Abstract

PURPOSE:To facilitate an arbitrary data writing in a picture by recording information different from a subject on the magnetic disk of a magnetic floppy disk device. CONSTITUTION:A data picture with respect to a subject is decided, and an operation is shifted to a data input mode through the key operation of a data input device 25 or data photographing button 13. Then its data picture signal and a subject picture signal are taken out from the input device 25 side and a memory circuit 17, respectively, and synthesized by a signal synthesizer 19, after which it is recorded on a magnetic disk 29. When the recorded subject image and data picture signal operate a data read member 13, a switch 31 is switched to the side of a read circuit 21. Then said image and data picture signal are projected on a monitor television 26 and printed out.

It consists of a floppy disk drive circuit, etc. In the electronic still camera 1 of this embodiment, the jack 34 of the data input device 25 and the jack 34 of the monitor 26 can be connected via the interface 18.

In this system, when photographing with the electronic still camera 1, the camera 1 directed toward the subject 28 has an I! Object light enters through the shadow lens 414 2, and this object light is split by the mirror 10 into a light beam directed toward the finder (not shown) via the pentaprism section 8 and a light beam directed toward the solid-state R pixel element 9. be done. Further, the light beam directed toward the solid-state image sensor 9 is normally blocked by the shutter 1.1 disposed on the 11α surface of the fixed image sensor 9, so that it does not reach the surface of the fixed image sensor 9. However, once the composition in the viewfinder is decided and the operator presses the shutter button 12, the C
Under the control of the PU 16, the shutter 11 is opened for a certain period of time 1. During the opening of the shutter 11, an image of the subject 26 is formed on the surface of the solid R1 pen 9. Further, when the shutter button 12 is pressed, the floppy disk device 14 starts operating via the CPIJ 16 in conjunction with this operation, and the disk drive mechanism (not shown) rotates the two magnetic disks. Further, the magnetic head 30 for recording magnetic signals on the magnetic disk 29-1 is normally connected to the recording circuit 20 via the switch 31.Then, a subject image is formed on the solid-state image sensor 9. Then, the signal from the solid-state image sensor 9 is inputted to the recording circuit 20 via the cpuie, and further transferred to the magnetic disk 29 via the magnetic head 30.
On the top, one track of video signals is magnetically recorded. When the recording of one track's worth of image signals on the 11-track disk 29 is completed, the drive of the floppy disk device is stopped and the next footprint is made. In this way, a video signal of 1σ for each shot is recorded on the magnetic disk 29 by sequentially changing the tracks, and normal video recording is performed.
