Abstract: A head-up display for a vehicle. The head-up display comprises a projector and processor. The projector is arranged to project image content such that it is visible from an eye-box. The processor is arranged to receive captured images of a scene visible from the eye-box. The processor is arranged, at a first time to: detect a first object in a scene and instruct the image projector to project an icon (e.g. computer graphic) that appears, from the viewing position, to be coincident with the first object. The processor is further arranged to, at a second time later than the first time to: detect a second object in a line of sight from the eye-box position to the first object and instruct the image projector to change the visual appearance of the projected icon in response to the detection of the second object.
