Abstract
Provided is an image sensor circuit, including a pixel array and a plurality of different control circuits. The pixel array comprises a plurality of pixel circuit groups arranged in an array. Each pixel circuit group comprises a plurality of pixel circuits that generate corresponding sensitivity values over exposure duration. The pixel circuits include a first quantity of first pixel circuits, and a second quantity of second pixel circuits. The plurality of different control circuits are respectively coupled to different pixel circuits to control the exposure duration thereof with different transmission signals. The different control circuits are also set to control different pixel circuits to output photo-sensed values at different frame rates. The image sensor circuit periodically generates the pixel value of each pixel circuit group according to first and second exposure durations, first and second frame rates, and first and second light sensitivity values of each pixel circuit group.
