    Abstract: Extracting and processing video content encoded in a rendered color space to be emulated by an ambient light source, comprising extracting dominant color information from a video signal and transforming the color information through unrendered color space using tristimulus primary matrices to form a second rendered color space for ambient distribution. Steps include quantizing the rendered color space to form an assigned color distribution, such as by reducing possible color states, or binning to form superpixels; and selecting a dominant color using a mode, mean, median, or weighted average of pixel chromaticities. A color of interest can be further analyzed to produce a true dominant color, and past video frames can guide selection of dominant colors in future frames.

    Abstract: The invention relates to methods, devices and computer program codes for enabling simple seamless switch over between content related media streams, selecting a switching scheme and performing simplified switch over between such streams, as well as a set of media signals. The media streams (TS1, TS2, TSN) have access units (AU1, AU2, AU3), the lengths of which are made equal by adding filling packets (N). By doing this, overhead data (O1, O2, ON) related to the streams can also be made almost identical. This fact is then used for fast determination of switch over method and simplified seamless switch over between different media streams.

That is, the sidewalls reflect a first group of light, which has relatively higher luminance by passing through a short axis of liquid crystal, towards a second group of light having a relatively lower luminance by passing through a long axis of liquid crystal. Accordingly, the viewing angle of the liquid crystal display device is expanded and the gray scale inversion is reduced.

    Abstract: The present invention provides a color filter that makes a liquid crystal display satisfactorily reproduce halftone color by effectively reducing color shift that occurs when the color on the liquid crystal display is changed stepwise from white to black, and a liquid crystal display comprising the color filter. A color filter 10 comprises red, green, and blue color patterns 10R, 10G, 10B corresponding to the display areas that the respective pixels in a liquid crystal driving cell 20 form. In the color filter 10, the contrasts of the red, green, and blue color patterns 10R, 10G, 10B (the individual contrasts of the color patterns) are preferably in the following relationship. Specifically, it is preferred that the contrast CR of the red color pattern 10R, the contrast CG of the green color pattern 10G, and the contrast CB of the blue color pattern 10B fulfill the relationship CR<CG<CB, as well as the relationship CR:CG=1.0:1.2 to 1.0:2.5, and CR:CB=1.0:1.5 to 1.0:4.5. The CR is preferably 700 or more.

  • Publication number: 20080094555
    Abstract: Two phase retardation compensation films with upper and lower slow axes being orthogonal to each other are used to clip a liquid crystal (LC) cell in a transflective liquid crystal display. In an orthogonal polarizer system, the axial difference between the slow axes of the retardation films and the LC molecules director in the LC cell is used to obtain the most suitable phase difference. The ON and OFF of the LC voltage are used to achieve the display function at the darkest state and the brightest state, so as to achieve a transmissive optical mode having low dispersion, wide viewing angle, and ultra-low dark state, without damaging the reflective mode.
