Claim 11:
12. The image sensor according to claim 11, wherein during the first sampling count, when the selection module outputs a first level, the counter starts to count down or count up, and a count value of the counter is codex, during the second sampling count, when the selection module outputs the first level, the counter continues to count down or count up based on the first sampling count, and the count value of the counter is code_total, code_total=codex+codey, wherein the code_total is the total quantization value, the codex is the count value of the first sampling count, the codey is an actual count value of the second sampling count, wherein the preset time period is TA, the corresponding preset quantization result is code_TA, the reset signal quantization result is code_rst, code_rst=code_TA−codex, and the actual signal quantization result is code_sig, code_sig=code_total−code_TA.
