Image reader
First Claim
Patent Images
1. An image reader comprising:
- an image pickup unit for imaging a plurality of targeted adjacent portions at the same optical magnification rate to obtain a plurality of images;
a measuring unit for measuring a plurality of distances to a plurality of points respectively set on the plurality of targeted adjacent portions; and
a processing unit for perspectively transforming the plurality of images based on the plurality of distances to obtain a plurality of plane images, the processing unit for resizing the plurality of plane images in order for the plurality of plane images to have the same size.

Abstract
A CCD camera 10 picks up multiple adjacent targeted portions on a document 2, and to obtain distance information, a distance measurement unit 11 calculates the distances to the targeted portions of the document 2. Based on the distance information, a synthesization controller 16 prepares perspective information for the images, adjusts the sizes of the multiple obtained plane images so they correspond, and synthesizes the resultant plane images to form a single image.
