FIELD: optical devices.
SUBSTANCE: group of inventions relates to a control device for a device of onboard projection indication (head-up display, hereinafter – HUD). The control device contains image generation unit (8), optical element (13), positioning device (11) and camera unit (12). Optical element (13) is made with the possibility to deflect radiation of image generation unit (8) in the direction of windshield (1) and, by means of this, irradiate HUD area (B) of windshield (1) to generate virtual image (7). Positioning device (11) is made with the possibility to fix windshield (1) in the given location relatively to optical element (13). Camera unit (12) is made with the possibility to capture virtual image (7) through windshield (1) from different eye positions. Optical element (13) is configured in such a way that complete virtual image (7) is in the range (Δd) of the sharpness depth of camera unit (12).
EFFECT: providing an improved control device for a device of onboard projection indication (HUD) that can also be used with contact analogue HUD.
