It is supplied to the camera-side video circuit 12 via the imaging circuit 13.

The video signal output from the camera-side video circuit 12 is
The signal is applied to a magnetic head 19 slidably in contact with the recording medium 3 via a recording / reproducing unit 17 and a head amplifier 18 to be magnetically recorded, and a signal read by the head 19 is transferred to the camera via a path reverse to the above. It is supplied to the side video circuit 12. The camera-side circuits are supplied with power from a camera-side DC-DC converter 14. The camera-side main power supply 16 or the monitor-side power supply 24 is supplied to the converter 14 by a power supply switching circuit 15.
To switch and input.

The operation of the present embodiment configured as described above will be described with reference to the flowcharts of FIGS.

FIG. 5 is a flowchart of the reproducing operation. In the figure, the electronic camera 1 with the recording medium 3 inserted in step S1
Is attached to the TV receiver 2, that is, the monitor, together with the main body.
In this case, after attaching the electronic camera 1 to the TV receiver 2,
The recording medium 3 may be inserted. When the electronic camera 1 is attached to the TV receiver 2 in this way, the process proceeds to step S2,
"Put remote control function on camera side by detecting camera insertion". Therefore, the remote control transmitter 4 (see FIG. 1) is operated to transmit a remote control signal to the remote control light receiving section 1b of the electronic camera 1, thereby performing a remote control operation. Then, step
Proceeding to S3, the monitor-side system controller 21 and the camera-side system controller 11 are connected, and communication with each other is started.

In step S4, a TV channel key or a remote control key is operated to set a reproduction mode. When the playback mode is set by operating this remote control key, a playback key may be provided in the remote control transmitter 4 or a number such as 1-2 or 3-3 is transmitted and decoded by the camera. To set the playback mode. Then, proceeding to step S5, when the electronic camera 1 is set to the reproduction mode, the signal read from the recording medium 3 by the magnetic head 19 is transmitted to the camera side video circuit 12 via the amplifier 18 and the recording / reproducing unit 17. Is supplied to the CRT 23 via the monitor-side video circuit 22, and is displayed on the monitor (step S).
6). The above is the description of the reproducing operation.

Next, the recording operation will be described. This recording operation includes (1) when recording image information captured by an electronic camera (2) when recording a signal from an external input device such as a VTR or the like on a TV receiver (3) input from a TV tuner There are three cases in which the recorded signal is recorded.

FIG. 6 is a flowchart for recording image information captured by the electronic camera 1 mounted on the TV receiver. In this case, the taking lenses 1c and 1Ac of the electronic camera 1 (FIGS. 1 and 3)
) Are directed towards the operator of the camera. Therefore, when the camera operator wants to take a picture while checking his / her own form, it is necessary to display the monitor on the CRTs 2c and 2Ac. Then, with the remote control transmitter 4 held at hand, the user takes a picture while confirming his / her own remote control key at the best expression.

In FIG. 6, in steps S 11, S 12, and S 13, the electronic camera inserted with the magnetic disk is mounted on the monitor, and the remote control function is given priority on the camera side. The system controllers are connected to each other and communication is started. Proceeding to step S14, the remote control key or the TV channel key is operated to set a mode for recording the captured image information, and then proceeding to step S15. In step S15, image information captured by the electronic camera is displayed on the CRT 23 via the camera-side imaging circuit 13, the camera-side imaging circuit 12, and the monitor-side imaging circuit 22. As a result, before recording the image information captured by the electronic camera 1, the image information can be displayed on a CRT and searched for a photo opportunity.

Then, the process proceeds to step S 16, where recording is performed by operating the remote control key or the TV channel key at the time of the best photo opportunity, that is, the signal of the camera side video circuit 12 is recorded / reproduced by the recording / reproducing unit 17 and the amplifier 18 via the magnetic head. 19 to be written on the recording medium 3.

FIG. 7 is a flowchart of a mode for recording an external signal input from an externally connected device such as a VTR. In the figure, steps S21 to S23 correspond to step S1 described above.
The description is omitted because it is the same as 1 to S13. Step S24
When the operation proceeds to step 4, the remote control key, the TV channel key, or the input switch 27 on the monitor side is operated to input the external input 28 (FIG. 4).
Set the recording mode. Then, the external input 28 is input switch 27, monitor system controller 2
1. The information is displayed on the CRT 23 via the monitor-side video circuit 22 so that the external input 28 can be confirmed before recording. Next, proceeding to step S26, the external input 28 is recorded by operating the remote control key or the TV channel key.

That is, the signal of the monitor side video circuit 22 is transferred to the camera side video circuit.
The data is supplied to the magnetic head 19 via the recording / reproducing unit 17 and the amplifier 18 and written on the recording medium 3. In this case, as a matter of course, communication between the camera-side system controller 11 and the monitor-side system controller 21 is always performed.

FIG. 8 is a flowchart of a mode for recording a signal from the TV tuner. In this mode, the input switch 27
By switching (see FIG. 4) from the external input 28 to the TV tuner 26, the recording operation can be performed in almost the same flow as in FIG. 7 described above, and a description thereof will be omitted.
