PICTURE QUALITY CONTROL APPARATUS AND METHOD FOR REGION OF INTEREST BY USING DEPTH INFORMATION

摘要

PURPOSE: A region of interest image quality control device and a control method thereof using distance information are provided to apply a relatively large quantized step size to an object far from a camera and apply a relatively small quantized step size to an object relatively close to the camera. CONSTITUTION: A distance image control unit (130) compares the resolution of a distance image calculated by a distance image calculation unit (120) with the resolution of a color image. An image quality control unit (150) performs image quality control regarding a distance with respect to each object grouped by an object extraction unit (140). A distance image adjustment unit zooms in or out regarding the size of the distance image resolution based on the resolution of a color image.
