DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an imaging device,
In particular, the present invention relates to a camera for both silver halide photography and electronic imaging having both functions of a silver halide photography device and an electronic imaging device.

[0002]

2. Description of the Related Art Conventionally, there have been proposed various techniques relating to a silver halide photographing and electronic image taking camera, in which a subject image is exposed to a silver halide film and the subject image photoelectrically converted by an electronic image pickup device is stored in a memory. .

In general, in a binocular silver halide photography and electronic imaging camera, a roll film J135 or an IX240 cartridge film is usually used as a silver halide film used for silver halide photography. But 36mm x 24mm and 27.4mm respectively
× 15.6 mm in size.

On the other hand, the image size of an image pickup device for electronic image pickup is as follows when a 1/2 inch CCD is used.
It is 6.4 mm x 4.8 mm.

As described above, since the sizes of the two images are different from each other, the photographing optical system for silver halide photography having a large image size is considerably larger than the optical system for electronic imaging. Here, when the silver halide imaging optical system and the electronic imaging optical system are arranged, an arrangement in which a light beam incident on the electronic imaging optical system is not blocked by a lens barrel for silver halide imaging including a large silver halide imaging optical system. is necessary.

In view of the above, various proposals have been made.

For example, Japanese Patent Application Laid-Open No. Sho 62-61036 discloses a technique relating to a silver halide photography and electronic imaging camera in which light emitted from a pentaprism of a single-lens reflex camera is divided by a half mirror and guided to an electronic imaging device. Proposed.

In this system, there is no parallax between the photographing optical system and the image pickup optical system, but there is a problem that the amount of light guided to the photographing means and the image pickup means is reduced because the light beam is divided into two.

Further, Japanese Patent Application Laid-Open No. 10-104736 proposes a technique relating to a binocular silver salt photographing and electronic imaging camera.

In the case of this twin-lens camera for both silver halide photography and electronic imaging, it is disadvantageous in comparison with the single-lens system from the viewpoint of parallax, but in terms of light quantity, it is a half mirror for dividing the optical path. Was advantageous because it was unnecessary.

[0012]

However, in the technique disclosed in Japanese Patent Application Laid-Open No. H10-104736, since the arrangement is as described above, it is necessary to provide an electronic imaging optical system inside the strobe / pop-up section. Therefore, the size of the strobe / pop-up unit becomes large. In addition, the number of wires from the strobe pop-up to the inside of the body increases, which causes problems such as difficulty in ensuring a smooth up-down operation of the strobe pop-up portion.

Next, the configuration of the control system of the camera will be described in detail.

A central processing unit (CP) for overall control
U; Central Processing Unit) 38, via a bus, a signal processing circuit 33, an image synthesizing circuit 34, a dynamic R
AM (hereinafter referred to as DRAM) 36, flash memory 37, switch input unit 39, film drive circuit 48,
The shutter drive circuit 49, the mirror drive circuit 45, the AF line sensor drive circuit 44, the focus drive circuit 24, the aperture drive circuit 25, and the zoom drive circuit 26 are communicably connected.

The focus drive circuit 24 drives the lens group 21 in the optical axis direction to perform focus. The aperture drive circuit 25 is for controlling the opening and closing drive of the aperture mechanism 22. The zoom drive circuit 26 is for driving the lens group 23 for zooming in the optical axis direction to perform zooming.

Although not shown, the switch input section 39 is a first release switch which is turned on by a first stroke of a release button, and is turned on by a second stroke.
A 2nd release switch to be in the N state, a power switch (not shown), a zoom switch (not shown), a mode changeover switch for switching between an electronic photographing mode and a silver halide photographing mode (not shown), and a TELE switch for performing zooming (driven to a long focal length side) Switch), a WIDE switch (an operation switch for driving to the short focus side), and the like.

In such a configuration, during silver halide photography, the first release is set to O by the switch input section 39.
N, the subject light passes through the silver halide photographing optical system 20,
After being transmitted through the movable mirror 40 and reflected by the sub-mirror 41, the light is received by the AF line sensor 43 via the separator optical system 42. The CPU 38 obtains the AF sensor data of the AF line sensor 43 via the AF line sensor driving circuit 44, obtains a two-image interval from the data, or obtains a driving amount of a lens group for focusing based on the two-image interval. Is calculated, the drive control is performed, the drive control of the aperture mechanisms 22 and 30 is instructed, and the drive control of the movable mirror 40 is performed via the mirror drive circuit 45. At this time, the subject light is reflected by the movable mirror 40 and is also guided to the photographer's eyes via the focusing mat 50, the pentagonal prism 51, and the finder eyepiece lens 52. Then, at the switch input unit 39,

This digital video signal is stored in a DRAM 3 as a high-speed writable nonvolatile memory.
6 is temporarily stored. The image synthesizing circuit 34 synthesizes the digital video signal stored in the DRAM 36 with other display information and the like, and outputs a predetermined image signal to the LCD monitor 35. LCD monitor 35
Then, a predetermined display is performed based on this image signal. The digital video signal temporarily stored in the DRAM 36 is also temporarily stored in the flash memory 37.
Generally, the flash memory 37 is electrically rewritable, and retains an electronic image even when a battery is not loaded in the camera. Therefore, the flash memory 37 is suitable for storing an electronic image.

Hereinafter, referring to the flowchart of FIG.
The operation of the camera according to the first embodiment will be described in detail.

In this sequence, the CPU 38 determines whether or not the power switch inside the switch input section 39 is turned on (step S1). If the power switch is not turned on, the CPU 38 gives an instruction to turn off the display on the LCD monitor 35 (step S2), and executes a predetermined standby process 1 (step S3). In the standby process 1, before the operation of the CPU 38 is stopped, conditions are set for the CPU 38 to start the operation again after the stop. Here, in the standby processing 1, the operation is set to start when the power switch is turned on. Then, the operation of the CPU 38 is stopped. When the standby state is set, the operation is executed again from the step S1.

On the other hand, if it is determined in step S1 that the power switch is ON, the CPU 38
Is a lens group 21 via a focusing drive circuit 24.
Is driven from the retracted position (not shown) to the wide position by driving the lens group 23 via the zoom drive circuit 26 (step S4), and then the counting of the built-in timer of the CPU 38 is started (step S5). This timer is
This counter counts up every predetermined time, and starts counting after the count value is cleared (reset) to zero.

Subsequently, the CPU 38 operates the switch input unit 3
The state of the first release switch inside 9 is monitored (step S6), and if the switch is turned on, photometry is performed by the area sensor 31 (step S7).
When the photometry is completed, a subject brightness value is output from the area sensor drive circuit 32, and the value is input to the CPU 38 via the signal processing circuit 33.

Next, the CPU 38 determines the interval between the two images based on the signal input via the AF line sensor drive circuit 44, and operates the photographing lenses (lens groups 21, 23) for driving to the in-focus position. Calculate the driving amount data. CPU3
Reference numeral 8 denotes a lens group 21 for focusing through a focusing driving circuit 24 based on the driving amount data.
23 is driven (step S8).

Subsequently, based on the subject luminance value, a program diagram (not shown), and the film sensitivity detected by a film sensitivity detection circuit (not shown), the aperture value of the aperture mechanism 22 and the shutter for obtaining the proper exposure are obtained. The speed is calculated (step S9). Then, a subroutine "exposure sequence", which will be described in detail later, is executed, and image pickup by the area sensor 31 and exposure to the film 46 are performed (step S1).
0). After performing a series of processes in this way, the process returns to step S5.

On the other hand, if the first release switch is not turned on in step S6, the CPU 38
Determines again whether the power switch is ON (step S11). If the power switch has not been turned on, the process returns to step S2, and
The above operation is performed. On the other hand, the power switch
If N, the status of the TELE switch for zooming inside the switch input unit 39 is monitored (step S12). If the switch is ON, the status is transmitted via the zooming drive circuit 26. The TELE drive, which is zooming to the long focal length side, is performed (step S
13).

If the TELE switch is not turned on in step S12, the state of the WIDE switch for zooming inside the switch input section 39 is monitored (step S14), and the switch is turned on. If there is, the WIDE drive for zooming to the short focus side is performed via the zoom drive circuit 26 (step S
15). After the processing in step S13, step S
When it is determined in step 14 that the WIDE switch has not been turned ON, and after the processing in step S15, the process proceeds to step S16.

When a predetermined time elapses after the timer starts counting, the timer overflows. In step S16, it is determined whether or not the timer has overflowed.
Returning to step S6, the above-described processing is repeated, and if overflow has occurred, the processing proceeds to step S17 and subsequent steps. The reason why such a process is employed is that if no operation member of the camera is used at all even after a predetermined time has elapsed, the CPU 38 is set in a standby state for low energy consumption.

That is, when the timer overflows (step S16), an instruction to turn off the display is given to the LCD monitor 35 (step S17), and the standby process 2 is executed (step S18). In this standby process 2, as in step S3 described above, the CPU 3
Before the operation of Step 8 is stopped, the CPU 38 sets conditions for restarting the operation after the stop. That is, in the standby process 2, the operation is set to be started by a change in the state of an operation switch such as a first release switch, a TELE switch, and a WIDE switch. Thus, C
The operation of the PU 38 is stopped. When the standby state is released, the above-described processing is executed again from step S5.

Next, the operation of the subroutine "exposure sequence" executed in step S10 of FIG. 3 will be described in detail with reference to the flowchart of FIG.

In this exposure sequence, first, the CPU
38 sends a control signal to the signal processing circuit 33 to turn off the LCD monitor 35 (step S50). Subsequently, the state of the second release switch included in the switch input unit 39 is monitored (step S51). If the switch is not turned on, the state of the first release switch is monitored again (step S52). The process returns to step S51, and returns if not turned on.

If it is determined in step S51 that the second release switch 51 is ON, then it is determined whether the digital photographing mode is set or the silver halide digital simultaneous photographing mode is set (step S5).
3). Here, when the digital photographing mode is set, an image is taken using the area sensor 31 (step S54), and the signal processing circuit 33 receives the signal from the area sensor 31 via the area sensor drive circuit 32. An analog video signal is captured and converted into a digital video signal (step S55). Then, after the signal processing circuit 33 performs predetermined signal processing (such as color conversion), the digital video signal is transferred to the DRAM 36 and stored therein (step S5).
6), and proceed to the processing after step S66.

On the other hand, if it is determined in step S53 that the digital imaging mode is not set, that is, the digital camera is set to the silver halide digital simultaneous imaging mode, the aperture driving circuit 2
5, the aperture mechanism 22 is narrowed down to the set aperture value (step S57).
The movable mirror 40 is retracted outside the photographing optical path (step S5).
8) Imaging is performed by the area sensor 31 (step S59), and the shutter 47 is driven via the shutter drive circuit 49 to control the shutter time to be the set shutter time (step S60).

Subsequently, the signal processing circuit 33 takes in the analog video signal from the area sensor 31 via the area sensor drive circuit 32 and converts it into a digital video signal (step S61). Further, the signal processing circuit 33
Perform predetermined signal processing (such as color conversion). And DRAM
The digital video signal is transferred to and stored in 36 (step S62). Then, the retracted movable mirror 40 is returned to the position in the photographing optical path (step S63), the aperture mechanism 22 in the aperture stop state is returned to the open position (step S64), and the film is driven via the film drive circuit 48. (Step S65), and the process proceeds to step S66 and subsequent steps.

In step S66, the captured image is displayed on the LCD monitor 35. And the DRAM 36
The digital video data stored above is subjected to compression processing (step S67), the compressed digital video data is stored in the flash memory 37 (step S67), and the process returns to the main sequence.

According to the first embodiment described above,
An arrangement of an optical system without vignetting can be realized between the silver halide photographing optical system and the digital imaging optical system, and an arrangement of an optical system without parallax can be realized between both optical systems.

Next, a second embodiment of the present invention will be described.

Further, an entrance window 121 of an optical finder is provided at a predetermined position in the upper center of the front. Other configurations are the same as those in FIG. 1, and thus detailed description is omitted.

Further, as shown in FIG. 5B, the layout of the eyepiece 7 of the optical viewfinder is different from that of FIG. That is, in this embodiment, the eyepiece 7 is provided at a predetermined position on the upper left side of the rear surface.

FIG. 6 is a diagram showing a detailed configuration of the camera according to the second embodiment.

Here, only the configuration different from that in FIG. 5 will be described in detail, and the common configuration will be denoted by the same reference numeral and detailed description will be omitted.

The distance measuring section 110 performs triangulation, which will be described later in detail.

In the second embodiment, since the digital image pickup unit and the strobe light emitting unit are arranged close to the left shoulder of the camera, a finger is applied to the window member 120 of the strobe light unit. The detection can be detected based on information from the digital imaging unit, and a warning can be issued.

Here, FIG. 7A shows a case where the strobe light emitting unit is hidden by the finger of the left hand when the camera is held. In this case, the photographing cannot be performed as desired because the energy of the strobe light is not effectively used.

In this case, the video data obtained from the area sensor 31 is shown in FIG. That is, full screen 2

0).

Further, when it is determined that the timer has not overflown (step S16), an image is taken using the area sensor 31 (step S101), and a subroutine "finger holding determination" to be described later is executed. Using the video information from the sensor 31, the detection of the finger hook is performed (step S102). When it is determined that there is a fingerhold (step S103), a warning indicating the fingerhold is performed by sounding the buzzer 111 for a predetermined time (step S104).

FIG. 9 is a flowchart showing the sequence of the subroutine "judgment by finger" executed in step S102 of FIG.

In this sequence, first, the average brightness (BVA) of the entire screen 200 is obtained from the video data obtained from the area sensor 31 (step S200). Subsequently, the average luminance (BVL) of the lower designated area 203 is obtained (step S201). Then, BVL <BVA-3
In other words, if the lower average luminance BVL is three times or more darker than the average luminance BVA of the entire screen (i.e., the brightness is 1/8 or less), it is determined that the finger is present, and the finger retention flag is determined. Is set to 1 (step S203). On the other hand, BVL
If it is not BVA-3, it is determined that there is no finger touch,

According to the second embodiment described above,
Since the digital imaging unit is provided on the right shoulder (or left shoulder) of the camera, it is possible to realize an arrangement of an optical system free from vignetting between the camera and the silver halide photographing optical system with a simple configuration.

Further, since the digital image pickup section and the strobe light emitting section are provided close to each other, it is possible to detect a fingerhold using the video data from the digital image pickup section and issue a warning.

The second embodiment can be modified as follows.

That is, the same effect can be obtained by arranging the digital image pickup unit and the strobe light emitting unit side by side on the right shoulder of the camera.

Further, as shown in FIG. 10, it is a matter of course that the digital imaging section may be provided inside and the strobe light emitting section may be provided outside.

Although the buzzer sounds the warning for finger-holding, a warning display LED may be provided in the finder to display the warning. Further, the warning may be performed by detecting a fingerhold only when the strobe emits light (during darkness, when backlight is determined, or the like).

Next, a camera according to a third embodiment of the present invention will be described.

FIG. 11 is a configuration diagram of a camera according to the third embodiment.
