Abstract (in Japanese) (See Japanese page) 
(in English) In noise evaluation of image sensor, it is important to establish the visual noise level, which is a noise evaluation value using the visual system. In a still image, there are some methods using visual spatial frequency characteristics. We can’t use the methods because the visual noise level can vary depending on the frame rate in a moving image. There aren’t any methods of noise evaluation for moving image sequences. In this paper, we show a dependence on frame rate using visual temporal frequency characteristics, and propose a new method of noise evaluation for moving image sequences. The proposed method showed good performance in the evaluation experiment.
