I’m currently working on another improvement for the Blu-ray Benchmark that I run for Secrets of Home Theater and High Fidelity.  Right now we give people an overall DeltaE value, using both 1976 and 1994 formulas, for YCbCr and RGB components as an overall average.  Someone requested that I also give the error in Hue, Saturation, and Lightness percentages.

Doing this breaks down the error from a single number to one that indicates what component of the color is causing the issue.  Some people are more sensitive to certain errors than others, so this can provide some more detail for users.  At the same time, I might start to provide graphs showing the dE, and HSL% errors across the whole range of output values.  This will let you know if the issue is with shadows, mid-tones, highlights, or the whole spectrum.

Hopefully this will be done before any more Blu-ray reviews run, but since it needs to be coded I’m not sure that will happen.  Any other requests for data that people would like to see about Blu-ray players can be posted here and I’ll try to address them as quickly as I can.

Here’s a preview of what the data might look like, though it is only a first pass right now.  It has both DeltaE values, as well as Hue, Saturation, and Level Error Percentages.
