Abstract
A digital camera includes a mode set switch. If a camera mode is set by mode set switch, the image data corresponding to a subject image taken by a CCD imager is processed by DMA, and outputted through a first bus onto a monitor. If a shutter button is operated, the first bus is connected to a second bus by a bus bridge and the image data is transferred from a first bus side to a second bus side. On the second bus side, the CPU processes the image data according to a program and records it on a memory card.
