A method and system for reducing the effects of glare in a system that comprises a picture generating unit or projector, such as a holographic projector. For example, the system may be a head-up display (HUD), which is configured to display a picture to a viewer, without requiring the user to look away from their usual, or required, viewpoint. For example, the HUD system may be comprised within a vehicle. The glare in the system may be caused by light, other than the light of the picture, being incident on a surface comprising a screen or a window, through which the user looks at their usual, or required, viewpoint. For example, the surface may comprise a windshield in a vehicle. The light that causes the glare may be ambient light, such as sunlight. In particular, the method and system are provided for reducing the effects of glare in a system that comprises a waveguide in conjunction with the picture generating unit. The waveguide may be operable to act as an exit pupil expander.
