    摘要: A bit-resolution-extension method is provided. The resolution extension method includes normalizing n-m upper bit values of adjacent pixels based on an upper n-m bit value of each pixel of a sample image, analyzing a statistical distribution of a lower m bit value of the reference pixel by patterns of a set consisting of the normalized adjacent pixels, generating a memory address from normalized adjacent pixel values of the sample image, saving a representative value of the lower m bits by patterns to the memory address as a result of the analysis, normalizing adjacent pixel values based on each pixel value of an input image, generating the memory address from the normalized adjacent pixel value of the input image, reading a representative value of the lower m bits saved in the memory address, and adding the read lower m bits to the input image pixel values as lower bits.

    摘要: A bit resolution-extension method is provided. The bit resolution-extension method includes acquiring the shortest distance from a central pixel to a positive contour and the shortest distance from the central pixel to a negative contour in a filtering region which scans the positive contour comprising large pixels of a fixed value and the negative contour comprising small pixels of a fixed value, based on a value of the central pixel, generating an extension bit of the central pixel by interpolating the shortest distance from the central pixel to the positive contour and the shortest distance from the central pixel to the negative contour, and adding the extension bit as a lower bit of the central pixel.

    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.
