DEPTH REFINEMENT METHOD AND SYSTEM OF SPARSE DEPTH IMAGE IN MULTI-APERTURE CAMERA

摘要

Disclosed are a depth refinement system and a method for a sparse depth image in a multi-aperture camera. The method includes providing a sparse depth map generated based on an image obtained through each of a plurality of apertures included in the multi-aperture camera, wherein the sparse depth map includes depths of pixels included in the image, and performing a depth noise reduction (DNR) based on the sparse depth map.
