摘要： In a CCD type photosensitive device, the charges produced in two consecutive columns of pixels are transferred into different reading registers: the charges from the first column are loaded into the first register and the charges from the second column travel through the first register to be loaded into the second register. The two reading registers are controlled by independent potentials during the step for the loading of these registers. The device makes it possible to increase the efficiency of the transfer between the two reading registers, especially when the registers are of the type working in a two-phase mode.

摘要： An improved line-transfer photosensitive device and particularly a device which operates with a double drive charge comprises on at least one semiconductor substrate a photosensitive region made up of M lines of N photosensitive points. The photosensitive points of the different lines are connected in parallel by means of conductive columns to a line memory which carries out at least the transfer of the signal charges integrated on any one line of the phtosensitive region to a read register consisting of a charge-coupled shift register of the volume transfer type. The line memory is formed on a semiconductor substrate region having an impurity implantation of opposite type with respect to the substrate in order to produce a volume charge transfer. The region in which the line memory is formed has a dopant concentration which is lower than or equal to that of the region in which the shift register is formed.

摘要： The storage capacity of the photosensitive points is increased during the time interval starting after the evacuation of the parasitic charges from the conductive columns to the memory and finishing by the transfer of signal charges from a row of the columns to the memory. Thus, even the overilluminated photosensitive points do not overflow onto the columns.

摘要： Use is made of a row memory and a read register, in which charge transfer takes place in volume. The threshold voltage of the negative feedback amplifiers is adjusted so that the operating point of the assembly constituted by each amplifier, the diode and the gate of the memory to which it is connected is located in the high gain zone of the transfer characteristic of the amplifier. It is possible to adjust the threshold voltage by an enhancement in its own type of impurities of the zone of the substrate located beneath the gate of one of the MOS transistors constituting the amplifier.

摘要： In order to modulate the sensitivity of a photosensitive device by modulating the integration time, a first reading of each line of a photosensitive zone of the device is followed by a second reading at an adjustable time interval. The charges resulting from the first reading operation are removed to the drain while the parasitic charges and the signal charges resulting from the second reading operation are transferred to the read register at the same time. Modulation of the time interval which elapses between two readings of one line is carried out by varying the time which elapses between the injection of one drive pulse into the two registers which control respectively the first reading and the second reading of the lines.

摘要： The present invention provides a device for reading a matrix of photosensitive detectors by line transfer with feedback, wherein means provide feedback of a part of the video signal from a line of the matrix which is read to a stage for series injection of a drive charge at the input of a register providing reading successively of each line of detectors of the matrix. Thus the value of the drive charge is modulated which is intended to be added to the video signal of the line of the matrix which will then be read, such modulation being directly proportional to the video signal of the line which is read and dependent on the transfer inefficiency of the device.
