), an unloaded message is output, the eject table 6 is pulled out of the film storage unit 10, the loading port is opened, and the film cartridge 9 is unloaded. Standby until set (# 17 to # 2)
1).

The above-mentioned unloaded message is displayed, for example, on the display unit 7.
28 in the display area 703 or the monitor TV2 of FIG.
This is performed by blinking the film mark FM shown in FIG. 3A or by separately providing an unloaded mark in the display area 703 and lighting the unloaded mark. Note that an unloaded message may be displayed as characters on the display screen 3 of the monitor TV 2, and a voice message such as “Please insert a film cartridge.” May be generated from the speaker 4.

Subsequently, when the film cartridge 9 is set in the film storage section 10 (YES in # 21), the compatibility of the film cartridge 9 and the film 11 (whether or not the film can be normally reproduced) is determined. Done (#
23, # 29).

The compatibility of the film cartridge 9 is determined, for example, as to whether it conforms to the cartridge standard, whether a developed film is stored (whether the alignment mark 93 of the film cartridge 9 is set to “PROCESSED”), or whether foreign matter is mixed. It is determined by checking the presence or absence.

If the film cartridge 9 is compatible (YES in # 23), after the display on the film winding is performed, the film information recorded in the bar code 94 of the film cartridge 9 is read (# 25, # 25). # 27) The suitability of the film 11 is determined from the film information (#
29). The suitability of the film 11 is determined by checking film sensitivity, film type (negative / positive), film standard, and the like.

Film cartridge 9 or film 11
Does not match (NO in # 23 or # 29), the film cartridge 9 is ejected from the film storage unit 10 (# 31), and the film cartridge 9 or the film 11
Is performed (# 33).

The nonconforming message flashes the film mark FM (see FIG. 28A) on the display area 703 of the display unit 7 or the monitor TV2, for example.
An error code is displayed in the display areas 704 and 705, and a nonconformity mark is separately provided in the display area 703.
This is performed by lighting the nonconforming mark. The nonconforming message may be displayed as characters on the display screen 3 of the monitor TV 2, and a voice message such as “this cartridge cannot be reproduced” may be generated from the speaker 4.

Film cartridge 9 and film 11
Is satisfied (YES in # 29), the light-shielding cover 98 of the film cartridge 9 is opened, and the reading process of the reader unit information is performed in accordance with a subroutine "reading of reader unit information" described later (# 35, # 37, # 39). When the power is turned off while the film cartridge 9 is loaded and the power is turned on again, if the film cartridge 9 is already loaded, the film 11 is loaded and the light-shielding lid 98 is already opened and Therefore, the reading process of the reader unit information is performed without performing the opening process of the light shielding cover 98 (# 35, # 39).

If the film cartridge 9 is loaded when the power is turned on (YES in # 15), it is determined whether loading has been completed (whether the film 11 has been pulled out to the image pickup section 11B) or not (# 41). If loading has been completed (YES in # 41), a film rewind display is performed, and the feed motor M is rotated at a high speed in the reverse direction (film 11).
The film 11 is rewound to the end position of the film leader 11A (until the hole 113 is detected) (# 43, # 45). The film rewind display is performed by, for example, the display area 703 of the display unit 7 and the monitor T.
This is performed by displaying a rewind mark FR shown in FIG. 28 (c) on V2.

Subsequently, it is determined whether or not the film information read from the film cartridge 9 during the previous loading of the film 11 is stored in the data memory 43 (# 47), and the film information is stored in the data memory 43. If not (NO in # 47), # 23 to # 39
Is performed and the film information is read, and if the film information is already stored in the data memory 43 (YES in # 47), the processing of # 23 to # 39 is not performed (the film information is not read). # 4 without performing the reading process)
9 (see FIG. 14).

Here, the reading process of the reader section information will be described. FIG. 19 is a flowchart of the subroutine "Read Reader Unit Information".

When the subroutine "Read Reader Unit Information" is called, low-speed forward drive of the feed motor M (winding of the film 11 at low speed) is started (# 14).
1), the counting of the predetermined time t1 is started by the timer T1 in the control unit 47 (# 143, # 145). The counting of the predetermined time t1 by the timer T1 is for determining the quality of the loading based on whether the loading is completed within the predetermined time.

If the loading of the film 11 is detected by the loading detector 35 within the predetermined time t1 (YES in # 147), the timer T1 is reset (#
149), the driving of the feed motor M is stopped (# 15)
1).

Subsequently, after the magnetic heads 18A and 18B are set at the reading position (# 153), the film 11 is rewound at a low speed and the leader portions recorded on the magnetic recording portions 116A and 116B of the film leader portion 11A. The information is read (# 157, # 159).

That is, the film 11 is placed in the unexposed area 11
The leader information recorded in the magnetic recording units 116A and 116B is read by the magnetic information reading control unit 33 while rewinding at a low speed until the hole 111 indicating the tip position of E is detected. The read reader unit information is sent to the control unit 4
7, and is stored in the data memory 43. The reason why the reader unit information is read while being rewound is that flatness can be easily obtained as compared with the case where the leader unit information is read while the film is being fed, and stable information reading can be performed.

When the reading of the reader section information is completed (YES in # 159), the driving of the feed motor M is stopped (# 161), and the magnetic heads 18A and 18B are reset to the retracted position (# 163). ), Return.

If the loading of the film 11 is not detected by the loading detector 35 within the predetermined time t1 (NO in # 165), it is determined that the loading is defective, and the initialization failure processing is performed according to the flowchart of "Initial NG". (# 167).

FIG. 20 is a flowchart of “Initial NG”. When the flow shifts to the “Initial NG” flow, the film 11 is rewound into the film cartridge 9 at a low speed, and during the rewinding period, the display area 7 of the display unit 7 is displayed.
03, a warning display indicating that the loading has failed is performed (# 171 to # 177). The warning display is displayed, for example, in the display area 703 of the display unit 7 of the film image reproducing apparatus 1.
Is performed by blinking the film mark FM (see FIG. 28A).

Subsequently, the operator issues an instruction to eject the film cartridge 9 or an instruction to reproduce the film cartridge 9 (eject switch 803 or reproduction switch 81).
6 (ON) is determined (# 179, # 179).
185), when a reproduction instruction is issued (YE in # 185)
S), a reproduction process of a film image described below is performed (#
187).

On the other hand, if the instruction to eject the film cartridge 9 has been issued (YES in # 179), it is determined whether or not the reader unit information has been read (# 18).
1). If the reader unit information is read, as in the case of a loading failure during loading after reading the reader unit information while rewinding it (Y in # 181)
ES), after the leader section information stored in the data memory 43 is deleted (# 183), the process returns to # 17 (see FIG. 13), and if the leader section information is not read (# 18).
(1; NO), the process returns to # 17 without erasing the reader section information in the data memory 43.

The reason why the reader unit information stored in the data memory 43 is erased in # 183 is that the reader unit information is not used and the process returns to # 17, and the film cartridge 9 is loaded again and the reader unit information is deleted. This is because there is a high possibility that the set information is read.

Referring back to FIG. 14, when the reader unit information reading process is completed, the loading of the film 11 is performed again (# 49 to # 61), and the base density is taken in during the loading process. Based on the read dark output data (# 11) and the reader unit information (# 39), a correction value in the signal processing of the captured image is calculated (# 57), and the iris 22 is set to a predetermined value. The aperture value (initial setting value) is set (# 59).

The correction in the signal processing of the captured image is as follows.
For example, level correction, shading correction, sensitivity variation correction between pixels, and film-based color correction (correction for removing the base density from the density of a captured image) for light intensity fluctuation of the light source are performed. The level correction, the shading correction, and the sensitivity variation correction are performed in the signal processing in the analog processing unit 24, and the correction value of each correction is calculated by the AE / AWB calculation circuit 39, and the calculation results are set in the analog processing unit 24. Is done.

The film-based color correction is performed by A / D
AE / AW performed in the signal conversion process of the converter
A / D based on the base density by the B operation circuit 39
The dynamic range of the converter 25 is calculated, and the calculation result is set in the A / D converter 25.

If the loading of the film 11 is not performed within the predetermined time t1 (YES in # 63), it is determined that the loading is defective as in the reader information reading process, and the above-mentioned "Initial NG" process is performed. (# 6
5).

If the loading of the film 11 is performed normally (YES in # 61), the flow shifts to # 67 (see FIG. 15), and the film 11 is wound up at high speed to the last frame F (by the feeding motor M). (High-speed normal rotation drive), and the frame information and the optical information 118 recorded on the magnetic recording units 117A and 117B of the film 11 are read (# 67 to # 7).
3). Subsequently, unexposed frames F are extracted from the read frame information, and the information of the unexposed frames is stored in the data memory 43 as frame information that does not need to be reproduced (# 75).

Subsequently, the base density is read in the film end section 11C, and the light quantity of the light source is checked by comparing the base density with a predetermined reference base density (# 81 to # 83). This light amount check of the light source is performed a plurality of times within a predetermined time t2 (##
77 to # 83), the difference (density difference) between the base density and the reference base density (density difference) (=
| Detected base concentration-reference base concentration |) is within a predetermined range ε
If it is larger than (YES in # 83), it is determined that the light amount of the light source is abnormal, and a light source abnormality warning is issued (# 85), and then the end processing is performed according to the flowchart of the "end sequence" shown in FIG.

The above-mentioned light source abnormality warning is performed, for example, by displaying an error code in the display areas 707 and 705 of the display unit 7 of the film image reproducing apparatus 1. Also, a message of the light source abnormality is displayed on the monitor TV2, and the speaker 4
, A voice message of a light source abnormality is generated.

Here, the termination processing will be described. When the flow shifts to the “end sequence” flowchart, a “power OFF” message is output (# 321). This message is displayed, for example, by rewinding the film on the display screen 3 of the monitor TV 2, emitting a sound such as “turn off the power” from the speaker 4, or blinking the power lamp 802 of the film image reproducing apparatus 1. Done.

Subsequently, the light source is turned off (# 32).
3) The film 11 is fed at high speed to the last frame F among the frames F for which the frame information needs to be rewritten (# 325). During the film feeding period, an indication during film winding or film rewinding is displayed. This display is displayed in the display area 7 of the film image reproducing apparatus 1.
03 or the monitor TV2, for example, as shown in FIG.
This is performed by displaying the rewind mark FR or the fast-forward mark FF shown in FIG.

Subsequently, the film 11 is rewound at a high speed. During this rewind, a frame F for which frame information needs to be rewritten is detected, and the magnetic recording sections 117A and 117A corresponding to the frame F are detected.
Only the frame information of 117B is rewritten (# 32
7 to # 333). When the rewriting of the frame information is completed (#
(YES in 333), the leader unit information is continuously recorded in the magnetic recording units 116A and 116B of the film leader unit 11A (# 335), and when the film 11 is completely stored in the film cartridge 9, the rewinding process is stopped. (#
337).

Subsequently, after the light-shielding cover 98 of the film cartridge 9 is closed (# 339) and the alignment mark 93 is set at a predetermined position ("EXPOSED" position) (# 341), the instruction of the eject switch 803 is issued. (# 343). The alignment mark 93 is set at the “EXPOSED” position so that when the film cartridge 9 is taken out and reloaded, it is determined that the film is not a developed film, so that reproduction cannot be performed.

Note that the set of the alignment marks 93 is as follows.
As shown in JP-A-5-313234, when the film 11 is rewound, the code of the bar code 94 is detected by the photo reflector 14, and after the film 11 is stored in the film cartridge 9, the use state of the film 11 is determined. The rotation of the spool 91 is stopped when the signal pattern of the code corresponding to the above is detected.

If the instruction is not based on the instruction from the eject switch 803 (NO in # 343), the power switch 802
Is turned off, and the process is terminated (# 345). On the other hand, if it is determined by the instruction of the eject switch 803 (#
If YES at 343), the film cartridge 9 is discharged from the film loading unit 12 (# 347). During the discharge process, a display indicating that the film is being discharged is displayed on the film image reproducing apparatus 1 and the monitor TV2.

Subsequently, after the APO timer 44 is reset, it is started (# 349). If a new film cartridge 9 is loaded before the APO timer 44 counts up (YES in # 353), the AP
After the count operation of the O timer 44 is stopped and the count value is reset (# 355), the process proceeds to # 23 (see FIG. 13), and the initialization process is performed on the film cartridge 9. On the other hand, when the APO timer 44 counts up without a new film cartridge 9 being loaded (YE at # 351).
S), after closing the feeding port 99 (# 352), the process proceeds to # 345, the power switch 802 is turned off, and the process ends.

Returning to FIG. 15, if the density difference (= | detected base density−reference base density |) is within the predetermined range ε (# 8)
3) The light emission amount of the light source is determined to be normal, and the base density taken in for checking the light source (see # 77) and the base density taken in during loading (see # 55)
Is determined (# 87), and if there is a difference in the base density (YES in # 87), the correction in the signal processing of the image signal is performed based on the base density taken in for the light source check. The value is calculated again (# 89). The processing contents of this correction value calculation are the same as the processing contents of # 57. If there is no difference between the base densities (NO in # 87), the calculation processing of the correction value is not performed.

Subsequently, it is determined whether or not information relating to the base density and the exposure is recorded in the data memory 43 (FIG. 16, # 91). If the base density or the like has not been recorded (NO in # 91), the film images of each frame F are sequentially processed in the direction from the last frame F to the top frame F by the processes of # 93 to # 111 by the imaging method for a multi-image. The captured image is captured (captured as a reduced image) (# 99), and the captured image is sequentially reproduced on the monitor TV2 (# 105). Tv) and WB adjustment value (amplifier gain G for R and B colors)
R, GB) are calculated (# 101), and the calculation result is sequentially recorded on the magnetic recording units 117A, 117B of the film 11 (# 111).

When the recording of the exposure value and the WB adjustment value for the film image of the top frame F is completed (# 11)
1 and YES), the magnetic recording section 1 of the film reader section 11A.
The information such as the base density is recorded on 16A and 116B (# 113), and the feed motor M is driven in reverse rotation (film 11).
Is stopped (# 115), and the initialization processing ends.

The above exposure value and WB adjustment value are calculated by the following equation (1), and the calculation results Tv0, GR0, G
B0 is recorded on the film 11.

[0156]

Exposure value (exposure time) Tv0 = A / G0 WB gain of R color GR0 = G0 / R0 WB gain of color B GB0 = G0 / B0, where A: constant G0: base density of G color B0: Average value of base density of B color.

The captured image of each frame F is reproduced in addition to the currently reproduced multi-image for each image pickup.

FIG. 29 shows a display example of a multi-image displayed on the monitor TV2. The figure shows a multi-display of film images G1 to G24 of 24 frames in an array pattern of 4 rows and 6 columns, and is a display example of a multi image when film images G24 to G16 of 9 frames are read. is there. Since the film images are read in the direction from the last frame F to the top frame F, each of the film images G24 to G24
16 are (1, 1), (1, 2), ..., (2,
It is arranged at the position 3).

The tenth and subsequent films G15, G14,
Are sequentially arranged at the positions (2, 4), (2, 5),... Of the multi image shown in FIG. 29 and displayed on the monitor TV2 each time an image is taken. When the film image of the top frame F is captured, the 24 film images G24 to G24 are output.
A multi-image in which G1 is arranged in an arrangement pattern of 4 rows and 6 columns is displayed on the monitor TV2.

Referring back to FIG. 16, if the base density and the like have been recorded (YES in # 91), the film images of each frame F are sequentially processed in the direction from the last frame F to the top frame F by the processes of # 117 to # 131. The image is picked up (taken as a reduced image) by the image pickup method for multi-image (# 123), and the picked-up image is sequentially reproduced on the monitor TV2 (# 119). # 11
In the processes of 7 to # 131, since the exposure value and the WB adjustment value for imaging at the time of the main reproduction have already been recorded, these calculations are not performed.

When the display of the film image of the top frame F is completed (YES in # 131), the reverse drive of the feeding motor M (rewinding of the film 11) is stopped (# 11).
5), the initialization process ends.

In the above embodiment, after the loading of the film 11 is completed, the film 11 is fed to the film end portion 11C to read the film information.
At the time of rewinding the film 11, a film image of each frame F is taken and a multi image is displayed (# 99,
(See # 105, # 123, and # 127). When the film information is read, a film image of each frame F may be captured at the same time, and the captured image may be multi-displayed.

FIGS. 17 and 18 are flowcharts for displaying the film image of each frame F in a multi-display manner when reading the film information.

FIG. 17 is a diagram showing a case where # 67 and # 6 in FIG.
A multi-image imaging process (# 68) is added between 9 and
An image display process (# 70) for combining and displaying a film image captured between 69 and # 71 on a multi-image is added. On the other hand, FIG.
And the image display processing of # 127 is deleted, and # 111 and # 127 are deleted.
Image display stop processing between # 113 and immediately after (# 1)
12, # 132). The deletion of the image display processing and the addition of the image display stop processing in FIG.
This is based on the fact that an image display process has been added to # 70.

According to the flowcharts of FIGS. 17 and 18, after the loading of the film 11 is completed, the film 11 is continuously wound up, the film information corresponding to each frame F is read, and the film image of each frame F is read. The images are picked up by the multi-image pick-up method, and the picked-up images are combined with the multi-images and sequentially displayed on the monitor TV 2 (# 68 to # 71).

The multi-image in this case is displayed in the same manner as the multi-image shown in FIG. 29. However, since the imaging order of each frame F is reversed from that in the flowchart of FIG. The order of arrangement of G24 is opposite to that of FIG.

When the film 11 is wound up to the film end portion 11C and the imaging of the last frame F is completed (# 71)
YES), 24 film images G are displayed on the monitor TV2.
1 to G24 are (1, 1), (1, 2),.
The multi images arranged at the positions (4, 5) and (4, 6) are displayed on the monitor TV2. The display of the multi-image is performed by rewinding the film 11 while exposing the exposure value of each frame F and W
The calculation is continued while the calculation of the B correction value is being performed, and when the calculation process is completed (YES in # 111 or # 131),
It is stopped (# 112 or # 132).

In this embodiment, when the film 11 is wound up, multi-images are sequentially displayed on the display screen 3 of the monitor TV 2, so that nothing is displayed on the monitor TV 2 for a while after the initialization process is started, or the display contents are not displayed. The discomfort of the user due to the fact that does not change is reduced. In addition, since the arrangement order of the film images of each frame F of the multi-image is in the photographing order, there is no discomfort with the displayed multi-image.

In the flowchart of FIG. 17, the multi-images generated each time a film image of each frame F is captured are sequentially displayed on the monitor TV2. (The winding and rewinding periods of the film 11) may be displayed on average. By doing so, the rewinding period of the film 11 (# 9
3 to # 111 or # 117 to # 131)
Since the content of the multi-image displayed on the monitor 2 changes, the user's discomfort due to the display content of the monitor TV2 not changing is further reduced.

Next, the reproduction process of the film image will be described. Here, a case where the number of reproduced frames of the film 11 is 24 will be described as an example.

FIGS. 21 and 22 are main flow charts showing the reproduction process of the film image.

First, the base density of the film 11 is taken in (# 201). This base density is captured by capturing an unexposed area between frames or an unexposed area above and below a piece. Subsequently, the exposure value and the WB adjustment value calculated during the base density and initialization processing (FIG. 16)
The exposure value and the WB correction value for each frame F are calculated from # 101 and # 109) (# 203).

The base densities of the R, G, and B colors captured in # 201 are r1, g1, and b1, and the base densities of the R, G, and B colors captured during the initialization process (see # 55 in FIG. 14). ) Is r0, g0, b0, the exposure value Tv1 and the WB correction value (the WB gain GR1 of R, the WB gain GB1 of B) are calculated by the following equation (2).

[0174]

Tv1 = Tv0 · (g0 / g1) GR1 = GR0 · (g0 / g1) · (r0 / r1) GB1 = GB0 · (g0 / g1) · (b0 / b1)

It should be noted that the exposure values Tv0, Tv0,
When the WB correction values GR0 and GB0 are calculated and are recorded on the magnetic recording units 116A, 116B, 117A and 117B on the film 11, the exposure values Tv0, WB correction values GR0 and GB0 read from the film 11 are calculated. From the base densities r1, g1, and b1, a suitable exposure value Tv1, a WB correction value GR1, and a WB correction value at the time of capturing an image for reproduction are given by the above Expression 2.
GB1 is calculated.

Subsequently, the type of the film 11 is determined (# 205). There are two types of cameras: a system in which a film is wound up by one frame each time a photograph is taken and a photograph is taken in order from the first frame of the film to the rear (hereinafter referred to as a normal wind system). Once loaded, the film is once wound up to the last frame position, and each time a picture is taken, the film is rewound one frame at a time, and a picture is taken in order from the last frame of the film in the forward direction (hereinafter referred to as pre-winding). System).

A photographed film by the normal wind method (hereinafter referred to as a normal wind film) is shown in FIG.
As shown at 0, the oldest film image G1 is recorded on the first frame F of the film 11, and the newest film image G24 is recorded on the last frame F. As shown in FIG. 31, in a film that has been photographed by the prewind method (hereinafter, referred to as a prewind film), the newest film image G24 is recorded on the first frame F of the film 11, and the oldest film image G1 is recorded on the last frame F. Is recorded.

The type of the film is determined from the magnetic information read from the film 11 by the control unit 47. For example, the magnetic recording unit 116 of the film reader unit 11A
If the information about the film type is directly recorded in A and 116B, it is determined from the magnetic information. If the information about the film type is not directly recorded,
It is indirectly determined from the photographing date recorded in the magnetic recording units 117A and 117B corresponding to each frame F.

If the film 11 is a normal wind film, the first frame F to be reproduced (the frame F which is not exposed)
The film 11 is wound up to the shooting start position of the film image (the detection position of the hole 111 indicating the leading end position of the frame F) (the loop of # 207 to # 211), and the shooting conditions for the film image are set (# 213).

The photographing conditions include, for example, exposure level, W
B adjustment value, γ correction value, vertical / horizontal conversion condition, trimming condition,
There are resolution information, magnification of the optical system, etc., but here, unset conditions are set.

Subsequently, based on the set photographing conditions, the amount of light emitted from the light source 191, the aperture value of the iris 22, the exposure time (shutter speed Tv) of the CCD 23, the WB gain in the analog processing unit 24, etc. The operation condition is set (# 215).

Subsequently, low-speed feeding of the film 11 is started, and imaging of a film image for reproduction is started (# 21).
7). When a film image is reproduced at a high-vision aspect ratio, a reading scan is started at a timing when the leading end position of the image is fed to the imaging position of the CCD 23,
The reading scan is completed at the timing when the rear end position of the image passes through the imaging position of the CCD 23.

For this reason, a time lag is provided between the start timing of the feeding of the film 11 and the start timing of the scanning for reading the film image in order to adjust the stability of the feeding speed and other conditions. "REA" indicating to the monitor TV2 that the scan start is being prepared.
"DY" is displayed (# 219, # 221).

The start timing of the reading scan is determined by detecting a predetermined elapsed time from the start timing of feeding the film 11, and by detecting a hole 111 indicating the leading end position of the film image.
And the detection of a predetermined feed amount of the film 11 is performed. Further, the reading scan may be started at a timing when the feeding speed of the film 11 reaches a predetermined low speed.

Further, during the preparation for the start of the reading scan, it is determined from the format information whether or not the reproduced image is the standard size (# 223).
YES), a process of delaying the start timing of the reading scan by a predetermined time Td is performed (#).
225).

In the delay processing of the reading scan start timing, when the reproduced image is a standard size, as shown in FIG. 9B, the reproduced image GL is generated in an area where both ends of the film image are removed by d1. It is based on that. Therefore, when the feeding speed of the film 11 is v, when the reproduced image is of the standard size, the reading scan start timing is d1 / v longer than the normal reading scan start timing.
Only be delayed.

Subsequently, a film image capturing process is performed according to a flowchart of a subroutine "main scan" shown in FIG.

When the subroutine "main scan" is called, first, the number M of read lines is set (# 28).
1) The counter K for counting the number of lines actually read is reset to "0"(# 283). The number M of read lines is a predetermined number of lines corresponding to the size of the reproduced image of the frame F. When the reproduction size is the standard size, an intermediate predetermined range excluding both ends of the film image is scanned (see FIG. 9B), and the number of lines M1 corresponding to the predetermined range is set as the number of read lines. If the reproduction size is not the standard size, the entire range is scanned in the scanning direction of the film image (FIG. 9).
(See (a) and (c)), the number of lines M2 corresponding to the entire range
Is set as the number of read lines.

Subsequently, the feeding motor M is driven at a predetermined speed to feed the film 11, and the film image of the frame F is read (loop of # 283 to # 303). The film image is picked up in line units every time the film 11 is fed by one line (# 295), and this line image pickup is performed until the rear end position of the image pickup range is detected (# 301 or # 3).
(Until the result is 03 and YES).

In the main scan, an abnormality in the feeding of the film 11 is checked so that a film image is normally captured. That is, feed motor M
Is driven by a predetermined amount corresponding to one line (#
285), it is determined whether or not the film 11 has been normally fed by one line by this drive (# 287).

The above determination is made by, for example, monitoring the drive current value and load torque of the feeding motor M, or checking for a feeding failure (cutting, catching, slipping, etc.) of the film 11, and the feeding of the film 11 is normal. (# 2
(YES at 87) Imaging of one line is performed (# 29)
5) When the feeding of the film 11 is not performed normally (NO in # 287), the driving of the feeding motor M is immediately stopped (# 289), and the display unit 7 of the film image reproducing apparatus 1 displays the film. After the error display indicating the feeding abnormality is performed (# 291), the power OFF process is performed (# 29).
3). In the power-off processing, the processing is stopped, the power switch 801 is turned off, and the apparatus enters a standby state until the error content is cleared.

Subsequently, when the reproduced image is not the standard size, if the film 11 is fed to the rear end position of the imaging range of the film image (YES in # 301), the imaging operation is stopped (# 305). It is determined whether the exposure and the imaging range of the captured image are appropriate (# 307, # 309). If the exposure of the captured image or the imaging range is not appropriate (NO in # 307 or # 309), an error display indicating an abnormal reading of the film image is performed on the display unit 7 of the film image reproducing apparatus 1 (# 311) Then, the flow shifts to # 213 again to read the film image of the frame F, and if the exposure or the imaging range of the captured image is appropriate (# 307 and # 3)
09 and YES), and returns.

When the reproduced image has the standard size, when the reading of the film image is completed for a predetermined number of lines M1 (YES in # 303), the imaging operation is stopped (# 31).
3) The suitability of exposure for the captured image is determined (# 315). If the exposure of the captured image is not appropriate (NO in # 315), an error display indicating an abnormal reading of the film image is displayed on the display unit 7 of the film image reproducing apparatus 1 (# 311), and then the relevant image is again displayed. The process proceeds to # 213 to read the film image of the frame F, and if the exposure of the captured image is appropriate (YES in # 315), the process returns.

Referring back to FIG. 21, when the film image capturing process is completed, the captured film image is reproduced and displayed on the monitor TV2 based on the set predetermined rendering method (# 2).
29). Subsequently, it is determined whether or not the change of the display method of the reproduced image is instructed (# 231). If the change of the display method is instructed (YES in # 231), the display method is changed based on the change. Then, the reproduced image is displayed again (# 233). On the other hand, if the change of the display method is not instructed (NO in # 231), the current reproduction display is continued.

Subsequently, it is determined whether or not the reproduced frame F is the film image G24 of the last frame (# 235). If it is not the last frame (NO in # 235), the process returns to # 207 and the next frame F The reproduction process of the film image is performed. Thereafter, the reproduction process is sequentially performed from the film image G1 of the first frame F, and when the reproduction process of the film image G24 of the last frame F is completed (YES in # 235), the film 11 is rewound by a predetermined number of frames. After that (# 237), the reproduction process ends.

In the rewinding process of the film 11 in the step # 237, the film 11 is fed in advance to a predetermined position in order to quickly search for the reproduction frame F when the reproduction process is instructed next. What to keep. The predetermined position is, for example, the reading position of the first frame, the last frame, or the center frame. In a case where the film is often reproduced from the film image G1 of the first frame F, the above-described predetermined position may be set as the first frame.
Assuming that the first frame F to be reproduced is random, the center frame position at which the average value of the access time to the first frame F is minimized may be set as the predetermined position.

If it is determined in step # 205 that the film 11 is a pre-wind film, the flow advances to step # 241 (see FIG. 22).
By executing steps 241 to # 275, the reproduction process of the film image of each frame F is performed in the same manner as the normal wind film.

In the prewind film, since each frame F is photographed in the direction from the rear end to the front end of the film 11, the last frame F at the rear end of the film 11 (the first frame F to be reproduced). Is fed at a high speed to the reading position (# 24).
1). Then, the film images G1, G2,..., G24 of each frame F are sequentially reproduced while the film 11 is fed to the leading end side (# 241 to # 275), and the leading frame F (the last film image G24 is photographed). When the reproduction process of the currently loaded frame F) ends (YES in # 267), the film 11 is rewound by a predetermined number of frames (# 275), and then the reproduction process ends.

In the main scan of each frame F, when the positioning of the film image reading position is completed, the frame F
Is determined to be a frame to be reproduced based on whether or not the film image is an unexposed frame. In the case of a pre-wind film, the last frame F (first film image G1
It is considered that it is unlikely that the frame on which the image is photographed) is not exposed. Therefore, it is determined whether or not the second frame F (the frame on which the film image G2 is photographed) is an unexposed frame. I have to.

That is, in the reproduction processing of the normal wind film shown in FIG.
After the position of the reading position of the frame where (1) is photographed, the unexposed frame can be determined after the end of the reading position determination (# 209), and then the unexposed frame determination process (# 2).
11), but in the prewind film reproduction process shown in FIG.
After step 243), the unexposed frame discriminating process is not inserted, and after the process of positioning the next frame (# 271), the unexposed frame discriminating process (# 273) is inserted.

FIGS. 32A and 32B show the feed control of the film in the reproduction process. FIG. 32A shows the feed control for the normal wind film, and FIG. 32B shows the feed control for the pre-wind film. FIG.

In the figure, a thin arrow Q1 indicates the scanning direction of the film image in the main scan, a thick arrow Q0 indicates the feeding of the film 11 from the first frame to the last frame, and an arrow Q2 indicates the frame. 11 between the film and the piece
Is shown. In addition, the circle numbers attached to the arrows Q1 and Q2 indicate the order of the main scan (the order of reading the film images). Since the feed of the film 11 indicated by arrows Q0 and Q2 is a feed for searching the reading position of each frame F, the feed is performed at a higher speed than in the main scan indicated by arrow Q1.

In the case of a normal wind film, film images G1, G2,... G24 are sequentially taken while the film 11 is being rewound from the state where the film 11 is rewound, and are reproduced and displayed on the monitor TV2.
As shown in (a), the film 11 is simply fed in the winding direction.

On the other hand, in the case of a pre-wind film, the film images G1, G2,... Are arranged in the direction from the film end 11C to the film reader 11A. Is wound up to the reading position of the film image G1 at a high speed. Thereafter, the film 11 is fully scanned in the winding direction to read the film image G1, and the film image G1 is reproduced and displayed. When the reproduction display of the film image G1 ends,
After rewinding the film 11 at a high speed to the reading position of the film image G2, the feeding direction of the film 11 is reversed, and the film 11 is fully scanned in the winding direction to perform the film image G.
1 and the film image G1 is reproduced and displayed.

Thereafter, the film images G2 and G are repeatedly fed while repeating the high-speed feeding in the rewinding direction for locating the reading position of the film image and the low-speed feeding in the winding direction for the main scan.
3,... G24 are imaged and reproduced and displayed. That is, in the case of a prewind film, the film 11 is fed in the rewinding direction while reciprocating.

The above-described reproduction processing is for the case where the photographed frames F are reproduced in order according to a predetermined reproduction order. The operator searches the photographed contents of the film 11 and selectively selects a desired frame F. You may want to play back.

Next, reproduction control for selectively reproducing and displaying a desired frame F will be described with reference to the flow chart of “frame selection” shown in FIGS. 25 and 26.

The reproduction process for selectively reproducing and displaying a desired frame F (hereinafter referred to as a retrieval reproduction process) is performed in a predetermined retrieval mode. For example, when the retrieval mode is set by the mode switch 806, "Frame selection"
The reproduction process is performed according to the flowchart of FIG.

In the "frame selection" flowchart, it is checked whether the fast-forward switch 816 or the rewind switch 813 is ON (pressed) (# 361, # 363). In the search / reproduction process, the fast-forward switch 816 and the rewind switch 813 are switches for instructing the search direction of the frame F photographed on the film 11.

If the fast-forward switch 816 is ON (YES in # 361), the film 11 is wound up to position the reading position of the next frame F (# 363). An image is captured (# 36
7), the captured image is reproduced and displayed on the monitor TV2 (#
369). Since the first playback frame indicates the search start frame, a normal playback image is displayed on the monitor TV2 as shown in FIG. In the figure, A indicates a frame number, and B indicates information such as a shooting date and time and a title.

Subsequently, it is determined whether or not the ON state of the fast-forward switch 816 is continued (# 371). If the fast-forward switch 816 is OFF (# 371: N)
O), proceeding to # 363. O of fast-forward switch 816
If the N state is continued (YES in # 371), the film 11 is wound up at a quasi-high speed (roughly scanned at a quasi-high speed) to capture a film image of the next frame F, and the captured image is It is reproduced and displayed on the monitor TV2 (# 373 to # 3)
77). Then, while the fast-forward switch 816 remains ON, the film image of the next frame F is sequentially captured in the frame order, and the captured image is reproduced and displayed on the monitor TV2 (loop of # 375 to # 379). .

[0212] The above rough scan is for capturing a film image for multiple images. Therefore, “sub-high speed” means that the speed is higher than the speed of the film 11 in the main scan, but lower than the normal speed of winding / rewinding.

Further, as described above, since the image captured for the multi-image is captured by thinning out the normal reproduced image (see FIG. 11), the display screen 3 of the monitor TV2 is displayed as shown in FIG. As shown, an image C having a size smaller than the normal reproduced image is reproduced. Note that, in the figure, A is a frame number.

The second and subsequent reproduction displays are performed using images captured for multi-images, because the reproduced images are images for retrieval and do not require high image quality like ordinary reproduced images. . Also, the reason that the captured image is not enlarged and displayed to the size of the reproduced image is that the film image is captured at a low resolution by the interlaced scan. And
This is because the operator may feel uncomfortable or uncomfortable.

When the fast-forward switch 816 is released from the ON state during the search / reproduction process (YES in # 379), the feeding of the film 11 is stopped (# 381), and the frame F at the stop position is stopped.
To display the film image of the frame F as a normal reproduced image.
After the position of the reading position of the film image is determined (#
383), and returns to # 367. The film image of the frame F at the stop position is displayed as a normal reproduced image because the frame F indicates the frame to be searched.

In the “frame selection” flowchart, the rewind switch 813 is turned on (pressed).
Or the rewind switch 813 is
When N is reached (YES in # 363), if the frame information needs to be rewritten, the frame information of the frame F is simultaneously rewritten during the rough scan (# 385, # 38).
7, # 401, and # 403), except that the search and reproduction process is performed in the same procedure as when the fast forward switch 816 is pressed (# 385 to # 41).
1). That is, each step of # 391 to # 399 is
Corresponding to each of steps # 367 to # 375,
Each step of # 411 corresponds to each step of # 377 to # 383.

Therefore, when the rewind switch 813 is turned ON, it is determined whether or not frame information needs to be rewritten for the search start frame F (# 385). If (YES in # 385), the frame information is rewritten while the film 11 is rewound to the position where the film image of the search start frame F is read (# 387). Then, the film image of the search start frame F is captured as a normal reproduced image by the main scan,
The captured image is reproduced and displayed on the monitor TV2 (# 39)
1, # 393).

For the second and subsequent search frames F,
When the rough scan of the film image of each frame F is started (# 399), it is determined whether or not frame information needs to be rewritten for the frame F (# 401), and the frame information needs to be rewritten. Then (YE in # 401
S), the frame information is simultaneously rewritten while the rough scan is performed (# 403). And each piece F
With respect to the film image of (1), an image captured for multi-image by rough scan is reproduced and displayed on the monitor TV2 (# 399 to # 405).

In the rewind direction search of the reproduction frame F, unlike the rewind direction search, the film image of each frame F is scanned from the rear end to the front end and taken. This is because the film image of each frame F is scanned from the front end to the rear end in the same manner as in the search in the winding direction.
The rewinding of the film 11 for locating the reading position of the film image and the winding of the film 11 for capturing the film image of each frame F are alternately performed, and the search and reproduction processing in the rewinding direction is performed. This is because the processing is significantly slower than the search and reproduction processing in the direction.

In the rewinding direction search / reproduction processing, the scanning direction for writing frame information on the film 11 matches, and in the rough scan of the film image of each frame F, the film 11 Since the paper is fed at substantially the same speed as the feeding speed at the time of scanning, the frame information rewriting processing required at the time of the rough scan is performed to increase the efficiency and speed of the processing.

In the winding control of the film 11, the inertia of the driving motor M and the feeding mechanism causes the film 1 to be lifted.
Film 1 is wound up more than necessary from the end position.
1 may be damaged. Therefore, in the winding control of the film 11, the driving of the drive motor M is stopped before the film 11 is completely pulled out from the film cartridge 9, and the film 11 is not further wound up after the film 11 is completely pulled out from the film cartridge 9. You need to do that.

In this embodiment, the hole 115 indicating the rear end position of the film end portion 11C is detected, and the drive motor M is stopped based on this detection.

The stop control of the drive motor M is performed according to the flow chart of "end detection" in FIG.

FIG. 27 is a flow chart of the "end detection".
The distance between the hole 115 indicating the rear end position and the hole 115 indicating the rear end position is shorter than the distance between the hole 111 indicating the front end position and the hole 112 indicating the rear end position provided for each piece F. The film 11 is detected while detecting the feeding time T between the position and the rear end position.
And the feed time T is the feed time T detected last time.
If it becomes shorter, it is determined that the feeding time T is the time during which the film is fed between the leading end position and the trailing end position of the film end portion 11C, and the hole 115 indicating the trailing end position of the film end portion 11C is detected. Like that.

That is, it is determined whether or not the feeding speed of the film 11 is low (# 421). If the feeding speed is low (YES in # 421), the process proceeds to # 423, and
At 423 to # 439, the end detection process of the film 11 according to the low-speed feeding is performed, and if the feeding speed is high (# 42).
(1; NO), the process proceeds to # 439, and in # 439 to # 455, the end detection process of the film 11 corresponding to the high-speed feeding is performed.

The end detection process for the low-speed feeding and the end detection process for the high-speed feeding include the reference feeding times Tr1 and Tr1 set in the first time memories T _n-1 and T _m-1.
2 are different, and the steps # 423 to # 439 respectively correspond to the steps # 439 to # 455, and the basic processing procedure is the same. Perform only processing.

The reference feeding time Tr1, Tr2
Is set as the feed time T0 because there is no feed time T0 for the preceding frame F to be compared with the actually measured feed time T1 for the first piece F.

When the feeding speed of the film 11 is low, the preset reference feeding time Tr1 is set in the first time memory T _n-1 of the memory 362 (# 423). Subsequently, a hole 11 indicating the tip position of the first piece F after the start of winding.
When 1 is detected (YES in # 425), the timer T3
(FIG. 4, corresponding to the timer 361) starts counting (# 427), and when the hole 112 indicating the rear end position of the first frame F is detected (YES in # 429), the counting of the timer T3 is stopped. (# 431), the count time (feed time) T1 is stored in the second-time memory T _n of the memory 362 (# 433).

Subsequently, the count time T1 stored in the _first time memory T _n-1 is compared with the reference feed time Tr1 stored in the second time memory T _n , and the count time T1 is determined. It is determined whether or not the time is very small as compared with the reference feeding time Tr1 (# 435).
1 is much smaller than the reference feed time Tr1 (#
(YES in 435), it is determined that the hole detected in # 427 is the hole 115 indicating the rear end position of the film end portion 11C, and the driving of the drive motor M is stopped (# 439).

The count time T1 is equal to the reference feed time Tr.
If it is substantially the same as 1 (NO in # 435), the content of the first time memory T _n-1 is rewritten to the count time T1 (# 437), and the process returns to # 425 and proceeds to # 425.
~ # 433 in feed time T2 for the second frame F is counted, the content of the second-time memory T _n is rewritten by the count result.

Subsequently, the feed time T2 for the current frame F stored in the _first time memory T _n-1 and the second
Time Memory T _n feeding time for frame F before stored in comparing the T1, feed time T2 is the feeding time T1
It is determined whether it is very small compared to (# 43)
5).

If the feeding time T2 is much smaller than the feeding time T1 (YES in # 435), it is determined that the hole detected in # 427 is the hole 115 indicating the rear end position of the film end portion 11C. Then, the driving of the drive motor M is stopped (# 439), and if the feeding time T2 is substantially the same as the feeding time T1 (NO in # 435), the contents of the _first time memory T _n-1 are read. Is rewritten to the count time T2 (# 437), and the process returns to # 425.

[0233] Hereinafter, compared with the feed time T _n-1 for the previous frame F and the feed time T _n for the current frame F each for detecting a feed time T _n of each frame F, the current supply if very small transmission time T _n is compared to T _n-1 the previous feed time (YES in # 435), determines that the hole 115 that indicates the rear end position of the film end portion 11C is detected Then, the drive of the drive motor M is stopped (# 439).

In this embodiment, the film end portion 1
A hole 115 indicating the rear end position of 1C is detected, and the drive motor M is stopped based on this detection. For example, a mark indicating the film end portion 11C is attached to the film 11, and this mark is detected. Alternatively, the drive motor M may be stopped. Further, the frame number assigned to each frame F is detected, and if the frame number exceeds the frame F having the largest frame number, the drive motor M may be stopped by judging that the film end portion 11C has been reached and the drive motor M may be stopped. The drive motor M may be stopped when the withdrawal amount is detected and the film 11 is withdrawn by a predetermined amount or more.
