NurPhoto via Getty Images, FILEWhen showing off vacation photos to a friend, how many times have you uttered the phrase"You really had to be there" or"It looked much better in person"? No matter how much smartphone cameras advance, digital photos often pale in comparison to the vibrant images before our eyes.
Now, researchers from China have developed a new approach to digitizing color that could help improve the realism of cameras, displays and LED lighting. Instead of using RGB combinations to form a color space, the new set of algorithms produces colors based on standards set by the International Commission on Illumination , a device-independent system that takes into account how humans perceive colors.
"Imagine that one day you are using a CIE-based digital camera to record a wonderful scene in a CIE-format image file. You will also be able to transfer the digital file to a computer with a CIE-based display to show your friends the happy time," said study author Jiyong Wang of Westlake University."In this way, the scenes in our eyes can be stored and reproduced to a maximum extent of reality.
They chose to work with the CIE color space because it is device-independent, meaning that the same values should be perceived as the same color by a standard observer even if different devices are used. Validation experiments to mimic lighting, display and sensing applications demonstrated that chromaticity, a measure of colorfulness separate from brightness, could be controlled with much more precision than the human eye can detect.
