Claim Text:
1. An image distortion compensation device for compensating image distortion on image traversing safety goggles comprising: an image distortion estimation unit to preliminarily estimate image distortion based on spectral characteristics of the safety goggles; and a color correction unit to perform color correction to compensate the estimated image distortion with respect to an image to be displayed on a display unit; and wherein the spectral characteristics of the safety goggles comprise light absorbance of the safety goggles according to wavelength, wherein the image distortion estimation unit determines whether or not compensation of image distortion is possible through the color correction, wherein the image distortion estimation unit determines that compensation of the image distortion is impossible through the color correction when, among colors used for the image to be displayed on the display unit, a color not represented in the image to be displayed on the display unit to which light absorption effects of the safety goggles are applied is present.
