Colour Space

Colour space can also be known as colour model and sometimes colour system. It is basically the range of colours that cameras pick up on, printers print and monitors display. Adobe RBG was created by Adobe in 1998 to encompass most colours available with CMYK printers, but using RGB colour space on such as monitors.

Hue is the colour or shade that something is, whereas saturation is the intensity of that hue. Greyscale colour space is when an image is made up of pixels containing black and white hues (light shades are transformed into hues of white, darker shades are transformed into hues of black) with various saturations.

A pipeline is the set of components used between an image source and the image reader.  YUV is the usual colour space for pipelines or colour images. YUV contains luminance and chrominance - Y (one luma) and UV (two chrominance components). It defines colour spaces, representing the brightness and colours in an image.
