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.

Abstract: Provided is a shape measurement sensor including a light-receiving unit and a calculation unit. The light-receiving unit includes a plurality of pixel pairs. Each of the pixel pairs includes a first pixel and a second pixel that is disposed side by side with the first pixel along a first direction. In the first pixel, as an incident position is closer to one end of the light-receiving unit in a second direction, an intensity of a first electric signals decreases. In the second pixel, as the incident position is closer to the one end, an intensity of a second electric signal increases. The calculation unit calculates the incident position in the second direction for each of the pixel pairs on the basis of the intensity of the first electric signal and the intensity of the acquired second electric signal.

Abstract: Provided is a position detection sensor including: a light-receiving unit that includes a first pixel, a second pixel and a calculation unit that performs center-of-gravity operation by using an intensity of first and second electric signals to calculate a first position. In the first pixel, as the incident position is closer to one end of the light-receiving unit in a second direction, the intensity of the first electric signal decreases. In the second pixel, as the incident position is closer to the one end, the intensity of the second electric signal increases. The calculation unit further calculates a second position on the basis of a first integrated value obtained by integrating the intensity of the first electric signal, and a second integrated value obtained by integrating the intensity of the second electric signal.
