ABSTRACT:
A photoelectric converter has photodetectors having plural arrays wherein plural photoreceiving elements are arranged for detecting incident light. The converter has a reading circuit for reading an output signal from the photodetector, the reading circuit having a detection circuit for detecting maximum and minimum signals from the plural photoreceiving elements of the photodetector. The photoelectric converter has at least three arrays arranged parallel to each other or substantially parallel to each other, and at least one array is arranged in a direction perpendicular to the at least three arrays. The reading circuit is arranged adjacent to the plural arrays, and the photodetectors and the reading circuit are provided on a common substrate.
