METHOD FOR RECOGNIZING MOTION GESTURE COMMANDS
First Claim
1. A method comprising:
- defining a reference pattern;
receiving a frame from an image sensor that has captured a blurred image of an object;
identifying a shape of said blurred image included in said received frame;
comparing said identified shape of said blurred image with said reference pattern to determine whether or not said identified shape represents a gesture command; and
in response to a determination that said identified shape represents a gesture command, generating a corresponding command for controlling an operation of a computer.

Abstract
A computer capable of recognizing gesture commands is disclosed. Suppose that a user makes a gesture of swinging a hand from side to side in front of a camera associated with a computer. A camera module receives frames with shots of the gesture in order. The camera module calculates a gradation difference between corresponding pixels of each frame and a background image to generate a set of binarized differential images. The camera module then combines differential images to generate composite images. In response to a determination that any of the composite images matches a reference pattern, the camera module outputs a computer command. The computer command can be used to control the power state of the computer or start a specific application within the computer.

7. A method comprising:
-
defining a reference pattern with which a computer command is associated; setting an exposure time of an image sensor to capture a blurred image of a motion gesture; receiving, from said image sensor, a frame with said motion gesture shot therein; identifying a shape of said blurred image from said frame; determining whether or not said shape of said blurred image matches said reference pattern; and in response to a determination that said shape of said blurred image matches said reference pattern, sending a corresponding computer command to a computer. - View Dependent Claims (8, 9, 10)

11. A computer comprising:
-
a camera system; a reference image registering block for storing a reference pattern with which a command is associated; a blurred image processing block for identifying a shape of a blurred image of a moving object from a frame with the object shot therein; and a pattern recognition block for comparing said identified shape of said blurred image with said reference pattern; determining whether or not said shape of said blurred image matches said reference pattern; and generating, in response to a determination that said shape of said blurred image matches said reference pattern, a corresponding computer command. - View Dependent Claims (12, 13, 14)
