  • Patent number: 7167214
    Abstract: A signal processing unit in a liquid crystal display device, etc., includes a brightness component appearance frequency measuring unit that measures an appearance frequency of each brightness component in a video signal; a parameter outputting unit that outputs a distribution of each brightness component, as a parameter, based on the appearance frequency of each brightness component measured by the brightness component appearance frequency measuring unit; a changing signal outputting unit that alters an input signal recorded in a recording unit, by using the parameter, and that outputs the input signal as a changing signal; and a brightness component changing unit that changes a distribution of each brightness component, by using the changing signal, and that outputs the video signal in which the distribution of each brightness component is changed.

  • Publication number: 20050151424
    Abstract: In drive of loads such as cold-cathode tubes used for a back light device of a liquid crystal display, simplification of a composition required for an abnormality detection is given without spoiling detecting accuracy in the abnormality detection. Because of this, a driving device which drives a plurality of loads (ex. Cold-cathode tubes) in sequence includes a driving part which drives each of the loads in sequence by means of time division, and an abnormality detection part which detects abnormality of each of the loads at the time of the drive of each of the loads. The driving device detects abnormality of a load correspondingly to the sequential drive of each of the loads.

  • Publication number: 20050146532
    Abstract: A display apparatus is capable of switching the operation of a backlight for illuminating a liquid crystal panel, between a synchronization mode supporting a moving image for flashing the backlight in synchronism with switching of frames of the image and a non-synchronization mode supporting a static image for flashing the backlight in asynchronism. A moving image process detecting unit detects a moving image process for displaying a moving image on a display apparatus among the processes currently being executed. A screen state monitoring unit determines that the moving image screen detected by the moving image process detecting unit is maximized and positioned at the foreground, and instructs the display apparatus to switch the backlight into the synchronization mode.
