ABSTRACT:
A compact, energy efficient image sensor which enables transfer of images to an external system is made compact in size and low in power consumption comprises an image sensor control circuit20which operates to drive a CCD image sensor4and stores horizontal lines of image data in a line memory30.An HREF signal is raised in association with the storing operation. The external system monitors the HREF and supplies an external clock EXCLK to an image sensor2during an H level period according to its convenience. A memory control circuit34sequentially outputs image data from the line memory30to a data bus10in pixel units and in synchronization with the EXCLK.
