Method and system for selectively adjusting pixels, in an optical module, in order to amend geometric defects due to manufacturing tolerances

Abstract

A luminous motor-vehicle system including an optical module and aims to compensate for undesirable movement or deformation effects caused by the manufacturing tolerances of the optical portion. The module includes an imaging device provided with a pixelated spatial modulator, which is illuminated by a source, and a projecting optic. A control unit for controlling the modulator receives first display commands that are representative of an image to be projected. This unit converts each first display command into a second display command taking into account correction parameters, which are predefined on the basis of an identification of geometric defects specific to the projecting optic. The control unit controls the modulator, which may be a digital micromirror device, depending on the second display commands in order that the image actually projected by the imaging device corresponds to the image to be projected.
