  • Publication number: 20100182469
    Abstract: The present invention relates to an image sensor capable of obtaining a good-quality image with a simple configuration. A pixel accumulates a charge by performing photoelectric conversion on incident light, and outputs a pixel signal corresponding to the charge. A vertical scanning circuit controls the pixel to cause the pixel to perform a shutter process of discharging an unnecessary charge accumulated in the pixel, a charge accumulation process of accumulating a charge generated through photoelectric conversion in a predetermined exposure time in the pixel, and a read process of outputting a pixel signal corresponding to the charge accumulated in the pixel in the charge accumulation process.
