Letterbox margin processing method for identifying letterbox margins of target frame according to frame packing type corresponding to 3D video input and related letterbox margin processing apparatus thereof

摘要

A letterbox margin processing method includes: receiving a three-dimensional (3D) video input; determining a frame packing type corresponding to the 3D video input; selecting a first image region from a target frame according to the determined frame packing type, wherein the target frame is derived from the 3D video input; and detecting letterbox margins within the first image region.
