    摘要: A method of and apparatus for removing color noise are provided. The apparatus includes a first filtering unit, a subtracting unit, a second filtering unit, and an adding unit. The first filtering unit removes color noise from color data of a first channel among input interpolated color data and outputs filtered color data of the first channel. The subtracting unit calculates a difference between each of input color data of a second channel and a third channel among the input interpolated color data and the filtered color data of the first channel and outputs differential images. The second filtering unit selects an intermediate differential image among the output differential images and previously filtered differential images and outputs filtered differential images. The adding unit adds the filtered color data of the first channel and the filtered differential images and outputs filtered color data of the second channel and the third channel.

    摘要: A color interpolation method and apparatus for interpolating missing color signals for each pixel of an image sensor. The color interpolation method includes forming a difference image channel by subtracting an R or B color value from a G color value in pixels adjacent to a pixel to be interpolated, detecting the direction of an edge to which the pixel to be interpolated belongs and selecting adjacent pixels to be used for color interpolation. By calculating a weight value indicating the direction of the edge and providing the weight value to the adjacent pixels to be used for color interpolation, and using the difference image values of the adjacent pixels and the weight values, a color component missing in the pixel to be interpolated can be calculated.
