Claim 0:
1. An image compensation device for an image for augmented reality, the image compensation device being combined with an optical device for augmented reality that includes: an image output unit configured to output augmented reality image light corresponding to an image for augmented reality; an optical means configured to transmit at least part of real object image light, which is image light output from a real object, therethrough toward a pupil of a user; and a plurality of reflective units disposed inside the optical means, and configured to transfer the augmented reality image light, output from the image output unit, to the pupil of the user by reflecting the augmented reality image light, the image compensation device comprising:
a compensation function determination unit configured to determine a compensation function for compensating luminance information of an observed image observed by the user through the optical device for augmented reality when an original image for augmented reality is output from the image output unit; and
a pre-compensated image information generation unit configured to generate pre-compensated image information for augmented reality based on the compensation function determined by the compensation function determination unit and original image information for augmented reality;
wherein the image output unit outputs pre-compensated augmented reality image light corresponding to the pre-compensated image information for augmented reality generated by the pre-compensated image information generation unit, and the plurality of reflective units transfer the pre-compensated augmented reality image light, output from the image output unit, to the pupil of the user by reflecting the pre-compensated augmented reality image light.
