ABSTRACT:
A semiconductor photosensor device includes a plurality of photodiode sections, a switch, and an output section is provided. The plurality of photodiode sections have different illuminance-output characteristics. The switch selects any one of the plurality of photodiodes sections on the basis of an illuminance of incident light irradiated on the photodiode sections. The output section outputs an signal from the selected photodiode section through the switch.
