<p>In a solid-state image pickup apparatus including a pixel array having pixels each including photoelectric conversion element arranged in a matrix, a synchronization signal generation unit generates a horizontal synchronization signal to define a first horizontal period and a second horizontal period different in length from the first horizontal period. Based on the horizontal synchronization signal, a reset scanning circuit sequentially selects and resets pixels in rows of the pixel array, and a readout scanning circuit sequentially selects pixels and reads a pixel signal therefrom. In each pixel, the charge is accumulated in a charge accumulation period starting when the resetting is performed and ending when the pixel signal is read. In one vertical period, the first horizontal period and the plurality of second horizontal period both appear a plurality of times, wherein the second horizontal period appears periodically.</p> |
