In the disclosed optic signals processor, a term-by-term subtraction is made of the N homologous values of two series of values resulting from the integration of a light energy that selectively strikes respective photoactive pixels of a charge-coupled device. This charge-coupled device includes the following on one and the same component: an image zone having a first array of at least one line having 2N cells, each formed by a photoactive pixel integrating the light energy corresponding to one of the 2N terms of the two series of N values, by accumulation of a corresponding electrical charge, a transfer zone receiving the charges that have accumulated in the cells and including, for said line or for each of said lines, subtractor means successively receiving, at input, each of the two homologous charges that has been transferred from point to point along the line up to the transfer zone, and delivering, at output, a resultant charge proportional to the difference between the two charges applied at input, and reading means to detect said successive, resultant charges delivered by the transfer zone and to convert them into an electric voltage or current signal.
