Abstract: The present disclosure provides a time delay integration (TDI) sensor using a rolling shutter. The TDI sensor includes multiple pixel columns. Each pixel column includes multiple pixels arranged in an along-track direction, wherein two adjacent pixels or two adjacent pixel groups in every pixel column have a separation space therebetween. The separation space is equal to a pixel height multiplied by a time ratio of a line time difference of the rolling shutter and a frame period, or equal to a summation of at least one pixel height and a multiplication of the pixel height by the time ratio of the line time difference and the frame period. The TDI sensor further records defect pixels of a pixel array such that in integrating pixel data to integrators, the pixel data associated with the defect pixels is not integrated into corresponding integrators.

Abstract: There is provided a pixel circuit capable of outputting time difference data or image data, and including a first temporal circuit and a second temporal circuit. The first temporal circuit is used to store detected light energy of a first interval and a second interval as the time difference data. The second temporal circuit is used to store detected light energy of the second interval as the image data. The pixel circuit is used to output a pulse width signal corresponding to the time difference data or the image data in different operating modes.

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.
