The glare-illusion is a well-known illusory perception that a region appears brighter than its actual luminance when surrounded by a gradation of luminance. Its illusion has the potential to gives strong shine perception than the naive enhancement in projection display. This paper proposes a novel projection-based perceptual shine enhancement method based on the glare illusion to break manipulation limitations caused by hardware performance. Our proposed method generates an overlay illumination pattern which has gradation surrounding the specular region to induce glare illusion. Through the experiments, we confirmed the proposed method gives a brighter perception than naive contrast enhancement. The remaining issue is a study on the optimal gradation width for each scene.
