Abstract
When distortion correction is performed by dividing a distortion correction target region (Atc), a distortion-corrected division region image (D) is generated by performing the distortion correction on each division region of the distortion correction target region and a distortion-corrected image (D) is generated by combining a plurality of distortion-corrected division region images (D). Regarding each pixel of the distortion-corrected image (D), a gain (Gp) is determined according to scaling ratios (MR) of a division region including the pixel and one or more division regions around the division region, high-frequency components (D) of the pixel are multiplied by the gain (Gp), and the product is added to a pixel value of the pixel of the distortion-corrected image (D). This makes it possible to lessen the difference in the sense of resolution among the division regions of the distortion-corrected image (D) and obtain an image having an excellent sense of resolution.
