The invention relates to a method for controlling a luminous device of a motor vehicle arranged to emit a pixelated light beam in a preset emission region. The method includes receiving an instruction to emit a desired pixelated luminous function for each of the luminous modules. The instruction for creating a digital image forming one segment of the desired pixelated luminous function in a frame corresponding to the preset emission region of the luminous module, the digital image being independent of the types of light sources and of optical device of the luminous module. The method further correcting said created digital image depending on the types of light sources and of optical device of the luminous module. The method additionally emitting, with the luminous module, into the preset emission region, a pixelated light beam corresponding to the corrected digital image.
