Abstract
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.
