Claim:
1. A method of recognizing motion of an object, the method comprising: periodically obtaining depth data of a first resolution and two-dimensional data of a second resolution with respect to a scene using an image capturing device, wherein the second resolution is higher than the first resolution; determining a motion tracking region within the scene by recognizing a target object within the scene based on the depth data, such that the motion tracking region within the scene corresponds to a portion of a frame and the portion includes the target object; periodically obtaining tracking region data of the second resolution corresponding to the motion tracking region within the scene; and analyzing the motion of the target object based solely on the tracking region data, wherein periodically obtaining the depth data and the two-dimensional data includes: periodically providing raw data corresponding to the frame using time-of-flight (TOF) depth pixels, the TOF depth pixels operating in response to a plurality of demodulation signals having different phases from each other; and calculating the depth data of the first resolution and the two-dimensional data of the second resolution based on the raw data.
