Title:
METHOD AND APPARATUS FOR DYNAMIC IMAGE CONTENT MANIPULATION
Document Type and Number:
WIPO Patent Application WO/2014/140122
Kind Code:
A3
Abstract:
For dynamic image content manipulation, a target area key signal KA defines a target area of a first program signal PGM1 which is to be modified. A difference key signal KD is generated as a combination of the target area key signal KA and a graphics key signal KG which defines coverage over a clean feed image signal CF by a graphics fill signal FG to give the first program signal PGM1. A difference fill signal FD is derived according to image differences between the first program signal PGM1 and the clean feed image signal CF. In one example, at least one modified program signal M-PGM is produced by combining the first program signal PGM1 with an alternate content fill signal FA according to the difference key signal KD and the difference fill signal FD.
