Claim 14:
15. The method according to claim 14, wherein the image readout method is implemented by an image sensor comprising:
a pixel array including a plurality of pixels arranged in rows and columns; and
a plurality of readout conversion circuits, each of which corresponds to at least one column of pixels in the pixel array;
wherein a readout conversion circuit comprises:
the comparison circuit connected to an output terminal of corresponding column pixels, wherein the comparison circuit is for comparing the output signal of the column pixels with the ramp signal to output the pulse signal to obtain the first output signal and the second output signal;
the selection module connected to the comparison circuit, wherein the selection module is for selecting the first output signal of the comparison circuit during the first sampling count, and selecting the second output signal of the comparison circuit during the second sampling count;
the counter connected to an output terminal of the selection module, wherein the counter is for counting according to the first output signal and the second output signal of the comparison circuit to obtain the total quantization value of the first sampling count and the second sampling count, so as to obtain the actual signal quantization result according to the total quantization value.
