Abstract
The invention relates to image sensors and more specifically the generation of control signals for pixels and readout circuits. The sequencing circuit which produces these signals comprises: a programmable memory (MEM) containing binary words (M, M, M, etc.) in which each word comprises a group of several bits of position 1 to N, and in which the position i of a bit in a word corresponds to the position i of a respective control signal; a memory controller (CTRL_MEM) for extracting from the memory at a determined rate the words located at successive addresses of the memory from a start address to an end address; and a control signal generation circuit (GEN_TIMING) establishing each control signal of position i from the succession of bits of respective position i that are extracted from the memory by the controller, the control signal reproducing the successive values taken by the bit of position i at the clock rate.
