Abstract
A hand gesture recognizing device is provided which can correctly recognize hand gestures at high speed without requiring users to be equipped with tools. A gesture of a user is stereoscopically filmed by a photographing device,and then stored in an image storage device,A feature image extracting device,transforms colors of the stereoscopic image data read from the image storage device,in accordance with color transformation tables created by a color transformation table creating device,and disassembles and outputs the feature image of the user in corresponding channels. A spatial position calculating device,calculates spatial positions of feature parts of the user by utilizing parallax of the feature image outputted from the feature image extracting device,A region dividing device,defines the space around the user with spatial region codes. A hand gesture detecting device,detects how the hands of the user move in relation to the spatial region codes. A category is detected first on the basis of the detected hand gesture, and then a sign language word in that category is specified.
