Abstract:
1. A control method for a solid-state imaging element including a photodetecting region having M×N (M is an integer not less than 3, N is an integer not less than 2) pixels each including a photodiode and a readout switch connected at one end to the photodiode that are arrayed two-dimensionally in M rows and N columns, and readout wiring lines arranged for each column, and connected to the other ends of the readout switches included in the pixels of corresponding columns, of selectively reading out, in each of the L times (L is an integer not less than 2) of imaging frames, charges accumulated in the pixels contained in one or a plurality of rows (hereinafter, referred to as readout object rows) that form a partial region of the photodetecting region, and in each of the L times of imaging frames, performing a removing processing of charges accumulated in the pixels contained in a part of the two or more other rows (hereinafter, referred to as non-readout object rows) than the readout object rows so that all of the two or more non-readout object rows are not reset, but only the part thereof is reset, as well as performing the removing processing at least once in a period of the L times of imaging frames for each of the two or more non-readout object rows.
