Abstract (in Japanese) (See Japanese page) 
(in English) The performance of general purpose computers is increasing rapidly, and now they are capable of running video processing applications. However, on general purpose operating systems, real-time video processing is still difficult because there is no guarantee that enough CPU resources can surely be provided. A pseudo real-time video processing library RaVioli has been proposed for solving this issue. RaVioli conceals two resolutions, frame rate and number of pixels, from programmers and provides a dynamic and transparent resolution adjustability. Using RaVioli, pseudo real-time video processing can be achieved easily, but output precision may be extremely roughened for reducing processing load. To solve this problem, we propose a method to divide a whole video frame
into several sub-frames, and process each sub-frame with an appropriate resolution or precision. We also propose a method to automatically parallelize the processing on RaVioli. We aim to implove the processing precision with these methods.
