IMAGE SIGNAL PROCESSING SYSTEM FOR SUGGESTING STANDARDIZED GAMUT METADATA, CAPABLE OF REPRODUCING COLOR IN EACH SINK DEVICE

摘要

PURPOSE: An image signal processing system and a method thereof are provided to convert a video signal of a specific source device to fit the characteristic of each device, thereby improving color reproduction.;CONSTITUTION: A source device(500) transmits a gamut metadata packet related to a video image. A HDMI(High Definition Multimedia Interface) sync unit(512) decodes an input data. The HDMI sync unit processes a control data of the source device. A video processing unit(514) processes the processed video data to fit a panel(517) and a requirement of a user. A xvYCC processing unit(515) executes gamut mapping in one part among xvYCC block by the measurement data of a panel.;COPYRIGHT KIPO 2011
