The present invention concerns a device for controlling photosensitive sensor image taking equipment, which comprises at least one logic assembly transmitting the image taking, transfer of signals emitted by the photosensitive elements from the integration zones to the reading assembly then to at least one memory register, the image taking being initiated at the desired moment, the durations of the image taking being adjusted as to the conditions of the subjects with respect to the light, in order to obtain optimal images, the actuation and the reading duration being controlled by the logic assembly, the subsequent successive transfers being performed once the preceding operations have been completed and when the delays inherent in the constitutive elements allow it.

The invention concerns a process and an apparatus for automatic inspection of transparency contrast, consisting of illuminating the body of a container transversely to its axis (8), placing the container (3) against the light simultaneously with the aid of two charge transfer cameras, the sighting axes (11) of which are off-set angularly, of eliminating with the aid of an electronic window appropriate for each type of container, all signals originating in elementary points of the photosensitive matrix devices of said cameras (10) located outside the window, of analyzing successively each elementary point of the window by taking into account a predetermined number of immediately surrounding elementary points, of comparing the electric level of each elementary point weighted in this manner with a reference level pre-established for each type of container and of actuating the rejection of the container being inspected when the number of elementary points detected out of reference is higher than a predetermined number. Application in particular to the inspection of bottles.
