Abstract
Electronic Imaging Apparatus is partitioned into separable modular units including an image pickup unit (4a) attachable to an image recording unit (2). The pickup unit (4a) is selected from a plurality of pickup units (4a, 4b), each producing image signals from an image sensor (6, 70, 71) uniquely devoted to the acquisition of a particular type of image (e.g., high resolution vs. low resolution, color vs. monochrome, NTSC motion vs. motion). By providing an identifying signal in connection with the pickup unit, the characteristics of the sensor (6) are specified to the recording unit. More specifically, the recording unit includes a buffer (36) for storing the image signals, a processor (40) for controlling the operation of the recording unit, including the buffer, and interface circuitry (10, 32) for responding to the identifying signal and enabling operation of the processor (40) according to the characteristics of the attached image pickup unit (4a).
