Abstract
The invention provides a photosensitive device with locally adjustable exposure time, wherein means provide local modification of the integration time, for some detectors, as a function of the lighting received by each detector. In FIG. 1, these means are formed by a shift register with a series input and parallel outputs, by MOS transistors and by charge removal diodes.
