  • Patent number: 5781663
    Abstract: An image recognition apparatus recognizes an input locus as a command, a figure and a character, respectively in gesture recognition mode, figure recognition mode and character recognition mode. Regarding each recognized result, similarity between the input image and the recognized shape is obtained. The similarities are compared with each other, and if the difference between the similarities is less than a predetermined value, the recognized results are displayed for selection by an operator. Then, selected one of the displayed shapes is determined as the final recognition result. This enables correct locus input even if there is a possibility that the locus is recognized, in different recognition modes, as similar shapes of different functions.

  • Patent number: 5754686
    Abstract: In the present invention, an input handwritten character pattern is subjected to character recognition processing, and a recognition reliability of the character as a standard characteristic feature pattern is determined from the recognition result. If the recognition reliability is low, a warning is issued. In response to the warning, a user or operator can decide whether the character pattern should be registered in the user dictionary (106). If it is decided that the character pattern should be registered in the user dictionary, the character pattern is stored in the user dictionary with the information representing that the character pattern has low recognition reliability. When character patterns registered in the user dictionary are displayed on a screen, these characters are displayed in such a manner that it is possible to distinguish characters having low recognition reliability from characters having high recognition reliability.
