A device is provided for generating a pixel of an image, including a rotatable disk element arranged to be selectively rotatable between: a maximum luminance position, in which it blocks a minimum portion of a light path; a minimum luminance position, in which it blocks a maximum portion of the light path; and at least one intermediate luminance position, in which it blocks an intermediate portion of said light path; whereby the position of said rotatable disk element determines, at least in part, the luminance and/or the color of the pixel.
