FIGS. 1 and 2 are examples of an Sv camera in which a wireless remote control function and a film shooting function are added. Here, the film photographing function is for photographing and recording negative or positive film photographed by a general silver halide camera using the S2 left camera body.

In FIG. 1, 1 is a camera body, and 2 is a power supply cover, which is shown attached to the camera body 1. 3 is a film adapter, 4 inside is a film, 5 is an illumination light source, 6.
14, 15, and 16 are each switch.

7 is an interface adapter to which cables 8 to 10 are connected. A cable 8 connects the film adapter 3 and the interface adapter 7, and includes a line connected to a switch of the film adapter 3, a power line, and the like. 9 is a cable connecting the power supply coupler 1 and the interface adapter 7;

A light receiving window provided in the receiver receives an infrared light signal from a wireless remote controller (not shown).

When photographing with film, first connect the camera body 1 to the film adapter 3 as shown in FIG. Then, the film 4 is set and the illumination light source 5 is turned on. As a result, the image on the film 4 passes through a normal photographic lens optical system (not shown) of the camera body, and is converted into an image signal by an image sensor (not shown). Here, lighting is turned on by turning on the switch 6 provided on the film adapter 3, and recording is performed by turning on the recording switch 14.

Next, an example of the circuit configuration of the camera body 1, interface adapter 7, film adapter 3, and power coupler 2 will be described in detail with reference to FIG.

In Figure 2, block 1 surrounded by a dotted line is the camera body, block 2 also surrounded by a dotted line is the camera head, block 3 also surrounded by a dotted line is the film adapter, and the same (block 7 surrounded by a dotted line is the interface). Adapter.

A signal line cable 8 from the film adapter 3 is connected to the interface adapter 7 via a connector 11.
It is directly connected to the cable 9 to the camera body 1 side. Also, from the video output terminal, the Y+S signal and chroma signal from the cable 9 to the camera body l are mixed into the mixing circuit 701.
The signals are added together and output as a video signal.

In the power coupler 2, 21 is a sensor that receives infrared light from an infrared wireless remote control, 22 is a one-chip microcomputer and has a serial data communication port, and this port can switch between a communication port and a normal output port. (For example, NECμPD7
564 etc.). 23 is a regulator that supplies power for the microcomputer. This regulator is controlled by a control signal/CPU0N28 from the camera body 1. When CPU0N becomes Low, the regulator becomes ENABLE and the microcomputer 22 operates. The microcomputer 22 has switches 14.15.1 for the film adapter 3.
6.36 signals are connected, and the microcomputer 22 can detect the states of these switches. 24 is a light receiving sensor output, which is detected by the microcomputer 22 and identifies the code of the remote control. 25 to 27 are serial communication lines between the camera body 1 and the microcomputer 22 in the power coupler 2, 25 is a serial communication data line, 26 is a serial communication taro line, and 27 is a serial communication BUSY line.

Next, in the camera body l, 101 is a microcomputer that controls the camera body, and is a microcomputer (for example, Mitsubishi M37410) that has a standby mode that operates with low power consumption and an operation mode that consumes more power but operates at high speed.

102 is a serial-parallel converter for converting serial communication data from the microcomputer 22 in the power supply coupler into parallel data and communicating data with the microcomputer 101 in the camera body 1. Here, the data line 25 is connected to the microcomputer 101.

Reference numeral 106 is an image capturing, recording and reproducing processing system block of the S camera. .

A video signal reproduced from a video floppy (not shown) or a video signal from an image sensor shell is output as a Y+S signal and a C (chroma) signal. 107 is a character generator, which is an IC for displaying characters, etc. on a TV monitor (not shown).
It is.

The microcomputer 101 of the camera body l receives the control signal 28
By keeping /CPU ON Low, the regulator 23 in the power coupler 2 becomes ENABLE, and the microcomputer 22 operates. In this state, the microcomputer 22 in the power supply coupler detects the state of the film adapter switch and serially transfers code data based on this to the serial/parallel converter 102 in the camera body.

A microcomputer 101 in the camera body takes in data in a serial-parallel converter 102 and controls the camera body based on this data.

These steps are shown in a flowchart as shown in FIG.

The operation will be explained below.

First, it is checked by Sl whether new data is prepared in the serial/parallel converter 102 (Ready?).

If it is Ready, data is fetched in S2.

In S3, check the data obtained in S2 and switch BLON3.
Check if 6 is on. If it is ON, check whether switch N/P16 is negative or positive in S4. S for NEGA
Step 5 sets the camera's recording mode to NEGA/PO3I inversion mode (NEGA mode). If it is PO3I, the recording mode of the camera is set to NEGA/PO3I non-inversion mode (PO3I mode) in S6.

Next, in 87, the Rec switch 14 is turned on, and in S8, the Rec switch 14 is turned on.
If the c flag is not set, film photography is performed in S9, the Rec flag is set (SIO), and the process returns to L■.

If the Rec flag is set in S8, it means that film photography has already been carried out, and the camera body is put into the reproduction mode by turning on the power of the reproduction system in order to reproduce the photographed image in Sll.

Next, at 812, the ERASE switch 15 is ON and the ER
If the ASE flag is not set, the image being played back is erased in S14. Then, in order to remember that the data was erased in S15, an Erase flag is set, and the process returns to (2).

When the ERASE switch 15 is OFF in S12 or S
If the ERASE flag is set in step 13, there is no need to erase, so return to step 13. Rec switch 14 on S7
is OFF, the Rec flag is set in S16 and S17, and if the Erase flag is not set, the recording head is moved to the next track position in 818, and the process proceeds to (2).

If the Rec flag is cleared and the Erase flag is set in S16 and S17, it is possible to record on the current track, so proceed directly to (2). ■In S19, Rec flag,
Clear the 520TErase flag and return.

If the serial-parallel exchange is not data ready in Sl or if the BLON switch 36 is OFF in S3, the process advances to S20.

In S20, if the recording trigger switch 108 of the camera body is ON, a normal photographing sequence (S21) is performed and the process moves to (2).

If the switch 108 is OFF, the process directly moves to (2).

Here, since the normal photographing sequence is a sequence for recording a general subject, not a film, a detailed explanation will be omitted here.

Furthermore, since the playback mode in Sll also refers to the playback operation of a normal still video camera, a description thereof will be omitted.

With the above flow, in film mode, press the Rec switch 1.
Record a film image by turning on 4, play it back by holding the Rec switch (ON), check the recorded image, and if you think it is unnecessary, press ERASE switch 15.
It is erased by turning on.

In addition, when erasing, the recording head is not moved to the next track, so an instantaneous image is recorded at the original track position.

[Other Examples]

In the embodiment described above, the illumination switch of the film adapter and the film photographing mode switch are linked together, but they may be linked by a relay or the like.

For example, the 0N10FF of the film photography mode switch may be connected so that it can be detected by a microcomputer as in FIG. 2, and the output of this film photography mode switch may be connected to a relay, which then turns the illumination to 0N10FF.

Further, in the embodiment described above, the illumination of the film adapter is turned on by a switch, but the present invention is also effective even if the illumination is turned on by connecting the cable 8 to the interface adapter 7. That is,
Since it is the same as keeping the switches 6 and 36 always ON, that is, normally, in FIG. 2, it is sufficient to omit the switch portion 6.36 and short-circuit that portion. By doing so, the microcomputer 22 can detect the connection of the cable 8 and the lighting of the light.

Further, in this embodiment, the DATA line is used as a signal for changing the microcomputer of the camera body from the standby state to the operating mode, but this may also be a CLK line necessary for communication.

Alternatively, communication may be made not only in one direction but also in both directions from the microcomputer on the power coupler side to the main body side.

Alternatively, although the communication method is clock synchronous in this embodiment, it may be asynchronous.

Further, in this embodiment, a serial-parallel converter is provided in the camera body, but the microcomputer in the camera body and the microcomputer in the power coupler may communicate directly in serial.

Further, in the embodiment described above, a switch for erasing is provided independently, but this may be used also as a switch for other purposes.

For example, it may be a BLON switch that turns the lighting on and off.

In this case, it can be realized by recording with the Rec button, leaving it as it is, and erasing by turning off the light switch while in the playback state.

〔Effect of the invention〕

As explained above, since the recording mode immediately enters the playback mode, the recorded image can be quickly checked, and if it is determined that it is unnecessary on the spot, it can be erased with a single switch operation. And since it becomes possible to record immediately again, operability is greatly improved when you want to re-take pictures over and over again.

Furthermore, since erasing is possible only immediately after recording, it is possible to prevent other images from being erased by mistake.
