Abstract
An image processing system includes an image sensor circuit. The image sensor circuit is configured to obtain an image using a type of shutter operation in which an exposure pattern of a pixel array is set according to exposure information that changes over time based at least partially on charge accumulated in at least a portion of the pixel array. An image sensor circuit includes a pixel array and one or more circuits. The one or more circuits are configured to update exposure information based at least partially on one or more signals output from the pixel array, and to control an exposure pattern of the pixel array based on the exposure information. A pixel circuit includes a first transistor connected between a photodiode and a sense node, and a second transistor connected between an exposure control signal line and a gate of the first transistor.
