Color Spectrum sensor was launched by LG on the LG G4.
What does a 'color spectrum sensor' do, and why is it better than a regular sensor? LG explaind the benefits of the new technology at its official unveiling event for the handset:
"The advanced camera in the LG G4 is complemented by Color Spectrum Sensor (CSS), the first feature of its kind to find its way into a smartphone. CSS improves color accuracy by precisely reading the RGB values of the ambient light in a scene, as well as the infrared light reflected from objects. CSS uses this information to adjust the camera’s white balance and flash color to create images that are as close to what one would see with the naked eye. With Color Spectrum Sensor, no longer will reds appear as bright orange or whites as dull yellow."
