Convert NTSC values to RGB color space
Syntax
Description
rgbmap = ntsc2rgb(yiqmap) converts the m-by-3 NTSC (television) color values in yiqmap to RGB color space. If yiqmap is m-by-3 and contains the NTSC luminance (Y) and chrominance (I and Q) color components as columns, then rgbmap is an m-by-3 matrix that contains the red, green, and blue values equivalent to those colors. Both rgbmap and yiqmap contain intensities in the range 0 to 1.0. The intensity 0 corresponds to the absence of the component, while the intensity 1.0 corresponds to full saturation of the component.
RGB = ntsc2rgb(YIQ) converts the NTSC image YIQ to the equivalent truecolor image RGB.
ntsc2rgb computes the RGB values from the NTSC components using
Class Support
The input image or colormap must be of class double. The output is of class double.
