Epson uses new Colour Light Output measurement for its projectors

Epson has announced that it is to start using the Colour Light Output (CLO) measurement on its projectors.

Developed by Lumita at the end of 2007, CLO works on the same principle as the white light brightness measurement.

How is Colour Light Output measured?

Three RGB colour patterns are divided into nine separate areas. The luminance of the nine areas is then measured for each pattern, and an average value taken for each of the patterns. Finally, the Colour Light Output is calculated by adding the average values of the three patterns.

So expect to see a new measurement listed in Epson's future video projector specs.
