Apple recently filed for a patent called “Dynamic Backlight Adaptation for Black Bars with Subtitles” that may be used to provide improved picture quality in its rumored HDTV. Apple explained in the patent application that the black bars above and below video on widescreen televisions can make it tough for a television panel to display blacks properly. ”These non-picture portions complicate the analysis of the brightness of the video images, and therefore can create problems when determining the trade-off between the brightness of the video signals and the intensity setting of the light source,” Apple said in the patent. “Moreover, these non-picture portions can also produce visual artifacts, which can degrade the overall user experience.” Apple’s solution would be to dynamically change the backlighting.

“The system determines the intensity setting of the light source on an image-by-image basis for the sequence of video images, where the intensity of the given video image is based on the brightness setting and/or brightness information contained in the video signals associated with the given image,” Apple explained. ”Then, the system synchronizes the intensity of the setting of the light source with the current video image to be displayed.”
