Description
本出願は、参照することによりそのすべてがここに含まれる2006年1月9日に出願された米国仮出願第60/757,372号“Illumination and Color Compensation System for Multi−view Video Coding”の利益を主張する。さらに、本出願は、参照することによりそのすべてがここに含まれる2006年1月9日に出願された米国仮出願第60/757,289号“Multi−View Video Coding System”の利益を主張する。さらに、本出願は、参照することによりそのすべてがここに含まれる共願出願“Methods and Apparatus for Multi−View Video Coding”(代理人整理番号PU060004)に関する。
本発明は、一般にビデオ符号化及び復号化に関し、より詳細には、MVC(Multi−view Video Coding)のための照度補償及びカラー補償のための方法及び装置に関する。カラー補償は、少なくとも1つのカラーコンポーネントに適用されるかもしれない。
MVCシーケンスは、異なるビューポイントから同一シーンをキャプチャする2以上のビデオシーケンスのセットである。MVCは、フリービューポイント及び3Dビデオアプリケーション、ホームエンターテイメント、サーベイランスなどを含む広範なアプリケーションを提供する主要な技術である。これらのマルチビューアプリケーションでは、極めて大量のビデオデータをしばしば伴う。
本発明は、MVCの照度補償及びカラー補償のための方法及び装置に関する。カラー補償が、少なくとも1つのカラーコンポーネントに適用されるかもしれない。
