Abstract
A digital camera shoots a document plural times from different directions to obtain a plurality of images. An image processing device included in the digital camera corrects the keystone distortion of each image to generate an image which seems as if the document were shot from in front of it. The image processing device synthesizes the images by addition-averaging the pixel values of each pixel in the plurality of corrected images. Even if captured images are illuminated by glare from a light because a document made of glossy paper is shot, the influence of the glare is reduced by addition-averaging the pixel values of each pixel in the plurality of images.
