ABSTRACT:
A display apparatus for an electronic image having an image memory for storing video image data of a number of fields or a number of frames, which are obtained by processing, with a signal processing circuit, a video image signal from an image detecting element on which reflected light from a subject is imaged through an optical system and displaying video image data stored in the image memory to form a picture having the desired field or frame on a display unit. The apparatus includes a timing generating circuit for generating a vertical synchronizing signal by which video image data derived from a video memory, in units of fields or frames, is displayed as video image data on the display section, and a control means, responsive to the vertical synchronizing signal from the timing generating circuit, for sequentially switching video image data derived from the video memory of the desired frame or field, to supply the video image data to the display unit.
