    Abstract: A plurality of pixels are arranged two-dimensionally in a matrix and individually include a first photosensitive portion and a second photosensitive portion. A plurality of first wirings connect a plurality of first photosensitive portions to each other for every row. A plurality of second wirings connect a plurality of second photosensitive portions to each other for every column. A first reading unit is arranged to read signal data through at least some of the plurality of first wirings. A second reading unit is arranged to read signal data through at least some of the plurality of second wirings. The first reading unit has a reading pixel setting unit arranged to set, based on signal data read in the first frame, a pixel group for reading signal data in a second frame subsequent to a first frame from the plurality of pixels.

    Abstract: Provided is a position detection sensor. In a first pixel part, as an incident position is closer to a first end of a first pixel pair group in a second direction, an intensity of a first electric signal decreases. In a second pixel part, as the incident position is closer to the first end, an intensity of a second electric signal increases. In a third pixel part, as the incident position is closer to a second end of a second pixel pair group in a first direction, an intensity of a third electric signal decreases. In a fourth pixel part, as the incident position is closer to the second end, an intensity of a fourth electric signal increases. A calculation unit calculates a second position on the basis of the first and second electric signals, and calculates a first position on the basis of the third and fourth electric signals.

    Abstract: In a first pixel part, as an incident position is closer to a first end of a first pixel pair group in a second direction, an intensity of a first electric signal decreases. In a second pixel part, as the incident position is closer to the first end, an intensity of a second electric signal increases. In a third pixel part, as the incident position is closer to a second end of a second pixel pair group in a first direction, an intensity of a third electric signal decreases. In a fourth pixel part, as the incident position is closer to the second end, an intensity of a fourth electric signal increases. A calculation unit performs weighting on a first position on the basis of the third and fourth electric signals, and performs weighting on a second position on the basis of the first and second electric signals.
