Abstract
An electronic still camera indicates the available capacity of a recording medium and the number of frames remaining that may be photographed, as well as warning by stages in at least two forms, based on the available capacity of the recording medium. The electronic still camera includes a photo lens, mirror, CCD, signal executing circuit, A/D converter, buffer memory, compression circuit, CPU, memory card, and indicator device. A CPU reads in the gross capacity and the written-on portion from a memory card and calculates the available capacity. When the available capacity becomes small, the indicator device that indicates the available capacity or the number of frames remaining that can be photographed begins to flash the display slowly on and off. When the available capacity grows even smaller and is almost gone, the display flashes rapidly on and off. In this way, the photographer can easily detect how many more frames he or she may photograph on the memory card.
