DEPTH IMAGE GENERATING METHOD AND APPARATUS, AND DEPTH IMAGE PROCESSING METHOD AND APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a method for generating a depth image by use of light of different modulation frequencies and processing the generated depth image.SOLUTION: The depth image generation method includes steps of: irradiating an object with light of different modulation frequencies; detecting the light of the different modulation frequencies reflected from the object; and generating a depth image related to a distance to the object by use of the light of the different modulation frequencies.
