Method and apparatus for setting the color balance of a color display device

Apparatus for setting the color point of a color display device, the apparatus comprising a video signal generator for generating an image on the color display device and a color analyzer for measuring the chromaticity of the image to produce digital coordinates corresponding to the color point of the image on a chromaticity reference chart, characterized in that the apparatus further comprises a computer system connected to the color analyzer, the computer system comprising:

• interface means for reading the digital coordinates from the color analyzer;
• means for generating a graphical representation of said chromaticity reference chart;
• color point target means for specifying a point on said reference chart representing a color point target;
• display means for displaying said graphical representation of said chromaticity reference chart, a cursor at a point corresponding to the coordinates within said graphical representation of the chromaticity reference chart and said color point target;
• and
• processor means responsive to said interface means for moving the cursor within the graphical representation in response to a change in the coordinates read from the color analyzer.
