Abstract: There is provided a pixel circuit for performing analog operation including a photodiode, a first temporal circuit, a second temporal circuit and an operation circuit. Within a first interval, the photodiode detects first light energy to be stored in the first temporal circuit. Within a second interval, the photodiode detects second light energy to be stored in the second temporal circuit. Within an operation interval, the first temporal circuit outputs a first detection signal having a first pulse width according to the first light energy and outputs a second detection signal having a second pulse width according to the second light energy for being calculated by the operation circuit.

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.
