Abstract
A device and a method for outputting video content for display on a display. At least one processor displays a first video content on the display, receives a second video content to display, obtains a first luminance value for the first video content, extracts a second luminance value from the second video content, adjusts a luminance of a frame of the second video content based on the first and second luminance values and outputs the frame of the second video content for display on the display. The video content can comprise frames and a luminance value can be equal to an average frame light level for the most recent L frames of the corresponding video content. In case a luminance value is unavailable, a Maximum Frame Average Light Levels of the first video content and the second video content can be used instead.
