Abstract :
We have been investigating a high-speed image-based rendering system. In this area, most of the conventional systems sacrifice spatial or temporal resolution for a heavy amount of input images. When the system uses a camera-array on its input, this problem is more obvious. However, the required image data for the rendering are only a portion of them, determined by the position of the imaginary-view. We propose an image based rendering system, which uses pixel independent random access image sensors to eliminate the bottleneck of the conventional systems. We have developed a prototype of a CMOS image sensor, which has 128 × 128 pixels. We verified that the prototype chip readouts externally selected pixels at 60 frames/second
