The disclosure concerns the reading of the photocharges generated by the illumination of a matrix of photosensitive dots. The dots are formed by a photosensitive diode in series with a reading diode, all between a row and a column of the matrix. To reduce the reading errors, there is provision to illuminate the photosensitive dots with a constant illumination which gets added to the illumination to be measured, thus creating driving charges that get added to the useful charge and facilitate its transfer to a reading register.
