Abstract:
1. A method of controlling a photosensitive device comprising a matrix of photosensitive points organized in rows and columns, the method comprising: acquiring an image in the course of which each photosensitive point is able to accumulate a charge and reading said image, the reading step comprising: a prior sub-step of converting the charge accumulated at the various photosensitive points into analog signals representative of this charge; and a sub-step of processing these analog signals making it possible to obtain a digital image, wherein the processing sub-step further comprises a multiplexing of the analog signals so as to provide in series a multiplexed signal for each processing sub-step, and wherein the processing sub-step is repeated N times for a single exposure, for each photosensitive point and for each acquisition step, with N an integer greater than or equal to two, and wherein the reading step comprises a sub-step of averaging the N signals processed per photosensitive point so as to provide a single digital image per acquisition step.
