AdjustColor

DESCRIPTION

This module corrects an RGB image to be NTSC/PAL compliant in color space. It does it by reducing the saturation.

INPUTS

Port: Input
Type: Lattice
Constraints: 2-D.
3-vector.
byte.
uniform.
Input image for color correction

WIDGETS

Port: gamma
Type: Dial
Gamma of the monitor

Port: video
Type: Radio Box
Menu Item: NTSC
Menu Item: PAL
NTSC or PAL button

Port: chrominance
Type: Slider
The limit of the overall Chromanance amplitude in IRE units. A good value is 50.

Port: composite
Type: Slider
The maximum amplitude of the composite signal in IRE units. 120 is the limit for NTSC broadcasting.

OUTPUTS
