Color image

(重定向自Colour image)
 Separate R, G, and B image layers

A (digital) color image is a digital image that includes color information for each pixel.

For visually acceptable results, it is necessary (and almost sufficient) to provide three samples (color channels) for each pixel, which are interpreted as coordinates in some color space. The RGB color space is commonly used in computer displays, but other spaces such as YCbCr, HSV, and are often used in other contexts.A color image has three values per pixel and they measure the intensity and chrominance of light. The actual information stored in the digital image data is the brightness information in each spectral band.
