    摘要: In a data embedding apparatus a code calculating unit extracts a feature quantity from the image and calculates a code by using extracted feature quantity and a code embedding unit embeds calculated code into the image. An embedding determining unit that determines whether the code has been embedded normally into the image. If the embedding determining unit determines that the code has not been embedded normally into the image, an image-feature-quantity modifying unit modifies the extracted feature quantity. Finally, the code calculating unit extracts a new feature quantity from the image based on modified feature quantity, and recalculates a code by using the new feature quantity.

    摘要: An image data is inputted by using a device such as a document scanner. The input image data is scanned in a square block unit of M×N pixels, and blocks that satisfy specific conditions is detected based on the scanning process. In one example, a ratio of white pixels and black pixels falls within scanned blocks is used as the specific condition to detect those blocks. Then a region that neighbored by the other blocks is detected, and is extracted as a two-dimensional code region.

    摘要: The present invention relates to an image display control unit comprising a screen size information obtaining section, an image information obtaining section for obtaining information on vertical and horizontal sizes of an image, an arithmetic section for calculating an image magnification ratio so that at least one of the vertical and horizontal sizes of the image substantially conforms with at least one of vertical and horizontal display-possible sizes of a display screen, and a display control section for displaying the image at the magnification ratio calculated in the arithmetic section on the display screen. With this arrangement, in displaying an image on a display screen, the image can be displayed automatically at the optimal magnification ratio on the display screen. Accordingly, the wasteful use of the display screen is avoidable, and the image appears on the display screen in an easy-to-see condition.

    摘要: In a method of image compression in which vertical and horizontal white skipping are performed, data compression is performed in the regions containing black pixels other than the skipped regions. While vertical and horizontal white skipping being performed, in the other regions, regions are detected in which pixel values change in smooth fashion, such as the outlines of letters and encoding is performed using the pixel value of the leading column of the region, number of columns and amount of change of the pixel values. As a result, the compression factor of the image can be increased and a considerable contribution made to reduce the storage capacity for storage of data and reduce the time required for data transmission.
