A CMOS image sensor including a plurality of pixels, each including: a photodiode; a sigma-delta modulator of order p, p being an integer greater than or equal to 1, capable of delivering a binary digital signal representative of the illumination level of the photodiode; and a configurable connection circuit enabling to couple the sigma-delta modulator of the pixel to a sigma-delta modulator of another pixel, so that the modulators of the two pixels form with each other a sigma-delta modulator of order greater than p. |
