Rectangular gamut display
View Patent ↗A system for providing an easily usable composite legality and component gamut display translates a video input signal into a plurality of component and composite format signals. A user selects from the plurality of component and composite format signals a pair of signals for input to the y-axis and x-axis of a rectangular plot. The resulting rectangular plot includes every pixel within a video frame of the video input signal and, together with prescribed limits, is displayed to provide a visual indication of composite legality and/or component gamut.
1. A method of providing a rectangular gamut display comprising the steps of:
translating a video input signal into a plurality of component and composite format signals;
selecting from the plurality of component and composite format signals a first signal for input to a y-axis of the rectangular gamut display and a second signal for input to an x-axis of the rectangular gamut display to form a graphic plot that includes each pixel within a video frame of the video input signal; and
displaying the graphic plot together with prescribed limits to visually indicate whether any pixels are outside the prescribed limits.
2. The method as recited in claim 1 further comprising the step of:
describing a shape area within the graphic plot; and
repeating the selecting and displaying steps for the pixels within the shape area to produce a secondary graphic plot.
