METHOD FOR CONTROLLING A PHOTOSENSITIVE DEVICE FOR PRODUCING GOOD QUALITY IMAGES

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.
