摘要： The present invention relates to a method of driving a photosensitive device comprising a matrix of photosensitive pixels distributed at the intersections of rows and columns of the matrix. The invention relates more particularly to the control of such devices used for the detection of radiological images. The method consists in subjecting the matrix to an image cycle that includes a reset phase prior to an image acquisition phase. The rows of the matrix are distributed in several groups, and during the reset phase, the method consists in resetting all the rows in any one group simultaneously and in resetting each group of rows in succession.

摘要： A process for controlling a photosensitive device including at least one photosensitive point with a photodiode connected to a switching element. The process submits the photosensitive point to successive imaging cycles. Between a first imaging cycle and a second imaging cycle, the process produces a holding phase terminating at the start of the second imaging cycle. During this holding phase, whose duration is equal to several equal time intervals that are as short as possible, the photosensitive point is exposed to an optical flash at the start of each time interval. Between successive optical flashes, the photodiode is reverse biased. The junction region between the photodiode and the switching element has substantially the same potential at the end of each time interval.
