    摘要: Character recognition method and apparatus according to the present invention comprises the partial pattern dictionary which classifies and registers partial patterns of characters to be recognized in accordance with direction data of strokes and the partial pattern composition dictionary which classifies and registers dictionary characters in accordance with the partial patterns. When a character image to be recognized is inputted, each stroke is converted into direction data. The partial pattern dictionary is searched by using the attained direction data and divides the character image to be recognized into a single or plurality of partial patterns. The partial pattern composition dictionary is searched by using the partial patterns attained in the above-described way. A dictionary character is thus attained as the result of recognition.

    摘要: A character recognition apparatus and method for recognizing an unknown character by comparing strokes of the input character with stroke information stored in a dictionary. Each stroke of the input character is classified into one of plural categories according to stroke direction. The classified input strokes are rearranged into groups of strokes having the same classification. The degree of analogy between rearranged input strokes and stroke information stored in the dictionary for each group of similarly classified stroke group is calculated based on stroke length, and a maximum analogous element for each input stroke according to the calculated degree of analogy is detected. The detected maximum analogous elements are summed together, and the character whose sum is maximum is output as the identity of the unknown input character.

    摘要: A pointed-position detecting apparatus where image output unit visually displays an image, and image input unit inputs the displayed visible image. The input visible image is stored into memory as an original image. The visible image is partially changed by using a manipulation device such as a laser pointer or a pointing rod, and the visible image with the partially-changed area is inputted from the image input unit. Controller extract the changed image area from the input visible image, and detects a pointed position based on the changed image area. Thus, the phenomenon where a user's action with respect to a displayed image is reflected as a change in the image is utilized to detect coordinates and motion at the image area as the object of change.

    摘要: An image information transmitting/receiving apparatus for time and cost-saving repetitive transmission. In facsimile communication, image data where further information is added to previously-transmitted image data is often received. In the present apparatus, the original image data is stored, and only difference data from the original image data is transmitted, thus the whole image can be reproduced at the receiving side, using the received difference data. Upon transmitting the difference image information, identification information identifying the difference image information is added to the difference information, and the entire image data to be received by the receiving side is stored. Upon receiving the difference image information, the received difference information is combined with the stored image data, and an image is reproduced based on the combined image data. Further, the image data used for image reproduction is stored as original image data for the next transmission. In this manner, once the original image data is stored, only difference data is sent at each subsequent transmission, thus reducing the amount of transmission data.
