Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a method for confirming the expression, pose, etc. of a photographic subject at the moment the photograph is taken.

(Prior Art) As is well known, the results of photography, in other words, the quality of the subject's facial expressions and poses at the moment the photograph is taken, are generally determined by developing the film after the photograph has been taken, or by developing it. Normally, a judgment cannot be made until the film is printed on photographic paper and developed.

(Problem to be solved by the invention) Therefore, as a result of taking a matchmaking photo, not only the expression and pose at the time of the photo shoot, but also the blinking at the moment the shutter opens, or the line of sight (line of sight) changes. If something looks unnatural, try developing the film, or processing the photographic paper printed using the film, and after checking the results, try shooting again. friend.

Therefore, the inventors of the present invention simultaneously record the facial expressions and poses of the photographed subject at the moment when the camera shutter is open on another recording medium, such as a videotape, or use a polylide camera to instantly record the subject's facial expressions and poses. I tried to find a practical way to recreate the situation by taking photos and trying to recreate the situation as it was when the photo was taken.

However, the use of a videotape recorder.

A fraction of a second or a hundredth of a second when the shutter is open
It takes a lot of effort to play back a still image of a few seconds,
Also, when considering consumables for Polaroid photos,
Due to the high costs, it seems that there is currently a long way to go before these methods or means can be put to practical use.

(Means for Solving the Problems) In view of the above-mentioned circumstances, the present invention has been developed by installing the TV right camera as close as possible to the camera for photographing the person to be photographed, and by installing it facing the person to be photographed, and by operating the shutter of the camera. The video signals from the TV right camera, which are sometimes supplied to one image memory section, are processed in the image memory section by a synchronization signal from the TV right camera and a signal generated by shutter operation. The signal is digitized and stored in a semiconductor memory, the video signal stored in the semiconductor memory is read out based on the synchronization signal from the TV right camera, etc., the read video signal is converted into an analog signal, and this is supplied to the monitor TV. The image of the person to be photographed is displayed on a monitor TV, and the facial expression, pose, etc. of the person to be photographed at the time of taking the photograph are characterized in that the image is configured so that the expression, pose, etc. of the person to be photographed at the time of taking the photograph with the camera can be confirmed. This is related to the confirmation method.

(Function) In other words, when trying to photograph a subject with a camera, move the TV right camera as close as possible to this camera.
In order to obtain the same image as the camera when aiming at the same subject, the image signal from the TV, that is, the video signal, must be supplied to the monitor TV via the image memory section.

And when the camera shutter is activated.

The video signal from the TV right camera supplied to the image memory section is triggered in the memory section by a synchronization signal from the TV right camera and a signal generated by the operation of the shutter, and the video signal is digitized. The video signal stored in the semiconductor memory is read out based on a synchronization signal from the TV right camera, and the read video signal is converted into an analog signal.

This is supplied to a monitor TV, the image of the subject is projected on the monitor TV, and the camera captures the subject's facial expressions and poses at the moment the shutter is activated in order to take pictures with the camera. This can be detected and confirmed before processing the photographed film, and in some cases,
It became possible to take pictures with the camera again on the spot 0 (Example) The following is a flowchart of a confirmation device of an embodiment of the method for confirming the facial expression, pose, etc. of the photographed person at the time of photography according to the present invention. An embodiment of the present invention will be described in detail with reference to the drawings illustrated in the formula.

In the figure, 1 is a camera equipped with a shutter button 2, etc. as usual, and 3 is a synchronizer that synchronizes a flash or strobe light emitter 4 with the opening/closing operation of the shutter, and supplies a signal for operating an image memory unit 6, which will be described later. Signal distributor, 5, TV right camera 12, cathode ray tube (CRT) 13 as usual
X is the person to be photographed, and X' is an image of the person to be photographed at the moment the photograph is taken, which is displayed on the monitor TV 12 as will be described later.

By the way, the above-mentioned image memory unit 6 includes a synchronization separation circuit 7 and an A/D converter 9 to which video signals scanned by the TV right camera are simultaneously supplied. When the synchronization signal separated by the synchronization separation circuit 7 and the synchronization signal linked to the shutter operation start timing are supplied, and the signal due to the operation start is supplied, the synchronization signal and the operation start signal cause A start signal for two fields, which is a write period, is supplied to the A/D converter 9, and on the other hand, an addressing decoder signal and a video signal for two fields stored in the digital IC memory 10 are supplied to the digital IC memory 10. a memory control circuit 8 that supplies a synchronization signal for signal readout;
an A/D converter 9 that supplies a digitized video signal to the digital IC memory 10 based on the start signal supplied from the memory control circuit 8;
The digitized and supplied video signal is sequentially written to each address based on the address designation decoder signal, and the video signal for two fields is stored.

A digital IC memory 10 supplies a video signal read out based on a synchronization signal for video readout from the memory control circuit 8 to a D/A converter 11, and a digital IC memory 10 converts the video signal from the digital IC memory 10 into a D/A converter. monitor T
It is configured in a well-known manner including a D/A converter 11 and the like that supply the signal to V12.

The device for confirming facial expressions, poses, etc. of the photographed person in photography, which is an embodiment of the present invention, is configured as described above.
Now, when the camera 1 is set to face the subject On the other hand, a video signal obtained by scanning a TV camera 5 set toward the person X to be photographed is supplied to a synchronization separation circuit 7 and an A/D converter 9.

When the signal from the synchronization signal distributor 3 is supplied to the memory control circuit 8 to which only the synchronization signal is supplied from the synchronization separation circuit 7, the memory control circuit 8 enters the write period to the A/D converter 9. A start signal for two fields is supplied every time one field is scanned, and an addressing decoder signal is supplied to the digital IC memory 10.
The video signal digitized by the /D converter 9 is converted into a digital IC memo+1 based on the addressing decoder signal.
-10 addresses are sequentially written, and video signals for two fields can be stored. Further, the reading of the video signal for two fields stored in the digital IC memory 10 is performed based on a reading synchronization signal from the memory control circuit 8, and this read signal is transmitted to the D/A. D/A converted by converter 11 and sent to monitor TV1
2 and the cathode ray tube 13 of this monitor TVI 2.
, not only the facial expressions including the line of sight of the person to be photographed when the camera 1 is photographing the person to be photographed, but also the pose of the person to be photographed are all captured.

(Effects of the Invention) As is clear from the above description, according to the present invention, all the good and bad things such as the facial expressions and poses of the subject when taking pictures with the camera can be detected by developing the film loaded in the camera, Alternatively, the film can be used to print on photographic paper and then developed and processed.
