摘要

An image generation apparatus and a method of generating a color gamut information thereof, and an image playback apparatus and a method of detecting a color gamut information thereof are provided. The image generation apparatus includes a format converting unit converting a video stream from a first format into a second format; a color gamut information encoding unit encoding color gamut information in a section of the video stream ; and an output stream generating unit generating an output stream by combining the encoded information with the video stream. The image playback apparatus includes a stream inputting unit inputting a video stream encoded with color gamut information; a color gamut information decoding unit; a color gamut mapping unit mapping a color gamut of the video stream; and an image signal playback unit processing and playing back the video stream.
