Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is to record electronically at the same time when shooting using a silver salt film in a studio or the like.
The present invention relates to an image capturing system that facilitates mutual collation of images.

[0002]

2. Description of the Related Art Conventionally, in a studio or the like, both a film camera using a silver salt film and a video camera are aimed at a subject, and strobe light emitted for shooting by the film camera is detected, and a video signal of a field immediately after that is detected. There is known a photographing system for recording an image in a recorder connected to a video camera. This allows you to electronically record an image at the same moment as an image taken with a film camera, so that you can play back the electronically recorded image and view it before printing the image taken with the film camera. I can confirm. Therefore, you can easily check whether you closed your eyes at the moment of shooting, so you can show multiple shot images to the customer and select an image with your favorite expression, and only the selected image is displayed. It has the advantage of printing.

As a recorder used above, there is a recorder using a video floppy or a semiconductor memory.

[0004]

In the conventional photographing system described above, it is easy to select only the favorite image by looking at the electronically recorded image.
Matching which frame of the film the electronic image corresponds to requires a considerably troublesome work. When using a reversal film, it is still difficult to recognize a detailed image on a negative when using a negative film, and it is selected first after recognizing a close eye or a slight difference in facial expression. It is very troublesome to compare and collate with the electronic image. Therefore, the number of frames is decided when the person or clothes change, and there is a great risk of selecting the wrong frame.

Further, when the film is processed for development, the image corresponding to the film is separated from the recording medium on which the image is electronically recorded, which makes the collation more difficult.
I have no choice but to attach memos to films and recording media frequently, but it is troublesome and easy to forget.

[0006]

According to the present invention, there is provided a film camera for taking a picture on a silver salt film frame by frame, a flash device for emitting light by a synchronizing circuit of the film camera, and a flash unit disposed near a subject. A display that displays a predetermined identification number, a video camera that continuously captures images with a solid-state image sensor, a light receiver that receives the reflected light that is emitted by the flash device and reflected by the subject, and an image captured by the video camera And a recording device for recording an identification number on a recording medium and outputting a signal to the display device, the flash device is caused to emit light, and the subject and the identification number displayed on the display device are photographed by the film camera. When the light receiver receives the reflected light, an image captured by the video camera and an identification number are recorded on a recording medium of the recording device, It is solved by changing the identification number of the display by the signal.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an image pickup system of the present invention will be described in detail with reference to FIGS.

A first embodiment will be described with reference to FIG.

FIG. 1 is a conceptual diagram of a studio for photographing a subject 10. 11 is a film camera for photographing one frame every shutter release using a silver-halide film (hereinafter referred to as film), it may be any kind of camera began studio cameras are conventionally used in photo studio. Reference numeral 12 is a strobe as a flash device, which emits light by a synchro circuit that operates in conjunction with opening of a shutter in the film camera 11 to illuminate the subject 10. A flash bulb may be used instead of the strobe. Reference numeral 13 denotes a video camera, which continuously images the subject 10 by an internal solid-state image sensor. A recorder 14 is connected to the video camera 13 and records a field signal of an image picked up by the video camera 13 on a recording medium such as a video floppy or a semiconductor memory, and outputs a control signal to the display 15 each time recording. The display 15 is arranged near the subject 10 and is connected to the recorder 14 to display an identification number composed of numbers and symbols, and when the film camera 11 and the video camera 13 shoot, the screen on which the subject 10 is shot is displayed. An identification number is imprinted in the corner of the. 16 is the subject when the flash 12 is fired
It is a light receiver for receiving the reflected light reflected by 10.

When each device is arranged in this way and the release button 11a of the film camera 11 is pressed, the internal shutter is opened and the synchronizing circuit is turned on, so that the precharged strobe 12 emits light and the subject 10 Is photographed together with the identification number of the display 15. The video camera 13 continuously shoots the subject 10 together with the identification number of the display 15 before the film camera 11 shoots. When the light receiver 16 receives the reflected light of the strobe 12 reflected by the subject 10, the signal is recorded. The field signal from the video camera 13 immediately after the input is input to the recording medium. The recording at this time is to record the identification number together with the image. When recording on a video floppy, the method of recording a signal in which a frequency different from the image signal is modulated with digital data is specified as the DPSK method. Therefore, it is desirable to use this. When the image data is recorded in the semiconductor memory, the image data is also recorded digitally, so that the digital data of the identification number may be handled in the same manner. When recording images as digital data, the recording method is specified as a format, for example, TIF
There are such things as F, PICT, and TARGA. In these, a method of recording data attached to an image is defined, and if this is followed, versatility is maintained. However, even if it does not necessarily follow, if the image data and the accompanying data can be distinguished from each other, there is no problem with the original format.

Each time the recording machine 14 records an image, it increments the identification number by one or by a predetermined number and outputs a pulse to the display 15. The display 15 inputs the pulse and counts up the displayed identification number.

Therefore, if the display 15 is first set to the same identification number as that recorded by the recorder 14 and then photographing is started, the same identification number is always recorded on both the film and the electronic recording medium thereafter. Therefore, the collation between the film image and the electronic image can be performed very easily later.

In the shooting standby state, the signal from the video camera 13 is directly displayed on the monitor 18 as a through signal.
There, an identification number to be recorded together with the next image recording is displayed. This is the same as the display on the display 15 placed near the subject, and since the operation can be performed while confirming that they match, there is no error.

When the conversion operation of the display unit 15 is fast, the identification number changes during the exposure, and two types of numbers are overlapped and exposed. For this reason, the pulse issued by the recording device 14 needs to be after the exposure of the film camera 11 is completed, but since the recording operation of the recording device 14 normally takes 16 msec to several tens of msec, the recording operation of the recording device 14 itself is After the end, there will be no problem if pulse output is made to the display unit 15.

No pulse is output to the display during reproduction of the recorded image immediately after recording. Therefore, during that time, the numbers on the display 15 remain as they were at the time of recording, and what is displayed on the monitor 18 is the reproduction of the recorded image.Therefore, the identification numbers displayed here are those at the time of recording. Match.

A pulse is output to the display unit 15 when switching from recorded image reproduction to through. Then, the display unit 15 counts up, and since the number displayed on the monitor 18 together with the through image is for the next recording, this also counts up, and they coincide with each other.

The second embodiment will be described with reference to FIG.

In this embodiment, the recording device 14 and the display 15 of FIG. 1 are provided with communication means, and the recording device 24 provided with the communication circuit and the display 25 provided with the communication circuit shown in FIG. Connected by. This allows the recorder 24 to display
Since not only the identification number but also the symbol data can be sent to 25,
The customer's name, etc. can also be displayed, further facilitating verification.

As a communication method, digital data can be transmitted by RS232C, LAN or the like.

A third embodiment will be described with reference to FIG.

This embodiment is a further development of the second embodiment and uses the recording machine 24 of FIG. 2 based on a personal computer. The recorder 34 of FIG. 3 is provided with a video capture board for inputting a signal from the light receiver 16 and a video signal from the video camera 13 to a personal computer, and after temporarily capturing an image here, the image compression board compresses the image. After recording, record on the recording medium. If the image compression may take a long time, the compression board may be omitted and the compression processing may be performed by software. Also,
If the recording medium has a large capacity, it may be possible to record without compression. A floppy disk or a magneto-optical disk is used as the recording medium. In the case of a floppy disk, compression is necessary because the capacity is small.

When handling a large number of customer photographs in a photo studio, customer data may be handled by a personal computer. In this case, if a synchronized shooting system based on a personal computer is used, the customer data management personal computer 37 is connected via the net, customer data is input from the customer data management personal computer 37, and the customer's name or registration number is entered. Can be recorded on both the film image and the electronic image by the recorder 34.

A fourth embodiment will be described with reference to FIG.

The film camera 41, the strobe 42, the video camera 43, the display 45, the light receiver 46, and the monitor in this embodiment.
Reference numerals 48 are the same as those shown in FIG. 1 of the first embodiment, respectively. However, the recorder 44 is different from the first embodiment in that it does not have a function of outputting a count-up pulse. Therefore, the recorder 44 and the indicator 45 are not connected, and the receiver 46
And the indicator 45 are connected, and the signal of the light receiver 46 is branched and input to the indicator 45.

As described above, the flash 42 is used in this embodiment.
Since the light receiver 46 detects the light emission of the display 45, the display 45 operates. Therefore, in the case of a non-emission type display, it is sufficient that the number does not change until the flash emission ends (several hundred μsec). . Even if the number changes after that, since the strobe light emission has ended, that number hardly causes exposure. An example of this type of display is a structure in which a thin plate on which numbers are written is mechanically turned over.

In the case of a light emitting type display, a film camera 41
If the identification number on the display 45 changes while the shutter is open,
Both the numbers before and after the change may be exposed.
Therefore, an operation delay of several tens of msec or more is required for the number changing operation of the display unit 15, and it is desirable that the display unit 15 has a long time to change the identification number after receiving the pulse.

A fifth embodiment will be described with reference to FIG.

Like the fourth embodiment, the recorder 54 in this embodiment does not have the function of outputting a count-up pulse, and other film cameras 51, strobes 52, video cameras 53, displays 55, The light receiver 56 and the monitor 58 are also the fourth
It is similar to that shown in the embodiment. However, in this embodiment, since the indicator 55 whose identification number changes rapidly is used, the synchronizing circuit in the film camera 51 is connected to the indicator 55. Normally, at least several tens of msec or more, from 100 m in some cases until the flash fires after the sync circuit turns on.
Since it takes more than sec, the identification number of the display 55 may be changed during this period. Therefore, an inexpensive display device using an LED or the like can be used.

At the time of recording, the identification number counted up to the number displayed on the display 55 when recording the through image on the monitor 58 is recorded.
If the same identification number is displayed on the monitor on the side of the recorder 54, it is possible to avoid discomfort because the identification numbers match. Therefore, in this case, it is desirable that the recording machine 54 side also perform the count-up operation immediately before recording.

A sixth embodiment will be described with reference to FIG.

This embodiment does not use the display of the previous embodiment, but incorporates a recording device in the film camera 61 for generating an identification number and recording directly on the film. In addition, the recorder 64
Has a counter for counting the same identification number as in the previous embodiment. Others are the same as in the previous embodiment. When the subject 60 is photographed by the film camera 61, the strobe 62 emits light and the identification number is recorded on the film. Also,
The video camera 63 is also shooting before the film camera 61 shoots. The receiver 66 that detected the strobe light is a recorder
When a signal is sent to 64, the recorder 64 records only one frame of an image by the video signal from the video camera 63, and records the same identification number as the film camera 61 from the counter.
The identification number of the recorder 64 is set to the same number as the identification number of the film camera 61 in advance before shooting. Therefore,
The identification number recording device of the film camera 61 and the counter of the recording device 64 may perform an operation of counting up 1 or a fixed number each time a picture is taken.

As described above, since the display device is not required in this embodiment, the wiring for the display device is troublesome, and the display device is surely imaged on the periphery of the screen together with the subject during photographing.
It frees you from the hassle of having to set a film camera and a video camera.

FIG. 7 is a schematic diagram of recording the identification number from the base side of the film in the film camera 61. The film F is pulled out from the cartridge P and the shooting lens L
Is exposed by, and then wound on the reel R. On the base side of the film, there is arranged a recording means 71 for recording an identification number by a light emitting element such as an LED or irradiating an LCD for recording and counting up after recording one frame.

FIG. 8 is a schematic diagram of recording the identification number from the emulsion side of the film in the film camera 61, which is suitable when a film having a light-shielding backing paper such as a Brownie film is used. A light emitting element 73 and a small lens 74 are arranged outside the optical path in the vicinity of the taking lens L, and the identification number formed on the light emitting element 73 is irradiated onto the corner Fa of the film F and recorded.

Similar to FIG. 8, FIG. 9 is for recording from the emulsion side of the film, but the recording portion Fb for recording by the light emitting element 75 and the small lens 76 is provided outside the screen on the reel R side. There is. In this camera, the film is automatically wound immediately after being photographed, one frame is fed, and then recorded in the recording unit Fb. In addition, at the position in the screen corresponding to the recording portion Fb, the light shield plate 77
If the object light is not exposed, the recording section Fb records only the identification number so that it can be clearly recognized.

FIG. 10 is a view of an LED array, which has a light emitting portion of a plurality of dots and is arranged at right angles to the film running direction,
While the film is running, each light emitting part blinks to form a number or symbol. Since this LED array requires a smaller recording unit than that in FIG. 8, the camera can be downsized. It should be noted that an LCD may be used instead of the LED, and irradiation may be performed from the back surface.
