Abstract:
1. A solid-state image pickup apparatus comprising: a pixel array in which pixels each including photoelectric conversion element for converting light into a charge are disposed in a matrix; a synchronization signal generation unit configured to generate a horizontal synchronization signal including a plurality of pulses and having an interval of the pulses corresponding to a first horizontal period and an interval of the pulses corresponding to a second horizontal period different in length from the first horizontal period; a reset scanning circuit configured to, based on the horizontal synchronization signal, sequentially select pixels in rows of the pixel array and reset a charge accumulated in the photoelectric conversion element; and a readout scanning circuit configured to, based on the horizontal synchronization signal, read pixels in a row, to be read, of the pixel array, wherein in each pixel, the charge is accumulated in a charge accumulation period starting when the resetting is performed by the reset scanning circuit and ending when the pixel signal is read by the readout scanning circuit, and wherein a plurality of first horizontal periods and a plurality of second horizontal periods appear in one vertical period defined by an interval of a vertical synchronization signal.
