Abstract
The present disclosure relates to an image sensor including: a plurality of pixels, each including a first photodiode coupled to a first capacitive charge storage node by a first transistor, and a second photodiode coupled to a second capacitive charge storage node by a second transistor; and a control circuit configured so as to, during a phase of acquisition of a value representative of the illumination level of a pixel: acquire a first output value representative of the illumination level received by the first photodiode during a first uninterrupted integration period; and acquire a second output value representative of the illumination level received by the second photodiode during a second integration period divided into a plurality of separate sub-periods.
