1. An apparatus comprising:
a processor;
a display panel including a touchscreen;
a memory storing processor executable instructions that configure the processor to:
receive via the touchscreen, first pixel intensity adjustment values; and
adjust pixels of a reference image in accordance with the first pixel intensity adjustment values to provide a reference compensated image which, when projected by a projector of a head up display (HUD) system onto a transparent projection surface, counters effects of spatially varying albedo of the transparent projection surface on the reference image when the reference image is displayed on the transparent projection surface, wherein the spatially varying albedo is introduced via a physical abnormality in the transparent projection surface due to damage and/or repair.
