Xe8472 is a first-of-its-kind technology that simulates the human visual system. Xe847 simulates the so called color-constancy of the human visual system: up to a certain degree, the human eye perceives the color of objects as constant even if the ambient light or the illuminant changes. Whether illuminated by direct sunlight or fluorescent lighting, human skin always looks natural. Xe847 was developed on the basis of physiological processes in the visual cortex of the brain as well as some higher psychological effects.- w7 |. O! A8 @

The Human Visual System: C. E1 e0 a* y$ A. L0 i& c
The visual perception of humans is a highly complex process. What we ’see‘ is not a representation of technical optical data, it’s an interpretation of this data by the human brain.

Direct warm sunlight. The human skin and all objects also reflect the ambient light from the blue sky. The camera sees and records this. Even the latest generation of professional Cameras.. R8 r' F5 \- ^- Q
The human brain however will compensate for this. What we (humans) actually experience is the same skin color that we would under varying lighting conditions. (within some limits)

Xe8472 deals with a topic called „Color Constancy“ which both NASA and MIT researched for decades with no practical outcome to date. NASA Langley Research Center’s comments on the topic:

It is no challenge to invent algorithms that correct color shifts, the real challenge is to know if there is a visible color shift at all and to simulate how the human eye-brain would actually perceive it.

From old FAQ
! r4 d0 Y9 I; W% {# ^$ sQ: Looks like one of those fix-0-matic or one-click-enhancements?
9 ?3 Z" m2 e9 N( |, ?+ G; W" zA: Xe847 is NOT a one-click-enhancement for bad pictures.* i) k* ^- E# g
It was specially designed to be used with unchanged image-data coming from a digital-camera or video-camera, not too much under- or overexposed. Look at it as if it was built into the camera in addition to the automatic exposure control. It will not remove extreme artificial colorshifts like that coming from old faded photos, or completely colored ambient light. It will not correct for extremely under or overerexposed Photos. It does what the human eye/brain does too. It filters a photo in such a way that it looks like you remember it.
