Abstract: <P>PROBLEM TO BE SOLVED: To simplify the correction of a distortion due to lens characteristics.  <P>SOLUTION: A digital camera 1 acquires a document image including a document 2 from a pickup image captured by imaging. The digital camera 1 compresses the document image and corrects a distortion due to lens characteristics on the compressed image. The distortion correction on the compressed image by the digital camera 1 reduces the computational complexity of distortion correction to simplify distortion correction. The digital camera 1 then acquires a binary edge image and a rectangle outlining the document 2 from the corrected compressed image to segment the document image, acquires the uncompressed original image and acquires a projective-transformed image associated by affine transformation. The digital camera 1 computes pixel positions in the original image by affine parameters from pixel positions in the projective-transformed image and computes pixel positions in the distortion-uncorrected image by the relational expression of the distortion correction performed on the compressed image.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
