    摘要： A device includes a display monitor configured to display on a screen of the display monitor at least one of a current image and a preceding image taken by an optical unit, a storage unit configured to store the preceding image, and a control unit configured to display a part of the preceding image on the screen when the current image is displayed on the screen, the displayed part of the preceding image indicating a positional relationship between the current image and the preceding image. The current image is taken when the displayed part of the preceding image substantially overlaps a corresponding portion of the current image such that the current image and the preceding image can be processed to form a panoramic image.

    摘要： A camera system includes a display monitor which displays an image of an object, taken by an optical unit, on a screen of the monitor. A reading unit reads a preceding image and a current image among a plurality of partially overlapping images, from a memory device, the preceding image and the current image containing a common element. A determining unit determines a positional relation between the preceding image and the current image based on a common pattern derived from the common element in the two adjacent images read by the reading unit. A displaying unit displays an image indicating a boundary of the preceding image on the screen of the monitor at a shifted position according to the positional relation determined by the determining unit, with the current image concurrently displayed on the screen of the monitor.

    摘要： A method and apparatus for detecting the skew angle of a document image. Skew angle determination is performed by the steps of determining a set of sampling points from an input document image and processing X and Y coordinates of the sampling points in order to calculate a regression coefficient of the sampling points. The skew angle of the document is determined using the regression coefficient. To evaluate a calculated skew angle which corresponds to the regression coefficient, a correlation coefficient is calculated and evaluated. As coordinates of sampling points are obtained for a plurality of sets of data corresponding to different ruled lines or lines of characters, a histogram may be used to determine the most probable skew angle.

    摘要： In a character recognition system, a method and apparatus for segmenting a document image into areas containing text and non-text. Document segmentation in the present invention is comprised generally of the steps of: providing a bit-mapped representation of the document image, extracting run lengths for each scanline from the bit-mapped representation of the document image; constructing rectangles from the run lengths; initially classifying each of the rectangles as either text or non-text; correcting for the skew in the rectangles; merging associated text into one or more text blocks; and logically ordering the text blocks.

    摘要： A method applicable to a character recognition system is disclosed which assigns direction codes to a number of boundary picture elements contained in a two-level character pattern. The direction of connectivity of a boundary picture element observed is fractionized to minimize the error due to the quantization of the direction. The direction codes are converted into those which correspond to connectivity directions which should be finally grasped. Such direction codes allow strokes to be extracted quite faithfully to the original character pattern.
