Abstract
Abstract An electronic still camera is provided, which can maintain a photographing order (recording order) of frames by only partially updating information even when an arbitrary frame recorded in a memory is erased, and new data is re-recorded in the corresponding area. The camera may include a designation unit for designating arbitrary image data in a memory in which a plurality of image data and administration data for administering the image data are recorded, and an erase unit for erasing administration data corresponding to designated image data designated by the designation unit. Furthermore, the camera includes an updating unit for updating administration data corresponding to image data obtained by an image pickup operation immediately before the designated image data is obtained, or administration data corresponding to image data obtained immediately after the designated image data is obtained, in correspondence with an erase operation of the erase unit.
