ABSTRACT:
A CCD image sensor includes a plurality of uniformly spaced photodiodes arranged in series in vertical and horizontal directions, a horizontal signal transferring region formed integrally in a zigzag from between adjacent sets of said plurality of horizontally arranged photodiodes, a signal flowing direction changing region formed under the last set of the plurality of horizontally arranged photodiodes and at output of the horizontal signal transferring region, a signal processing region for storing temporarily signal charges from the horizontal signal transferring region or the signal charges from the signal flowing direction changing region and then resetting the signal charges, and a sensing amplifier for sensing states of the signal charges being temporarily stored in the signal processing region and amplifying the sensed states of the signal charges by a predetermined amplification degree, whereby the CCD image sensor is capable of being driven by a small number of clock signals so that it can be applied to a system requiring a lower resolution.
