Abstract
An image processing system includes an image sensor receiving light beams to output an output signal corresponding to a horizontal scan period and an image processor electronically connecting to the image sensor and including a signal interceptor and a calculating unit. The image processor transforms the output signal to generate a combining signal. The signal interceptor intercepts a first part of the combining signal corresponding to a first clock period of the horizontal scan period to obtain a first signal and intercepts a second part of the combining signal corresponding to a second clock period of the horizontal scan period to obtain a second signal. The calculating unit calculates the first signal and the second signal to obtain an image pixel data according to a differential calculation. The number of clocks of the first clock period is the same as the number of clocks of the second clock period.
