Abstract: The invention relates to an image generating device (11), comprising:—a light source (12),—a light modulator (13) or a diffuser adapted to display an image on an output face side, and—an auto-stereoscopic filter (14) of which an input face is turned towards the output face of the light modulator or the diffuser. According to the invention, the auto-stereoscopic filter extends opposite only a portion of the output face, and an image plane offset panel (15) is provided, which is located only opposite the remaining portion of the output face.

Abstract: A head-up display includes an image-generating system, and a projecting optical system that includes a common mirror and a folding mirror. The image-generating system is configured to emit a first source light beam and a second source light beam that pass through an image plane. The projecting system also includes an element for redirecting beams by diffraction that deflects the first source light beam downstream of the image plane into a first intermediate beam directed toward the common mirror. The folding mirror is configured to reflect the second source light beam downstream of the image plane into a second intermediate beam directed toward the common mirror. The common mirror is configured to intercept and project the first intermediate beam and the second intermediate beam to form a first virtual image at a first projection distance and a second virtual image at a second projection distance.
