Abstract

We propose a novel method to synthesize high-resolution images by constructing a light field from image sequence taken with a moving video camera. Our method integrates multiple frames from video camera that partly captures the object by constructing a light field, which is quite different from general mosaic methods. In case of light field constructed straightforwardly, blur and discontinuity are introduced into generated images by depth variation of the object. In our method, light field is optimized to remove these blur and discontinuity, so that clear images can be generated. The optimized light field is adapted to the depth variation of object surface, but the exact shape of the object is not necessary. Extremely large resolution images that are impractical in the real system can be virtually generated from the light field. Results of the experiment applied to book surface demonstrate the effectiveness of the proposed method.
