Abstract

PURPOSE:To allow simple editing by providing a switching means and a combining means which combines an electronic still camera and a regenerator on the electronic still camera side respectively. CONSTITUTION:When editing is executed, a switching means SW installed at the inside of an electronic still camera is switched on the opposite side of the side shown in the figure. Then, the track of a magnetic disk 20 is switched on a regenerator 2 side, and the still picture is projected on a monitor television set sequentially. When the desired still picture is projected, the luminance signal and the chrominance signal from the regenerator 2 are supplied to the camera 1 side through a combining means 21. A recording circuit 6 which receives them through the switching means SW converts them to recording signals and records them in a magnetic disk 10. Thus, simple editing can be executed by repeating the above-mentioned processing.

Electronic still camera systems have been developed that reproduce images on a playback device and display still images on a TV monitor.

However, in this electronic still camera system, it is difficult to erase all of the information recorded on the disc sheet from just one track, and in order to erase the information, it is necessary to erase all the information written on the disc sheet. Therefore, users are requesting to edit still images appropriately from a large number of still images recorded with electronic still cameras and to save edited disk notes.

This type of editing machine has many functions, but is expensive and is considerably larger and takes up more space than the above-mentioned general playback machine. Therefore, simple playback and editing are desired in such electronic still camera systems.

DISCLOSURE OF THE INVENTION The present invention provides an F435 still camera system that allows such editing to be performed with a simple IC L or low-cost device by using an electronic still camera and a number of endogenerated cameras. This is what we propose.

Therefore, in the present invention, the video input to the electronic still camera, which is used exclusively for recording, is converted into 18 images at once using an image pickup device such as an OCD, and all of the switches are switched to the part that is manually operated in the distribution circuit section. It is configured so that either the signal from the optical system or the image information signal output from the 11-stage sensor can be selected by cutting and pressing.

As a result, according to the present invention, it is possible to transfer and record the reproduced still image onto a disk sheet using the Kameko still camera 1, which is convenient because simple editing can be performed.
