  • Patent number: 8570609
    Abstract: An image processing device is provided including: an acquiring unit that acquires position data expressing a position of plural reference images provided on a reference medium; a scanning unit that scans the plural reference images; and a determination unit. The determination unit derives the sum of positional misalignment amounts of corresponding reference images, between the position of reference images expressed by image data obtained by the scanning unit, and the position of reference images expressed by position data acquired by the acquiring unit. The determination unit executes alignment of the reference images using a common correction coefficient predetermined so as to give the smallest sum of the positional misalignment amounts. Then the determination unit determines a dilation amount for image dilation on image data such that the dilation amount increases as the sum of the positional misalignment amounts increases.

  • Patent number: 8340467
    Abstract: A first movement control section sequentially moves a first image to multiple first positions. A first comparison section compares the moved first image with a second image. A target first position selection section selects a target first position based on the result of said comparison. After the target first position is selected, the second movement control section sequentially moves the first image to multiple second positions located in the periphery of the target first position. The second comparison section compares the moved first image with the second image. A target second position selection section selects a target second position based on the result of said comparison. A second position alignment execution section performs geometric transformation based on the difference between the position of the first image and the target second position and aligns the positions of the first and second images.

  • Patent number: 7738737
    Abstract: An image processing apparatus sequentially reduces a document, while changing the reduction factor step-by-step. Next, the image processing apparatus refers to the characters that constitute the document that has been reduced with the respective reduction factors, and specifies a reduction factor at which blank regions surrounded by line portions that express each character do not disappear. When an appropriate reduction factor is specified, the image processing apparatus specifies a resolution of the characters for that reduction factor, and converts the resolution of the document data to that specified resolution. Then, the image processing apparatus performs various processing for the document data whose resolution has been converted. Thus the resolution of document data is converted such that the document is reduced with a reduction factor suitable for computer processing.
