Next, the operation of the above configuration will be described. First, a case where a still image is recorded on the magnetic disk 6 will be described.

The CPU 10 includes an image sensor driving circuit 3
To output a drive command signal. Thereby, the image sensor driving circuit 3 causes the image sensor 2 to perform a scanning operation. The image sensor 2 converts an image incident from the lens 1 into an electric signal, and outputs the electric signal to the imaging signal processing circuit 4. The imaging signal processing circuit 4 converts the input electric signal into, for example, an NTSC video signal. At this time,
When the operator looks into a finder (not shown), the video signal processed by the imaging signal processing circuit 4 can be displayed and monitored on a liquid crystal display, for example.

The user operates the shutter of the operation switch 13 at a desired timing while looking through the finder. By this shutter operation, the CPU 10 sends an output command signal to the imaging signal processing circuit 4. In addition, the CPU 10
Sends a drive command signal to the magnetic disk drive circuit 8 at substantially the same timing as the shutter operation. Upon receiving the drive command signal, the magnetic disk drive circuit 8 rotates the motor 7 to control the rotation of the magnetic disk 6 at a predetermined rotation speed.

On the other hand, the imaging signal processing circuit 4 which has received the output command signal converts the video signal (still image signal) into a recording / reproducing circuit 5.
Send to The recording / reproducing circuit 5 converts this video signal into, for example, FM
The data is modulated and recorded on the rotating magnetic disk 6 via the magnetic head 9.

Next, a case where a video signal is read from the magnetic disk 6 will be described.

First, as shown in FIG. 2, it is assumed that the still video apparatus main body 21 is connected to the TV monitor 15 via a transmission line 22.

The operator operates the reproduction switch of the operation switch 13. At this time, the CPU 10 sends a drive command signal to the magnetic disk drive circuit 8. The magnetic disk drive circuit 8 that has received the drive command signal controls the rotation of the motor 7 so that the magnetic disk 6 rotates at a predetermined rotation speed.
The magnetic head 9 reads a signal from the rotating magnetic disk 6 and sends the signal to the recording / reproducing circuit 5. The recording / reproducing circuit 5 demodulates the received signal FM, and
Send to 4. The screen display circuit 14 sends a video signal to the TV monitor 15 to display the video signal.

Thus, the video signal is reproduced from the magnetic disk 6 and displayed on the monitor.

Next, a method of setting the functions of the still video device and the operation mode thereof will be described. 3 and 4
5 is a flowchart showing a method for setting a function and its operation mode. FIG. 5 shows a display screen (menu screen) at the time of setting a function and its operation mode.

The functions mentioned here indicate, for example, the zoom speed when the operator operates the zoom switch of the operation switch 13, and the display time of each of a plurality of still images continuously reproduced from the magnetic disk 6. Or a track number indicating the number of a track on the magnetic disk 6 on which a still image is recorded.

When the operator operates the HELP key of the operation switch 13, it is determined that the HELP screen display switch is ON (step S1). At this time, the CPU 10
Sends the main menu screen data stored in the ROM 11 to the screen display circuit 14, and displays the main menu screen (various setting menu screen) 31 (see FIG. 5) on the TV monitor 15 (S2). When the HELP key is not operated, the main menu screen is not displayed (S1).

The value of the type N of the selected function is determined in steps S3 to S6, and any one of steps S7 to S10 is performed according to the determined value of N. Steps S7 to S10 display a screen corresponding to the value of N. For example, if it is determined that N = 1, a submenu screen (screen of an operation mode) corresponding to N = 1 is displayed in step S7. In this case, since N = 1 is the zoom speed setting, the zoom speed setting screen 32 is displayed. When N = 2, the interval setting screen 33 is displayed (see FIG. 5).

After the submenu is displayed, step S
Eleven input processes are performed. The subroutine of the input processing S11 is shown in FIG.

As shown in FIG. 4, the operator changes one of the functions displayed on the sub-menu screen to the UP mode.
Select with the / DOWN key, numeric keypad, etc. CPU10
Reads the input of the type P of the selected operation mode (S
21). When the sub-menu screen is at the zoom speed setting 32, for example, P = 1 is slow, P = 2 is slightly slow,...
.., P = 5 means end. When the submenu screen is the interval setting 33, for example, P = 1 is 5 seconds, P =
2 is 10 seconds,..., P = 5 is end, etc. (see FIG. 5).

After the input of the type P of the operation mode is read in step S21, the P is read in steps S22 to S24.
Is determined. In steps S25 to S27, a setting corresponding to the determined value of P is performed. This setting is
That is, the operation mode of the function is stored in the RAM 12.
If it is determined that P = 5 (maximum), the main menu screen is displayed again.
