Claim 0:
1. A color calibration display apparatus, comprising:
a frame which is in a form of a helmet or goggles having a frame structure through which light is to enter in a state of being worn on a head of a user;
a display projector configured to output image light such that augmented reality image information is to be provided to the user on an optimized screen along with a transmitted and visible real world;
a projection optical system installed to be attached to one side of the frame and configured to generate and transmit an output augmented reality image signal to the display projector;
a controller configured to control brightness of an augmented reality image, which is to be viewed by being projected by the display projector, to be adjusted according to illuminance detected by an illuminance sensor;
a power supply configured to supply power for augmented reality driving of the color calibration display apparatus; and
a color calibration display configured to, when the image light generated by the display projector is projected onto the projection optical system and reflected by the projection optical system to enter eyes of the user, change color in response to an adjustment of an amount of light incident from an outside to recognize the augmented reality image information,
wherein the controller is configured to provide an optimized screen having optimized visibility simultaneously using a degree of a change in color of the color calibration display, which is configured to change color according to an amount of ultraviolet light, and an illuminance value detected by the illuminance sensor.
