Abstract (in Japanese) (See Japanese page) 
(in English) We study the imaging system for reconstructing high-spatial resolution image using high frame-rate images from an image sensor. We adopt the spatial gradients with low estimated errors by predicting the motion vectors of the current frame from the motion vectors of the previous frame. In the case of applying the high frame-rate images, it is assumed that the temporal correlation between motion vectors is high. Therefore, using the spatial gradients, we can improve the accuracy of the motion estimation in the high frame-rate images. In this paper, we propose new method which uses 2 frame images for the estimation of spatial gradients. And we show the method of increasing spatial resolution using high frame-rate images as an application of the proposed method.
