Abstract
A process for correcting noise level of an image detector including photosensitive points arranged in rows and in columns. Within each row, the points are distributed into detector points and into corrector points. The detector points deliver a measurement value dependent on a luminous cue to which they are exposed. The corrector points deliver a dark value serving in the correction of the measurement values. Within at least one row, the detector points are distributed into at least two groups and the measurement values are corrected with a first or a second correction value depending on the group from which they originate. Such a process may find application to digitized-image detectors.
