Abstract
An image sensor with a distance sensing function and an operating method thereof are provided. The image sensor includes a pixel array, a cluster analog to digital converter readout circuit, and a column readout circuit. The pixel array includes a plurality of sub-pixel groups arranged in an array. The plurality of sub-pixel groups are spaced apart from each other by a circuit layout area. The cluster analog to digital converter readout circuit is disposed in the circuit layout area of the pixel array. A distance sensing pixel of each of the plurality of sub-pixel groups is configured to perform time-of-flight ranging. The column readout circuit is disposed adjacent to the pixel array. A plurality of image sensing pixels of each of plurality of the sub-pixel groups are configured to perform image sensing.
