The present invention is directed to a color linear sensor of a simple structure which can accurately measure a degree of a color mixture in a sensor section. In a color linear sensor having a dot-sequential sensor array (1), only one pixel of a predetermined color (R) in a reference pixel region (3) is allowed to receive an incident light. Then, a degree of color mixture is estimated by calculating a level difference between a signal output of this pixel and a signal output of a pixel of the same color as that of the former pixel in an effective pixel region (2). Also, the present invention is to provide a color linear sensor which can prevent sensors from being displaced from each other in position, simplify a configuration of an external circuit and which can prevent a color mixture from being caused by signal charges deteriorated after they are transferred by a transfer register. In a color linear sensor having a dot-sequential sensor array (1), read-out gates (22, 24) are formed as two-stage configuration for sequentially reading out signal charges from respective sensors (1R), (1G), (1B) of the dot-sequential sensor array (1) to a CCD register (23) at the unit of pixels, thereby to sequentially output signal charges of one line at every color in a line-sequential fashion.
