A damaged portion of a vehicle windshield in an area near a transparent display (TD) of a head up display (HUD) may be treated with a resin. The treated portion may introduce brightness artifacts into an image projected onto the TD. To compensate images projected onto the TD for the brightness artifacts, first pixel intensity adjustment values are received via a touchscreen. Pixels of a reference image are adjusted in accordance with the first pixel intensity adjustment values to provide a reference compensated image which, when projected by a projector of the head up display (HUD) system onto the TD, counters effects of spatially varying reflectance properties of treated portion of the windshield which would otherwise appear were the reference image displayed on the TD without compensation.
