ABSTRACT:
In an electronic still camera which digitizes a video signal to store it in a memory and displays the signal by reproducing means, a multi-picture control circuit and method for an electronic still camera are disclosed. The circuit comprises a picture selector for inputting a picture to be displayed or a detecting completion instruction, a microcomputer for inputting an instruction from the picture selector to perform a predetermined control, and a multi-picture controller for generating a read address of one picture or multiple pictures written in a main memory under the control of the microcomputer. The circuit and method are capable of displaying more than one picture onto the picture display at a time, thereby reducing the time required to detect more than one picture's worth of data written in the main memory of an electronic still camera.
