Patent number: 4553168Abstract: 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.Type: GrantFiled: December 6, 1983Date of Patent: November 12, 1985Assignee: Thomson-CSFInventors: Jacques Chautemps, Pierrick Descure

Patent number: 4477835Abstract: 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).Type: GrantFiled: March 9, 1982Date of Patent: October 16, 1984Assignee: Thomson-CSFInventors: Jean L.
