Abstract
Long and short exposure time pixel information are input to pixel information. A long exposure time image set with the pixel values assuming all of the pixels have been exposed for a long time and a short exposure time image set with the pixel values assuming all of the pixels have been exposed for a short time are generated. A point spread function corresponding to the long exposure time image is computed as a long exposure time image PSF. A corrected image is generated using the short exposure time image, the long exposure time image, and the long exposure time image PSF. The corrected image is generated as a wide dynamic range image utilizing the pixel information for the long and short exposure time image. Utilizing the pixel information for the short exposure time image with little blurring, makes the corrected image a high quality corrected image with little blurring.
