COLOUR GAMUT COMPONENT ANALYSIS APPARATUS, METHOD OF ANALYZING COLOR GAMUT COMPONENT, AND COLOR CAMUT COMPONENT ANALYSIS PROGRAM

摘要

The present invention enables to make the user visually recognize the presence of a wide color gamut component and the ratio as easy to understand. [Solving Means] According to the present invention, histogram processing is performed on color components in a video signal, a wide color gamut component amount WC larger than a signal by a predetermined standard is calculated from the result of the histogram processing, and a graphic processed image G1A, G2A or G3A that shows the presence of a wide color gamut component in the video signal, or the ratio of the wide color gamut component amount WC to the video signal is generated and outputted. It can make the user visually and immediately recognize the presence of the wide color gamut component amount WC larger than the signal by the predetermined standard or the ratio. [Selected Drawing]
