1. An optical sensor device, comprising:
a first light receiving unit in which a first light receiving element of a first type and a second light receiving element of a second type are integrated in a vertical structure; a second light receiving unit in which a third light receiving element of the first type and a fourth light receiving element of the second type are integrated in the same vertical structure; and a switch unit configured to switch between a first phase, a second phase, and a third phase between the first phase and the second phase in a time-division manner, the switch unit selecting in the first phase the first light receiving element from the first light receiving unit as a first detection signal and the fourth light receiving element from the second light receiving unit as a second detection signal simultaneously, selecting in the second phase the second light receiving element from the first light receiving unit as the second detection signal and the third light receiving element from the second light receiving unit as the first detection signal simultaneously, and blocking in the third phase an output of the first light receiving unit and an output of the second light receiving unit. |
