Abstract
In an electronic still camera, image data obtained by a camera image pickup section are transmitted to an image data compression/extension circuit and are coded by this circuit. The coded image data are recorded to a FIFO circuit. The image data are then DMA-transferred to a memory card by a DMA controller within a memory card interface (I/F) and are recorded to the memory card. When the image data are regenerated, the image data are DMA-transferred in a reverse direction. In another camera, image data are outputted from a charge coupled device (CCD) and are converted to a digital signal. Sound data are outputted from a microphone and are converted to a digital signal. File header information is constructed by the image and sound data and is stored to a RAM of a memory card interface in advance. The file header information is recorded to a memory card by a direct memory access (DMA) control section. In another camera, a central processing unit (CPU) selects an image or sound format recorded to a recording medium. When these formats are used in various kinds of application programs in an information equipment, data are recorded to the recording medium in accordance with these formats.
