Color linear image sensor device with shutter function for charges in photodetectors and method of manufacturing the same

摘要

A color linear image sensor device has a shutter function for selectively draining charges stored in a photodetector circuit. The color linear image sensor device includes first, second, and third linear image sensors having different sensitivities with respect to incident light and arranged successively in sensitivity decreasing order from the outermost, and a shutter gate and a shutter drain for adjusting an amount of exposure to the linear image sensor which has the highest sensitivity to incident light.
