Classification: CPC H | IPC H

Claim 10:
11. A TDI CMOS image sensor, configured to capture an image frame using a rolling shutter and move with respect to a scene in an along-track direction, the image sensor comprising:
a first pixel array and a second pixel array, each comprising multiple pixel columns, each of the pixel columns comprising multiple pixels arranged in the along-track direction, and two adjacent pixels of each of the pixel columns having a separation space therebetween, wherein the separation space is a summation of a pixel height in the along-track direction and a multiplication of the pixel height by a time ratio of a line time difference of the rolling shutter and a frame period of capturing the image frame,
wherein the first pixel array and the second pixel array are arranged along the along-track direction, and each of the pixel columns of the first pixel array is aligned with a corresponding pixel column of the second pixel array configured to sequentially cross a same position of the scene.
