NTSC gamut: the sum of colors under the NTSC standard.
First, a color gamut is a way to encode a color, and it also refers to the sum of colors that a technology system can produce. In computer graphics processing, a color gamut is a complete subset of colors. The most common use of a color subset is to accurately represent a given situation. For example, a given color space or the color range of an output device.
Second, NTSC is National Television Standards Committee (United States) state television Standards Committee. It is responsible for developing a set of United States standard television broadcast transmission and reception protocols. The NTSC standard has not changed much since they were created except for the addition of new parameters to the color signal. It defines the frame speed as a 30/s or 60 scan field, and is interlaced on the TV. 29.97 frames per second (simplified to 30 frames), TV scan line for 525 lines, even before the field, the odd field, the standard digital NTSC TV standard resolution of 720*486, 24 bits of color bit depth (24 bit depth can represent about 16.7 million different colors.) Because the eyes of ordinary people can only differentiate about 1200~1400 different color shades and shades, so 24-bit color is also called "photo" color or True color. Typically, 24-bit color channels are assigned 8-digit data, which means: red, green, blue, each of these three primary colors can have 256 variations. ), the screen has a height ratio of 4:3.
