A multilinear charge transfer array is provided formed by N lines of P photosensitie detectors. Each photosensitive detector is connected directly by a connection to a demultiplexing and reading system, the signals obtained at the output of the array being fed to a processing device external to the array. The demultiplexing system comprises a charge transfer shift register with N.times.P stages, the connections between each detector and the corresponding input of the register being provided so that the detectors of the same rank are connected to contiguous inputs.

A gate structure for integrated circuits and more especially for photosensitive charge-transfer devices comprises elements of the gate-insulator-semiconductor type. The gate structure is constituted by a thin film-layer of transparent or semi-transparent conductive material covered with a layer of compatible insulating material having a refractive index higher than 1.5.

The charges induced by the light image to be scanned are integrated cyclically. During each integration cycle, the total amplitude of the signal corresponding to said image is calculated. The calculated amplitude is compared with a threshold amplitude value which is a function of a saturation value which is itself fixed by the amplitude of a periodic bias voltage applied to the device. The amplitude of the potential wells created by said bias voltage is modulated as a function of the result of said comparison. The invention is applicable to solid state TV cameras, e.g. for use in low light.

A charge transfer photosensitive device, having a plurality of photosensitive zones (20) fabricated on a single conducting substrate, and having N lines and M columns, and insulated from one another. In the photosensitive zones electrical charges are created depending upon light received. Each of these zones is formed by a MOS capacitance (3) and a charge collecting diode (8). A plurality of reading diodes (5) read the charges collected in the photosensitive zones; and a screen grid (4) is placed between the reading diodes (5) and the photosensitive zones (20).
