| Research Abstract |
A new super-resolution reconstruction method has been developed. This method can synthesize a high resolution image whose resolution is beyond the specific resolution of the image sensor. It can be applied when there is image blur in the optical system. To generate a high resolution image, the method utilizes a series of images observed by the image sensor while moving its position by a shift amount smaller than the pixel of the image sensor. The method has been applied to the satellite remote sensing images and thermal images, and it succeeded in achieving images whose resolution is about five times higher than that of the observed images. A sensor architecture for super-resolution reconstruction of the satellite remote sensing image was also proposed.
