Abstract (in Japanese) (See Japanese page) 
(in English) As the screens of home TVs become larger, the number of viewers, who feel a sense of unpleasantness from shaking images may increase. In order to find and revise the images, which make viewers unpleasant, efficiently at the production stage, the authors have been developing a technique which automatically estimates the unpleasantness degree invoked by shaking images. However, it was found that the actually measured unpleasantness degree for ordinary images in broadcasting program is often significantly lower or higher than the estimated one using the developed method so far. The authors considered the causes of the occurring errors, and thought out a new method to reduce the estimation error. As a result of psychological estimation experiments with 96 “On Air” images, it was confirmed that the new method has an effect to reduce estimation error by approximately 30%.
