Abstract
Disclosed herein are systems and methods for controlling luminance during video production and broadcast. An exemplary system includes a camera to capture video content in a first imaging range, a histogram calculator to evaluate luminance in each pixel in the captured video content, and to generate a luminance histogram for the captured video content, a user interface generator that generates a user interface displaying the video content overlaid with the luminance histogram and generates a user interface displaying a light intensity curve and adjustable parameters for converting the first range into a second range, a luminance controller to convert luminance of the video content into the second imaging range based on the light intensity curve, and a broadcast controller to encode the video content with the second imaging range into broadcast range for transmitting to one or more endpoint devices.
