Claim One:
1. A computer-implemented method for recognizing a hand motion by a hand motion recognizing apparatus, the method comprising: obtaining an image with first resolution including a hand; obtaining an image with second resolution including the hand; mapping, by a processor, the image with the first resolution and the image with the second resolution; obtaining a hand position from the image with the first resolution; extracting, by the processor, a hand region corresponding to the hand position from the image with the second resolution mapped to the image with the first resolution; and estimating, by the processor, a hand motion from the hand region, wherein the image with the first resolution and the image with the second resolution are obtained from a single image sensor, wherein the image with the first resolution is a depth image and the image with the second resolution is an infrared (IR) image, wherein the obtaining of the image with the first resolution comprises creating the image with the first resolution by projecting IR light to an object and measuring a time duration in which the IR light is returned after being reflected from the object, and wherein the obtaining of the image with the second resolution comprises creating the image with the second resolution by using the IR light itself which is reflected from the object as it is.
