SUBCODE
MAIN
PIIP
EXAMPLE:
(FRZ+MAIN 1) - Freeze the main image.
(GAM) GAMMA CORRECTION
CONTROL GROUP:
DESCRIPTION
The Gamma Correction control is used to correct ambient conditions affecting the display. The Gamma control
affects the shape of the curve determining what grey shades are displayed for a given amount of signal Input
between minimum (black) and maximum (white). This is done by performing a linear transform from the user
selected gamma channel setting. The normal point is 0, meaning the selected gamma table is used unaltered. If
there is a lot of ambient light, the image can become washed out, making it difficult or impossible to see details in
dark areas. Increasing the gamma correction setting can compensate for this by transforming the curve towards a
gamma of 1.0. Decreasing the control shall transform the gamma towards a gamma of 3.0.
