is a one-glass dialyte lens, enabling color correction at a virtual image plane. The overall viewer experience is enhanced because the display is uniform and colors are accurate. An investigation of the chromatic effects in refracting optical systems. Drag the UI widgets to the UI Camera (make sure they are children of the camera) Open up the UI widgets and delete everything except the 'UI Color Picker' Fully expand the UI Color Picker and put everything on the UI layer Now that we have our slider visible, it is time to tweak the appearance. When these correction coefficients are applied to an incoming video signal the result is a screen with uniform brightness and color performance, with a specified color gamut that allows predictable color representation. The Colorlite Color Vision Diagnostic and Correction System is for eye care professionals who are interested in helping color deficient people in their practice. Based on this measurement, VisionCAL application software then computes optimal correction coefficients for each LED and LED screen pixel. VisionCAL uses a ProMetric® Imaging Colorimeter to measure the color and brightness of every LED in an LED module or screen. The most cost-effective and adaptable method of achieving color and brightness uniformity for LED screens takes advantage of the science of LEDs and LED screen pixels: LED brightness can be reliably regulated by adjusting the power supplied to an individual LED, and the perceived color of an LED pixel can be adjusted by color mixing. VisionCAL optimizes LED screen appearance The system is designed to be flexible enough to address LED module correction needs in a controlled factory environment and to also perform in-field correction of the large LED video screens used in stadiums, in arenas, for outdoor advertising, or for large indoor displays. VisionCAL is a patented, turnkey solution for LED screen manufacturers and installers that can be used to dramatically improve color and brightness uniformity in many LED displays. Advanced system for automated color and brightness correction of LED modules and screens
