Abstract
Abstract A digital electronic still camera to which detachably connected is a semiconductor memory module (90) adapted for storage of video signals representing a still image in the form of digital data. The camera includes a connector (14) for detachably and electrically connecting the semiconductor memory module (90), an imaging subsystem (12) including an image pickup device (22, 28) and adapted for imaging a scene and producing video signals representative of the scene in a dot-sequential manner, a signal processor (40, 72, 56, 78, 36, 62, 68) for converting the video signals produced from the imaging device into component signals and developing the component signals in the form of digital signals, and a control unit (24, 30, 44) for controlling the imaging subsystem (12) and the signal processor (40, 72, 56, 78, 36, 62, 68) to cause the imaging subsystem (12) to shoot the scene, the control unit (24, 30, 44) causing the signal processor (40, 72, 56, 78, 36, 62, 68) to convert the resulting video signals into the component video signals. The control unit (24, 30, 44) supplies to the connector (14) control signals for writing the component signals into the semiconductor memory module (90).
