This enlarged original image 273 which would be present within enlarged image 271 might then be printed by a printer. Four-sided borderless copying is possible.

Abstract: A method is provided to automatically arrange scanned images so they can be stitched into a composite image. Initially the scanned images are reduced to low resolution and a gradient filter is applied. One scanned image is selected as a possible first image in a stitching order. The possible first image is rotated to one angle and correlated with remaining scanned images rotated to two corresponding angles. Only four scanned images that best correlate with the possible first image and pass a threshold are saved as possible second images in the order. The steps are repeated for subsequent places in the order and for the possible first image at other angles. The method is repeated for other possible first images to form other orders. At the end, a path through one of the orders that produces the best sum of correlation values is set as the correct stitching order.

Abstract: An information-processing device for combining a plurality of pages including image data to printing image data printed on one sheet, and converting the combined pages to input image data for a image forming device is disclosed. When a multi-page print instruction is issued, a data generation unit in the information-processing device sets a maximum number N for combining the pages to one sheet, determines the size and the orientation of the sheet to be fed to an image forming point in the image forming device, and reserves a data storing region in an image buffer for producing the printing image data. The data generation unit produces the printing image data having the same orientation as that of the sheet fed in the image forming device when combining the page. Therefore, a process for rotating the printing image data itself is not necessary.

Abstract: A system controller 115 has a function of changing the position and the orientation of character data to be superimposed on the image data, in accordance with the operation of one of orientation keys. Specifically, when a downward key has been pushed, the character data is superimposed on a lower portion of the image data, not revolved and but oriented upward.

When an upward key has been pushed, the character data is revolved through 180 degrees, and is located along the upper edge of the image data, oriented downward. Further, when a leftward key has been pushed, the character data is revolved clockwise through 90 degrees, and is located along the left-hand edge of the image data, oriented rightward.

Abstract: A frame buffer stores X pixels per line and Y lines and is read using a burst of B pixels. The un-rotated image is rotated by 90 degrees for display by writing and reading pixels from a line buffer. The line buffer stores a block of B*Y pixels. The frame buffer is logically divided into X/B blocks that are B pixels wide. Blocks are read from the frame buffer from the bottom line to the top with a burst of B pixels per line. An offset locate pixels to read in the line buffer. The offset is B for the first block, and increases by a factor of B for each block read, but wraps around modulo B*Y?1. Pixels for a next block are written into the line buffer to locations vacated as pixels are read out. The increasing offset re-orders the pixels for the rotated display order.

Abstract: In methods, systems, and computer program products for locating a regularly configured object within a digital image, a plurality of primary rotated integral images of the digital image are computed. Each primary rotated integral image has a different in-plane rotation. A set of secondary rotated integral images are derived from each of the primary rotated integral images.
