摘要： In a solid-state imaging apparatus, if the total read out time of all pixels is shortened when effective pixels are thinned out without thinning out OB pixels, then the rows have different reset time periods, and the problem of uneven charge accumulation time periods arises. An improvement by the present invention is that, if no signals are read out from a part of the rows in an effective pixel region to skip the rows, then the time period in which the rows to be skipped are selected is made shorter than that in which the rows from which signals are read out are selected, and the pixels in the optical black pixel region and those in the effective pixel region are driven by the drive pulses of patterns different from each other.

摘要： The present invention reduces differences in the influence of electric charge leakage from a non-read out region into multiple read out regions adjacent to a non-read out region. Reset scanning of that row in the non-read out region which adjoins the first or second read out region is started before read out scanning of the first and second read out regions.

摘要： A solid-state image pickup device includes an effective pixel portion in which effective pixels are arranged in a matrix, the effective pixels each including a photoelectric conversion unit and outputting a first signal, a non-effective pixel portion in which non-effective pixels are arranged in at least one row, the non-effective pixels each including no photoelectric conversion unit and outputting a second signal, a vertical scanning unit for selecting each row of pixels in the effective and non-effective pixel portions, and an input section for externally receiving a third signal used to change a driving mode of the solid-state image pickup device. The vertical scanning unit begins electronic shutter scanning upon pixels in the effective pixel portion and causes each of pixels in the non-effective pixel portion to output the second signal after the input section has received the third signal and before the first signal is output.

摘要： 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.
