ABSTRACT The invention relates to a device for an array (1) of photo diodes arranged in amatrix, which are integrated onto the same semi-conductor substrate (4) as a picture processor (3) connected to the photo diodes. The picture processor (3) is of a programmable type allowing parallel signal processing, such as a picture transformation of the picture signals coming from the photo diodes. The characteristic of the invention is that the device includes a digital circuit (17) of combinatorial or sequential type connected to the processor (3). This is arranged on said substrate and designed to determine the number and/or the position and/or the sum of positions of the picture elements which the photo diodes (1) and the picture processor (3) have established to fulfil a digital criterion.
