represented as separate chrominance and luminance. Same as “chroma”.

The fraction of a motion picture frame image that is intended to be viewed by the

audience. The clean aperture is subjectively free of edge artifacts and lies within the

screen area framed by curtains in a cinema. Aspect ratio is often referenced to the

clean aperture.

The range of colors allowed in a specific system, as defined within a triangular area

located on the CIE color locus diagram whose corners are the three primaries of the

system. Same as color space.

A change in the tint of a white field across an image.

using the Kelvin (degrees K) temperature scale. Higher temperatures output more

light.

See YCbCr or YPbPr.

less than 180

create the distribution master and for reformatting for NTSC, HDTV, DVD, etc., and
