Patent ID: 10491815

Abstract:
An image-processing apparatus includes a computer configured to: detect a positional-displacement amount between low-resolution images including a standard image and at least one reference image that are acquired in a time series; generate a high-resolution combined image by positioning, based on the positional-displacement amount detected, pixel information of the reference image at a standard-image position and by performing combining thereof in a high-resolution image space; evaluate a positioning error caused by a resolution-enhancement magnification used when positioning the reference image in the high-resolution image space when generating the high-resolution combined image; and correct the high-resolution combined image based on the evaluation result, wherein the correcting of the high-resolution combined image combines a high-resolution correction image generated by applying a filter to the high-resolution combined image based on the evaluation result obtained, and the high-resolution combined image in accordance with combining ratios based on the evaluation result.
