Abstract
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.
