A method for reading from a cell of a network of photosensitive cells arranged in rows and in columns, each cell being adapted to providing an image voltage or a reference voltage, comprising the steps of charging, simultaneously for all the cells in the row of said cell, at least one capacitor with a resulting charge which is a function of the difference between a reference current and an image current respectively corresponding to the conversion, by an amplifying factor greater than one, of the reference voltage and of the image voltage, and measuring for the cell column the capacitor charge.
