Electronic selector device (100) for an electro-optical sensor provided with a plurality of light-sensitive elements, or pixels, (10) arranged in rows and columns so as to form a matrix (27). The device comprises decoders (60) implemented as four shift registers (55, 56, 57, 58) comprising memory cells (59). A first (55) and a second (56) of the shift registers identify any one whatsoever of the pixels (10) of the matrix (27). The function of the third (57) shift register is to vary the integration time of the light signal, and the function of the fourth (58) shift register is to regulate the size of the image to be acquired. Each of the cells (59) is selectively enabled in a dynamically programmable way so as to modify the structure and the operation of the shift registers (55, 56, 57) according to input signals serially introduced into the fourth register (58) in order to select and read only a sub-frame of the total of the pixels (10) in the matrix (27).
