1. A method of qualification of an image sensor having images in the form of pixels, comprising the steps of: determining the maximum limit of the number of bad pixels in a given area of the image that can be processed; defining a window having the format of the area determined, establishing a cartography of the pixels formiing an image delivered by the sensor which indicates the locations of bad pixels; checking whether a part of the cartography that may contain the window has a set of bad pixels incompatible with the maximum limit; and qualifying or rejecting the sensor depending on the control result.
