| Abstract(in English) | The motion blur caused by aperture time can be improved by reducing the rate of a camera shutter opening. However, with reducing the aperture ratio, the "jerkiness" which is another artifact about the movement perception appears. We evaluated the jerkiness of natural images for various frame rates and aperture ratios. The subjects consisted of nonspecialists. In to 240 frame/sec, we got the result that there was a picture quality improvement by raising a frame rate. |
