There is described an electronic still camera for converting captured optical images into electric image signals. The electronic still camera includes a memory to store an image data set of a captured image and a photographing data set including a date-and-time of either capturing the image or storing the image data set; a detector to detect a residual storing capacity of the memory; and an eraser to remove an unnecessary image data set. When a plurality of image data sets are stored in the memory and the residual storing capacity of the memory decreases at a level lower than a predetermined value, the unnecessary image data set is selected, based on dates-and-times included in photographing data sets each of which corresponds to each of the plurality of image data sets, so that the eraser removes the unnecessary image data set from the memory.
