METHOD FOR CONTROLLING A LIGHT-SENSITIVE DEVICE

摘要

The invention relates to a method for controlling a light-sensitive device comprising a matrix of light-sensitive points arranged into lines and columns. The invention can essentially but not exclusively be used in light-sensitive devices used for detecting X-ray images. The method includes a step (E2) of acquiring an image during which each light-sensitive point can accumulate a charge, and a step (E3) of reading said image. The reading step (E3) comprises a preliminary sub-step (E31) of converting the charges accumulated at the different light-sensitive points into analog signals representative of said charges, and a sub-step (E32) of processing the analog signals in order to obtain a digital image. According to the invention, the processing sub-step (E32) is repeated N times for a same light-sensitive point and for a same acquisition step (E2), with N being an integer greater than or equal to two, and the reading step (E3) comprises a sub-step (E35) of averaging the N signals processed per light-sensitive points in order to provide a single digital image per acquisition step (E2).
