Abstract
Official abstract text for this publication.
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 (E 2 ) of acquiring an image during which each light-sensitive point can accumulate a charge, and a step (E 3 ) of reading said image. The reading step (E 3 ) comprises a preliminary sub-step (E 31 ) of converting the charges accumulated at the different light-sensitive points into analog signals representative of said charges, and a sub-step (E 32 ) of processing the analog signals in order to obtain a digital image. According to the invention, the processing sub-step (E 32 ) is repeated N times for a same light-sensitive point and for a same acquisition step (E 2 ), with N being an integer greater than or equal to two, and the reading step (E 3 ) comprises a sub-step (E 35 ) of averaging the N signals processed per light-sensitive points in order to provide a single digital image per acquisition step (E 2 ).
First claim
Opening claim text (preview).
The invention claimed is: 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-s…
