Abstract
A method of driving a photosensitive device including a matrix of photosensitive pixels of the type produced in particular by techniques for depositing semiconductor materials. The method may be particularly directed to the driving of such devices used for radiological image detection. The method subjects the photosensitive pixel during a read phase to a cycle of successive images including a useful image preceded by at least one offset image taken at an initial instant. A correction is applied to the useful image, the correction being based on the offset image taken at the initial instant and based on the time separating the useful image from the offset image taken at the initial instant.
