Image compensation device for image for augmented reality

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, 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 a 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 pre-compensated augmented reality image light is transferred to a pupil of the user through the optical device for augmented reality;
• wherein the optical device for augmented reality includes a plurality of reflective units configured to 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;
• wherein the compensation function determination unit determines the compensation function based on a shape of the reflective units, an arrangement of the reflective units and an eye point spread function (PSF);
• and
• wherein the eye point spread function PSF(x,y) is a two-dimensional spatial distribution function of intensity values of an image formed on a retina when a point light source at a predetermined distance away from the user's pupil is observed.
