  • Patent number: 7430337
    Abstract: Ringing artifacts are removed from a quantized image by an image de-ringing filter that includes a determination unit, an adaptive filter and a nonlinear low-pass filter. The determination unit determines whether each selected pixel of a first set of selected pixels of an image contains a ringing artifact based on, for example, gray-level values of selected pixels within a determination kernel of pixels relating to the selected pixel. The adaptive filter generates a filtered gray-level value for each pixel determined by the determination unit to contain a ringing artifact based on, for example, gray-level values of selected pixels within a filtering kernel of pixels relating to the pixel. The nonlinear low-pass filter generates a low-pass-filtered gray-level value for each selected pixel of a second set of selected pixels of the image.

  • Publication number: 20080231581
    Abstract: A liquid crystal display apparatus enables image display with optimum quality corresponding to the genre of an image to be displayed. The liquid crystal display apparatus controls the emission luminance of a backlight according to the APL of an image signal measured at an APL measuring portion 14. Upon emission luminance control, the display apparatus sets the follow performance of a change of the backlight emission luminance in following a change in a characteristic quantity of the image signal according to a genre so that the display image can be viewed without an odd feeling. Specifically, the APL of the image signal measured at the APL measuring portion 14 is put into a filter 15, and the rate of a change in the APL on the time axis is controlled through weighted averaging to control the follow performance of the emission luminance control on the backlight.
