Phase One Trichomatic: Marketing vs Technology

Luminous Landscape publishes an article by Doug Peterson on the recently announced Phase One Trichromatic image sensor explaining the science behind it. There is a striking difference between the marketing presentation and what has been really done.

However, the real color response looks quite different:

The main color filter improvements developed together with Sony are:

The amount of overlap between the red, green, and blue spectral responses is decreased and is steeper
The improved “tail clipping” in the cleans color contamination
Near-UV cut
Colors balanced with respect to how much light pixels see
