ABSTRACT:
A color linear image sensor includes a sensor pixel linear array with a plural number of color filters laid and bonded thereover, a readout circuit and an output processing circuit. The sensor pixel linear array consists of repeat patterns of color pixels linearly arrayed in a preset color order, the repeat patterns being symmetrical with respect to the midpoint of the sensor pixel linear array. The readout circuit reads out image signals line by line from the sensor pixel linear array. The output processing circuit distributes the readout signals into a plural number of color image signal routes, and outputs the readout signals of separated colors. The color linear image sensor thus constructed may be incorporated into an image processing system. The midpoint of the sensor pixel linear array is coincident with the optical axis of a lens of the optical system of the image processing system.
