13 in the optical path of the display image, and the opening 59 is left as it is.
The light beam from the imaging monitor 13 that has passed
It is guided to the binder 51 side. This allows the finder 51 to be
It was visually displayed on the monitor 13 for photographing by peeping.
Images can be observed. The second operation in the photographing device 42 during the photographing operation
Operation of the frame memory 43 and control of the camera 45
I will explain. The photographing control unit 46 controls the release switch 8
Therefore, every time a release instruction is given and a release signal is received
To the image capturing control unit 47,
The image input to the photographing device 42 is stored in a second frame memory.
43 to be stored in a plurality of frame memories
Control. Thereby, the second frame memory 43
Indicates that multiple images will be recorded in sequence each time a release signal is input.
I will be remembered. At this time, the image capturing control unit 47
Even if shooting of the image of the previous piece has been completed in camera 45
Regardless of whether the image has been finished, the image at that time is
It is stored in the frame memory 43. Second frame memory
43, an image is temporarily stored in a plurality of frame memories.
Memory is read out and stored until the shooting is completed.
Writing is stopped, and each is kept frozen. As described above, the second frame memory is stored in a plurality of
By configuring with a frame memory,
Images for shooting as still images
Can be captured. Further, the photographing control section 46 finishes one photographing.
Every time the process is completed, a command is sent to the image reading control unit 48, and the second
The shooting stored in the frame memory 43 has not been completed.
Control to read a new image. When shooting,
The motion control unit 52 finishes capturing an image of one frame by multiple exposure.
When it is completed, the film is taken up by a winding mechanism (not shown).
Wind up pieces. At this time, the photographing control unit 46
The completion recognition unit recognizes the completion of the film winding operation.
A winding operation recognition signal is generated. Recognition of completion of hoisting operation
Then, the photographing control unit 46
Command to send the image to be shot to the next frame in the order stored.
Monitor read out from second frame memory 43
13 and shoot to execute the next frame
Monitor 13 and the rotation filter 44 to control the camera 45
To shoot. At this time, the image reading control unit 48
Represents the number of images stored in the frame memory.
For example, from the image stored first,
The data is read from the memory and output to the photographing monitor 13. As described above, the film control
Equipped with a film winding completion recognition unit that recognizes completion of winding
As a result, the image for the next frame is
The image can be projected on the photographing monitor 13. The camera drive control unit 52 includes a photographing control unit 46
Upon receiving a release signal, the shutter 50 in the camera
To control the valve. That is, the camera drive control unit 52
When a release signal is input, the shutter 50 is opened.
Then, an exposure end signal is received from the photographing control unit 46.
Then, control for closing the shutter 50 is performed. Then, the camera drive control unit 52
As soon as the printer 50 is closed, the winding of the film 19 is opened.
Start. When the film winding is completed, the photographing control unit 4
6, the completion of shooting is recognized, and the shooting of the image of the next frame is started.
Be started. As described above, the shutter is controlled by the valve to control the shutter.
The film is wound up at the same time as the
It is possible to prepare for the next frame without wasting time
Wear. When the shutter is opened for a fixed time without performing valve control
When controlling by setting the interval, variations in the exposure time
Considering the actual exposure time, add some allowance
It is necessary to make the shutter close after applying
The entire shooting time will be lengthened accordingly, but this implementation
By using valve control as in the example, each piece
The shutter is closed immediately after the end of shooting, and the film is
Winding can be started, and film winding is finished
Later, shooting of the next frame can be started immediately. When a photograph is taken by the multiple exposure method, one frame
Multiple exposures are required for shooting, for example, RGB
In the case of multiple exposure of the image of R, G, and B,
Exposure of the image to one frame of film requires three exposures
is there. Therefore, three exposure times and an additional
Long switching time is required to switch the filter
Will take. Photography of endoscope systems
In order to reduce the patient's pain,
It needs to be completed in a short time. According to the present embodiment, photographing is performed regardless of the photographing time.
Even if you are in the shadow, hold the release and hold multiple images
After the shooting of one frame, the shooting of the next
Reduces the time required for shooting with the multiple exposure method
It is possible to do. Also, in this case, the release instruction
Remove the endoscope from the body cavity before the end of imaging
And the burden on the patient can be further reduced. Also,
By controlling the camera shutter valve,
Immediately after the exposure is completed, it is possible to shift to the shooting operation of the next frame.
The photographing time can be shortened. In this embodiment, the freeze of the electronic endoscope is performed.
With the release signal generation means by the switch, the surgeon can
Release instructions can be issued immediately at hand. Note that
Use a foot switch or other
Means may be provided. As described above, according to the configuration of the fourth embodiment.
If the multi-exposure system is used,
Time can be reduced and multiple images can be
It becomes possible to shoot quickly. [Appendix] As described in detail above, the present invention
