  • Patent number: 8520022
    Abstract: Display functions in an electronic device may comprise combining runtime color adjustments with brightness adjustments triggered by ambient light detection. Light sensors may be utilized to detect ambient lighting conditions, which may cause adjustment of brightness level applicable to a display (or screen) of the electronic device. The adjustment of brightness level may then be combined with adjustment of contrast level that may also be applicable to display functions. In this regard, a particular contrast level may be selected based on the detected ambient lighting conditions—e.g., by mapping various contrast levels to preconfigured ambient lighting levels. The contrast adjustment may comprise adjusting colors and/or sharpness. Using contrast adjustments, in conjunction with the brightness adjustments, may allow for achieving the same levels of readability with less brightness, and/or for increased readability with the same brightness.

  • Patent number: 8436921
    Abstract: A picture signal processing system includes a playback apparatus and a display apparatus connected via first and second communication units. The playback apparatus receives a video signal made up of source data generated by moving giant image data in a constant direction at a constant speed, wherein the giant image data has a number of pixels far greater than the number of pixels in a display region. The playback apparatus reads source data speed information stored in the video signal header, and transmits the video signal and the speed information to the display apparatus. The display apparatus references a table to determine how to process the video signal on the basis of the speed information, processes the video signal, and then displays the processed video signal.
