  • Patent number: 8175416
    Abstract: A pixel interpolation method includes the following steps. First, multiple first macroblocks and second macroblocks are generated according to pixel data of a first real pixel row and pixel data of a second real pixel row, respectively. Next, block matching is performed on the first and second macroblocks to find a minimum block difference and a detected direction of a target pixel belonging to a first interpolated pixel row. Thereafter, the target pixel of the first interpolated pixel row is generated by way of interpolation according to the pixel data of the first and second real pixel rows and the detected direction.

  • Publication number: 20100245383
    Abstract: A circuit for color space conversion and associated method compresses a portion of an xvYCC color space exceeding an sRGB color space into the sRGB color space via a simplified circuit design when a conversion from the xvYCC color space to the sRGB color space is performed, thereby improving visual effects. The circuit for color space conversion includes a conversion unit converting a pixel signal from the xvYCC color space to the sRGB color space. During the conversion, the conversion unit generates a pixel component on each dimension of the sRGB color space, and compresses the pixel component to output a compressed pixel component when a value of any pixel component is in a compression interval. The compressed pixel component does not exceed a defined range on a corresponding dimension of the sRGB color space.
