Claim:
1. A method of processing a 3 dimensional (3D) image, which is processed by a digital device containing a light-receiving unit including a first sensing unit to sense a visible light and a second sensing unit to sense an infrared light and a light-emitting unit to emit the infrared light, comprising the steps of: switching by a control unit a resolution of the light-receiving unit from a first resolution to a second resolution which is lower than the first resolution, if the resolution of the light-receiving unit corresponds to the first resolution; sensing by the light-receiving unit the visible light and the infrared light from a subject; extracting by an image processing unit color image information from the visible light sensed by the first sensing unit of the light-receiving unit during a first time interval; extracting by the image processing unit depth image information from the infrared tight sensed by the second sensing unit of the light-receiving unit during a second time interval; determining by the control unit whether extraction of both the color image information and the depth image information for the subject is completed; and if the extraction of both the color image information and the depth image information for the subject is completed, implementing by a 3D image implementing unit a 3D image of the subject based on the extracted color image information and the depth image information, wherein when the resolution of the light-receiving unit is switched from the first resolution to the second resolution which is lower than the first resolution, a time interval between an RGB frame and an IR frame is increased, and the control unit controls the light-emitting unit so that the time of turning on the infrared light is increased as much as the increased time interval between the RGB frame and the IR frame.
