LG Shows Enhanced Dolby Vision Feature That Adjusts for Ambient Room Light

Dolby Vision IQ debuted at CES, with LG and Panasonic introducing the HDR enhancement technology that compensates for a room’s varying ambient light. Dolby described the feature as “intelligently optimizing picture quality experiences for viewers in any room at every moment, all without consumers picking up their remote.” Gregg Lee, LG senior product training manager, told us on a Tuesday booth walk-through that the feature gives users more control over Dolby Vision HDR, which they previously were unable to adjust. “A lot of times, the TV is in a unique environment -- maybe it’s lighter at one time of day and darker at another.” Dolby Vision IQ is able to look at the environment and compensate for the individual set in real time, he said, while standard Dolby Vision HDR is about matching TV brightness to the content. Dolby said Vision IQ uses Dolby Vision dynamic metadata and the ambient light sensors inside the TV to detect how bright or dark a room is, intelligently displaying every detail of the content so it looks its best. It can also inform the TV what is being watched so when a consumer switches channels, the set will modify its settings to ensure images are displayed as they should be seen. “Without Dolby Vision metadata, TVs are guessing rather than making intelligent scene-by-scene optimizations,” it said. Dolby Vision IQ will be included in LG sets powered by the TV maker's latest Alpha 9 series processors, Lee said.
