Abstract
According to embodiments of the present invention, an image sensor is provided. The image sensor includes a plurality of photodetectors, a plurality of pixel circuits, each pixel circuit including a first transistor, wherein the first transistor is coupled to a respective photodetector of the plurality of photodetectors, and an interconnection bus, wherein, in an imaging mode, the plurality of photodetectors are configured for imaging, and wherein, in a sensing mode, the plurality of photodetectors are configured to detect ambient light condition, and wherein the interconnection bus is connectable between the plurality of pixel circuits and an ambient light readout circuit to carry signals corresponding to the detected ambient light condition from the plurality of photodetectors through the first transistors to the ambient light readout circuit. According to further embodiments, a display including an image sensor and a method of controlling an image sensor are also provided.
