ABSTRACT:
The object of the present invention is to reduce the line distance between light receiving elements for three colors of RGB of a color linear image sensor to reduce the required storage capacity for an external memory. The color linear image sensor is constructed such that a charge transfer element is disposed between each two adjacent light receiving elements of three rows and a charge read-out element is disposed between each charge transfer element and each of the light receiving elements on the opposite sides of the charge transfer element such that, when signal charges from the light receiving elements for different colors are to be transferred, each of the character transfer elements is used commonly and time divisionally by the centrally located light receiving elements and the light receiving elements on each of the opposite sides of the centrally located light receiving elements.
