The present invention relates to an image matrix sensor, wherein in a matrix image sensor (100) comprising a plurality of independent detection structures (1 ij ) associated with corresponding pixels, each of the independent detection structures (1 ij ) is a solar cell mode. A photo diode 3 ij having at least one operating range at; A first amplifier stage (4 ij ), which is permanently powered, receives as input an voltage dependent on the voltage of the photodiode (3 ij ) and comprises the operating range; And a; and wherein the first amplifier stage (4 ij) a second amplifier stage (5 ij), and linked to the output, wherein the first, depending on whether the output of the amplifier stage the read power is supplied by any other means. |
