Abstract
A method of measuring a distance by using a 3-dimensional (3D) depth sensor is provided. The method may include: measuring m number of frames using light modulated at a first frequency to determine a first tentative distance from a viewpoint to an object at the first frequency, m being a positive integer; measuring n number of frames using light modulated at a second frequency to determine a second tentative distance from the viewpoint to the object at the second frequency, n being a positive integer, a sum of m and n being four; and determining a resulting distance to the object based on the first distance and the second distance.
