  • Image processing apparatus
    Patent number: 8797427
    Abstract: An image processing apparatus includes, a color correction unit performing color correction on RGB signals to generate color-corrected RGB signals; a YC conversion unit converting the color-corrected RGB signals into a first luminance signal and a color-difference signal; a Y conversion unit generating a second luminance signal based on the RGB signals; an edge combination unit combining the first luminance signal with the second luminance signal; an edge adjustment unit obtaining an edge-adjusted signal based on a result of the combining by the edge combination unit; and an adder adding the first luminance signal to the edge-adjusted signal.
    Type: Grant

  • Noise reduction device and noise reduction method
    Patent number: 8705883
    Abstract: A noise reduction device includes a line buffer that stores a blend value obtained by blending a pixel value stored in the line buffer with a processing target pixel value at a given ratio by an amount of one line of an image, and a selector that selects the blend value when a difference between the blend value in the line buffer and the target pixel value is less than a threshold, and that selects the target pixel value when the difference is greater than or equal to the threshold.
