Abstract

An example electronic device includes an image sensing tool to measure an average color balance value across a plurality of frames of a media stream. A processor verifies that the color balance value of the plurality of frames of the media stream is stable, and computes a selected color balance value of the media stream. An imaging device captures an image of a predetermined color calibration chart. The processor compares a color balance value of the image of the predetermined color calibration chart with a predefined color balance value, and validates the selected color balance value of the media stream to align with a selected region of the image.
