DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail below with reference to the drawings. FIG. 1 is a circuit block showing an embodiment of a multi-screen display system according to the present invention. In the figure, an imaging system is constituted by the lens 1, the diaphragm 2 and the CCD 3. The signal processing circuit 4 inserts a synchronizing signal or the like into the signal from the CCD 3 to create a predetermined video signal, performs emphasis processing, and then performs FM modulation. The recording circuit 5 adjusts the FM modulated wave (video signal) from the signal processing circuit 4 to an appropriate recording current, and then the head 14 records on an empty track. When the camera is activated, the CPU6
The electronic shutter circuit 9 is controlled so as to send out a timing pulse so that the shutter speed becomes a predetermined shutter speed. Also,
The aperture control signal is sent to control the aperture 2 so that the aperture value becomes appropriate, and the lens drive control signal is sent.
Focusing control of the lens 1 is performed.

The CPU 6 controls the servo circuit 10 together with the control of the image pickup system to drive the motor 11 to rotate the floppy disk 13 at a predetermined speed and phase. Further, the head drive circuit 12 drives the head 14 to seek to a predetermined empty track. The LCD 7 indicates various states of the electronic still camera, and performs, for example, mode display of multi-one-screen composite screen display. The key input unit 8 includes keys for shooting and reproducing operations of the electronic still camera, and further includes a multi-one-screen composite screen display key 8a for designating a multi-one-screen composite display mode. The CPU 6 controls the reproduction system circuit in addition to the control of the photographing system circuit as described above. When the reproducing circuit 15 receives a reproducing instruction, the reproducing circuit 15 reads the FM-modulated video signal from the seek track of the floppy disk 13, demodulates the FM-modulated wave, and then performs de-emphasis processing to restore the original video signal. .

The multi-screen system block receives a demodulation signal from the reproducing circuit 15 based on a control signal from the CPU 6 and creates a preset or designated number of multi-screens to reproduce the reproducing circuit 15. And a multi-screen memory circuit 18 for storing multi-screen data, an A / D converter 16 for A / D converting the demodulated signal of the reproduction circuit 15, image data of a designated track of one screen, and blue. A single-screen memory circuit 19 for storing the back image data, a multi-screen memory circuit 18, a memory circuit 17 having the single-screen memory circuit 19, and a D / A converter 20 for returning the read data of the memory circuit 17 to the original analog signal.
And the A / D converter 1 according to the control signal from the CPU 6.
6, a memory controller 21 for controlling the memory circuit 17 and the D / A converter 20.

Next, the multi-reproduction screen display operation of the circuit of FIG. 1 will be described with reference to the flow chart of FIG. When the main switch is turned on (step (hereinafter referred to as "S") 1), the CPU 6 determines whether the floppy disk 13 is loaded in the disk drive (S).
2). If the floppy disk 13 is not loaded, a warning to that effect is displayed on the LCD 7. When the mounting of the floppy disk 13 is confirmed, the head 14 is set to NO. 1
No. from the truck. It seeks up to 50 tracks and determines whether or not there is an image on each track (S3).

Then, the CPU 6 determines in S4 whether or not the operator has operated the multi-one-screen composite display key 8a of the key input unit 8. When the multi-one-screen composite display key 8a is not operated, the mode is changed to another mode (display of only one screen, display of only multi-screen, etc.). When the multi-one-screen composite display key 8a is operated, it is next determined whether or not there is an image on each track of the floppy disk 13 (S5). If there is no image on the track, warning processing is performed. If multi-one-screen composite display is possible, that is, if there is an image, the multi-screen is captured. The multi-screen capture is performed as follows. Since all the tracks are confirmed, the CPU 6 instructs the memory controller 21 to make two pages of 25 multi-screens. First, 25 divided memory spaces are created in the multi-screen memory circuit 18. The image data sequentially read from one track is reproduced by the reproducing circuit 15, converted into a digital signal by the A / D converter 16, and stored in the memory in order.

When the images of up to 25 tracks have been stored and the first page has been created, the second page is moved to and the similarly read image is stored in the multi-screen memory circuit 18. At first, since the image displayed on the single screen is not selected, the image data of the blue-back is written in the single screen memory circuit 19, and the CPU 6 causes the memory controller 21 to execute.
In response to this, an instruction is issued to read the blue-back image data of the one-screen memory circuit 19. Further, the memory controller 21 issues an instruction to the memory circuit 17 to arrange the multi-image data of the designated page of the previous multi-screen memory circuit 18 in an area designated in part of the blue back image data. Image data is sent from the memory circuit 17 to the D / A converter 20. The D / A converter 20 converts the analog signal, and an image in which a multi-screen is arranged on a part of the blue-back screen is displayed on a monitor (not shown) via the reproduction circuit 15.

The 25 multi-screen of the first page or the 25 multi-screen of the second page can be designated by the key operation of the key input unit 8. At this stage of display, the operator can specify one screen of the multi-one-screen composite screen display by using the one-screen selection key 8b of the key input unit 8 (S6). here,
