Abstract: A photoelectric conversion apparatus comprising: pixels; L (L≥3) vertical signal lines disposed on each pixel column; M (M≥2) selection circuits disposed in each pixel, each of the selection circuits respectively connecting one of the pixels to a different vertical signal line; a vertical scanning circuit configured to scan the selection circuits; and a control unit. The control unit sets first operation mode in which the vertical scanning circuit performs a single read scanning operation at a time, and a second operation mode in which the vertical scanning circuit performs multiple read scanning operations at a time. In the first operation mode, the control unit uses first selection circuit out of the M selection circuits for scanning operation. In the second operation mode, the control unit uses a second selection circuit, which is different from the first selection circuit, out of the M selection circuits for scanning operation.

Abstract: A driving apparatus that outputs a drive signal for driving, per row, a plurality of pixels arranged to form a plurality of rows, the driving apparatus comprising a plurality of row driving units arranged to correspond to the respective rows, wherein each of the row driving units includes: a memory unit that holds a signal for controlling the pixels in a corresponding row to be set to a charge accumulation state or a reset state; and a selection unit that selects whether to cause a state of the signal held in the memory unit to transition when a signal for readout from the pixels is input.

Abstract: A signal processing apparatus includes an analog-to-digital conversion unit, a determination unit including a comparator, and a data calculation unit that performs calculation. The data calculation unit generates a first calculation result by performing calculation including processing for averaging a first digital signal and a second digital signal or processing for adding the first and second digital signals. The data calculation unit generates a second calculation result based on a difference between the first digital signal and first noise digital data. The data calculation unit switches whether to output the first calculation result or output the second calculation result, based on a comparison result of the comparator.
