Abstract
An image sensor including: a plurality of pixels, each pixel being capable of supplying an output signal representative of a quantity of light energy received from a time of beginning of a pixel integration phase; and a control circuit configured to, during a phase of acquisition of an image, successively select each pixel a number n of times during a same pixel integration phase, without resetting the pixel between the first and the last selection of the pixel and, for each selection of a pixel, compare the output signal of the pixel with a quantization threshold and read a binary signal representative of the result of the comparison.
