Device for an array (1) of photo diodes arranged in matrix, which are integrated onto the same semi-conductor substrate (4) as a picture processor (3) connected to the photo diodes, where the picture processor (3) is of a type allowing parallel signal processing, such as picture transformation of the picture signals coming from the photo diodes, said device further including a digital circuit (17) arranged on said substrate (4) and connected to the processor (3) characterized in that said digital circuit (17) is arranged to deterine the number and/or the position and/or the sum of the positions of selected picture elements from the processed picture, said elements having been found, by means of the picture processor, to fulfill a pre-determined condition, whereby a reduction of picture data flow from said substrate is achieved. |
