Abstract: For each current image output from a pixel matrix, the digital words relative to at least one masked line of the matrix are processed to generate a current correction digital code. From this code, a black level compensation signal is generated and applied as an offset control on pixel signal amplification. If the current correct digital code does not differ from the code calculated for a previous image output by a predetermined amount, then the code for the previous image is instead used to generate the black level compensation signal.

Abstract: A chainable adder receives bits (A, B, C) to give complementary sum outputs (SO, SO*) and carry outputs (CO, CO*). A first stage has differential pairs (P1, P2, P3) receiving bits (A, B, C), respectively, and complements (A*, B*, C*), respectively. The pairs have common output arms and are powered by an identical current (I). First and second output arms include resistors (R1, R2, R3) and (R4, R5, R6), respectively, connected-in-series to a reference potential (M). The resistors define intermediate nodes (A1, A2, A3) in the first arm, (B1, B2, B3) in the second arm. Carry outputs are taken at nodes (A2, B2). A second stage has differential pairs (P4, P5, P6) whose inputs are connected to nodes (A1, B3) for pair (P4), (A2, B2) for pair (P5), and (A3, B1) for pair (P6). Pairs (P4, P6) each have a common arm with the pair (P5) and a non-common arm. The sum outputs are constituted by a combination, according to an “OR” function, of logic states on the non-common arm of one of pairs (P4, P6) and on the common arm of another of pairs (P4, P6).
