Abstract:
A solid-state imaging device includes: a pixel array section including an array of pixels in a two-dimensional matrix, the pixels including a photoelectric conversion section configured to generate signal charges in accordance with an amount of light, a discharge section configured to receive an overflow of signal charges exceeding a saturation amount of charges during an exposure period, at least a first charge accumulation section configured to receive the signal charges generated by the photoelectric conversion section after the exposure period, and a second charge accumulation section configured to receive the signal charges exceeding the saturation amount of charges, and a plurality of pixel transistors reading the signal charges; and a scanning section configured to scan the pixels so that accumulation periods for all the pixels are simultaneous in an accumulation period of the signal charges, and to selectively scan the pixels in sequence.
