APPARATUS AND METHOD FOR AUTOMATICALLY DETECTING OBJECT AND DEPTH INFORMATION OF IMAGE PHOTOGRAPHED BY IMAGE PICKUP DEVICE HAVING MULTIPLE COLOR FILTER APERTURE
Document Type and Number:
WIPO Patent Application WO/2013/125768
Kind Code:
A1
Abstract:
Disclosed are an apparatus and a method for automatically detecting an object and depth information of an image photographed by an image pickup device having a multiple color filter aperture. A background generating unit detects a motion from a current image frame from among a plurality of temporally sequential image frames photographed by an MCA camera, and generates a background image frame corresponding to the current image frame. An object detecting unit detects an object region contained in the current image frame based on a difference between each of a plurality of color channels of the current image frame and each of a plurality of color channels of the background image frame. According to the present invention, an object may be automatically detected by the background image frame being repeatedly updated, and an object may be detected separately for each color channel reflecting characteristics of the MCA camera to enable accurate estimation of the information on the object.
