    Abstract: PROBLEM TO BE SOLVED: To prevent a normalization result from being changed due to different character size or a different position by executing normalization by the adjust ment of parameters without especially changing a processing flow. SOLUTION: The image of a character and parameters for the character are applied to a scheduling program for executing practical enlargement/ reduction and seamless normalization is executed by the adjustment of the parameter without especially changing a processing flow. The parameters are the height of a virtual character frame, the height of the character, the width of the character, a distance from the virtual character frame up to the left end of the character, and a distance from the virtual character frame up to the upper end of the character. When a normalized output pattern is 24×16 (length X width), the aspect ratio of the character is the value of (character height)/(character width) and o- height, o- width, t- pad, and l- pad respectively indicate the practicaly height of a normalized character, the practical width of the normalized character, a distance from the upper frame of the virtual character frame up to the upper end of the normalized character, and a distance from the left frame of the virtual character frame up to the left end of the normalized character.

    Abstract: An area extraction method: extracts connected components having a predetermined size from an input image; divides the input image into small areas assuming that the small areas are mesh images having a predetermined size; determines a corresponding mesh image to which the extracted connected components belong; and extracts a specific area from the pixel's connection state of the corresponding mesh image to which it is determined the connected components belong.

    Abstract: PROBLEM TO BE SOLVED: To extract a specific area such as an address area fast with precision while evading a complicated integrating process in all pixels. SOLUTION: The image processor is equipped with a binarization part 12 which binarizes an image inputted by an image input device 10, a connecting pixel group detection part 14 which detects a connecting pixel group of the binarized pixels, a comparison part 16 which compares the size of the connecting pixel group with a predetermined threshold, a mesh image formation part 18 which forms mesh images by sectioning the mentioned input image into parts of a specific size, a corresponding mesh image detection part 19 which detects the corresponding mesh image to which a connecting pixel group judged by the comparison part 16 to be below the threshold value among the mesh images corresponds, a specific area extraction part 22 which extracts a specific area from the connection state of the detected corresponding mesh image, and an image recognition device 23 which recognizes the image positioned in the extracted specific area.

    Abstract: PURPOSE: To improve the error rate of a handwritten character recognizing process. CONSTITUTION: A method for recognizing handwritten character includes (a) steps A and B for giving time-sequentially arranged dynamic stroke information in response to a handwritten character input from a user, a step C for converting (b) the time-sequentially arranged dynamic stroke information and (c) time-sequentially arranged stroke information into static stroke information, (d) a step D1 for deciding a second list containing at least one possible character indicated by the static stroke information, (e) and steps E and F for combining first and second lists for giving a third uniformized list containing at least one element indicating the most possible character the time-sequentially arranged dynamic stroke information intends to indicate.

    Abstract: PURPOSE: To highly and certainly retrieve a color area by constituting a tree structural data reaching a root node by using a block including at least one picture element in a color picture area as a leaf node, and applying a color index based on a sensory color system to each node. CONSTITUTION: A color system converter 20 of a tree structural data preparing unit 2 converts RGB data 28 of each picture element of a memory 26 into HLS(hue, lightness, and saturation) data 30 of a sensory color system. A color class deciding device 22 divides the color space of the sensory color system into color classes, and decides color class data 32 of each picture element. A tree structural data converter 24 prepares a tree structure in which the least significant level is defined as a leaf node NB110 and the most significant level is defined as a root node NB by using, for example, a four divided-tree. A minimum block B110 corresponding to the leaf node NB110 is constituted of, for example, four picture elements, and the color index of the leave node NB110 is decided from the color class of each picture element. Then, the color index is applied to each node from the lower rank node to the upper rank node reaching the root node NB.
