Abstract
There is provided an optical sensor including a pixel matrix and a readout circuit. The pixel matrix includes multiple pixels arranged in a matrix, and each of the multiple pixels outputs temporal difference pixel data. The readout circuit sequentially reads the pixel matrix using a readout block, and performs the hybrid difference calculation on the temporal difference pixel data of pixels within the readout block. Accordingly, the output of the readout circuit is the data accomplishing temporal difference and spatial difference.
