Image processing system and endoscope using the same

An endoscope, comprising:

• an insert tube;
• a handle, one end of the handle connecting to one end of the insert tube;
• an image processing system comprising an image sensor and an image processor, the image sensor receiving a plurality of light beams to output an output signal corresponding to a horizontal scan period, the image processor electronically connecting to the image sensor and comprising a signal interceptor and a calculating unit, the image processor transforming the output signal to generate a combining signal, the signal interceptor intercepting a first part of the combining signal corresponding to a first clock period of the horizontal scan period to obtain a first signal, and intercepting 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 calculating the first signal and the second signal to obtain an image pixel data in accordance with a differential calculation, wherein, the number of clocks of the first clock period is the same as the number of clocks of the second clock period, and the image processor is disposed in the handle;
• and
• a distal end, one end of the distal end connecting to the other end of the insert tube, the image sensor being disposed in the distal end.
