Interactive contents with high quality images is now widely available. One way to make this content more realistic is to display it covering the viewer's entire field of view. The problem is that the view-angle of the existing content is not adequate for large display surfaces because the content is designed to be displayed on household TV monitors with a target view-angle of approximately 30 degrees. To achieve realism, we have to enlarge the view-angle of these images in real-time. Therefore, we developed a technique that reconstructs wide view-angle images by extracting peripheral images from time-series image frames in real-time. A simple 3-D model approximating target scenes enables real-time processing and a reduction of the uncomfortable feeling that happens when reconstructed peripheral images are distorted. We used our method with actual game content and objectively and subjectively evaluated the image quality and processing time. The evaluation results demonstrated that our technique effectively enhanced the fun of content itself.
