摘要： A method and apparatus for expanding bit resolution using local information of an image receives an input image. First, second and third threshold value used to enhance bit resolution, to detect a texture and to detect a pattern, respectively, are determined considering global information of the input image. A texture existing in a mask region composed of surrounding pixels within a predetermined range around a current pixel is determined using the second threshold value. A regularly repeated pattern existing in the mask region is determined using the third threshold value if no texture exists in the mask region. The first threshold value is decreased if a texture or pattern exists in the mask region. Values of mask region pixels are adjusted depending on the first threshold value, and bit resolution of the current pixel value is enhanced using a resultant value obtained by filtering the adjusted pixel values.

摘要： A method is provided for reducing occurrence of color fringe errors occurred at the time of carrying out a color filter interpolation and reducing degradation of an image quality. Interpolation of a G channel value in a pixel of the color filter having only R or B channel values is carried out such that a similarity measured between channels based on interpolation results in horizontal and vertical directions are measured, and the G channel interpolation is carried out in a direction where the measured similarity becomes the maximized. However, when the reliability of the measured similarity becomes poor, a final G channel interpolation is carried out using a weighted average value using similarity information of each direction and interpolation results of the horizontal and vertical directions.
