Patent number: 5805169Abstract: According to the invention, when an image is drawn, a check is made to see if the image is overwritten onto an image which has already been inputted and displayed, thereby switching. For this purpose, a color of the image to be drawn and a color of the image which has already been inputted are compared and the image of the color of a higher priority is displayed. According to the invention, there is no need to reset a display priority of the image by a manual operation of the operator in consideration of the priority of the image. When the image is inputted, the priority of the image can be simultaneously decided. As targets to which the invention is applied, there are an image inputted by a hand-writing, an image inputted by a scanner, a character pattern which is generated from a character generator, and the like.Type: GrantFiled: January 23, 1996Date of Patent: September 8, 1998Assignee: Canon Kabushiki KaishaInventors: Takashi Harada, Katsuhiko Sakaguchi, Shigeki Mori, Kazuhiro Matsubayashi, Tsunekazu Arai

Patent number: 5781663Abstract: 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.Type: GrantFiled: June 27, 1995Date of Patent: July 14, 1998Assignee: Canon Kabushiki KaishaInventors: Katsuhiko Sakaguchi, Tsunekazu Arai, Eiji Takasu, Hiroto Yoshii

Patent number: 5754686Abstract: 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.Type: GrantFiled: February 8, 1995Date of Patent: May 19, 1998Assignee: Canon Kabushiki KaishaInventors: Takashi Harada, Katsuhiko Sakaguchi, Shigeki Mori, Kazuhiro Matsubayashi, Tsunekazu Arai, Eiji Takasu, Hiroto Yoshii
