Abstract
A digital camera (1) shoots a document plural times from different directions to obtain a plurality of images. An image processing device included in the digital camera (1) 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.
Claims11
An image capture apparatus for capturing an image of a subject, comprising:
- a correction unit (25) which corrects distortions of a plurality of captured images obtained by shooting the subject from different directions, to obtain distortion-corrected images;
- and
- an image synthesis unit (25) which performs a predetermined calculation for each pixel in the plurality of distortion-corrected images obtained by the correction unit (25) in order to reduce a change in a pixel value which is caused by glare from a light, and synthesizes an corrected image from the plurality of distortion-corrected images.
An image processing method for a captured image obtained by shooting a subject, comprising:
- a step of shooting the subject from different directions, and correcting distortions of a plurality of images obtained by the shooting to obtain a plurality of distortion-corrected images;
- and
- a step of performing a predetermined calculation for reducing a change in a pixel value caused by glare from a light, and synthesizing an corrected image from the plurality of distortion-corrected images.
A recording medium storing a program for controlling a computer to function as:
- a correction unit which shoots a subject from different directions, and corrects distortions of a plurality of images obtained by the shooting to obtain a plurality of distortion-corrected images;
- and
- an image synthesis unit which performs a predetermined calculation for reducing a change in a pixel value caused by glare from a light, and synthesizes an corrected image from the plurality of distortion-corrected images.
