Zusammenfassung:A method for calibrating a light module including a set of light-emitting elements, the method including powering the light-emitting elements so as to obtain an image projected by the light module, the projected image including a set of pixels, each pixel corresponding to at least one subset of at least one light-emitting element of the light source; for each pixel of the projected image, comparison of a difference between a light intensity of the pixel with a predefined light intensity of a corresponding pixel of a reference image, with a threshold; in the case where the difference is above the predetermined threshold, determination of a modified power supply value of at least one first light-emitting element of the subset corresponding to the given pixel; and storage, in a memory of the light module, of the modified power supply value in association with an identifier of the subset including the first light-emitting element.
