摘要： Disclosed is color conversion method using a color look-up table. The method includes the steps of: generating a color look-up table using information on the difference of each channel before and after a conversion of each color; and converting the colors using the generated color look-up table. The step of generating the color look-up table includes identifying the maximum difference value among several difference values and generating a first compressed table to initially compress the difference values using the maximum difference value. Further, the step of generating the color look-up table further includes determining, using a predetermined algorithm, whether precedence bits can be removed in the difference values stored in the first compressed table, if yes, removing the corresponding checked bits and storing the converted channel value in a separate auxiliary color table and, if no, storing an index relating to the auxiliary color table as the corresponding difference value, and generating a secondary compressed table that secondarily compresses the initially compressed difference value and adding type information that indicates if information stored as each difference value is the difference value or the index.

摘要： An image classification apparatus and method for Automatic White Balance (AWB) are provided. An input image is divided into blocks including pluralities of pixels. A hue value and a chroma value are calculated for each of the blocks. A color-changed block is detected by calculating, for each one of the blocks, differences between the hue and chroma values calculated for all blocks adjacent to the one of the blocks and the hue and chroma values calculated for the one of the blocks. A hue variance and a chroma variance are calculated for the entire input image if a number of the detected color-changed blocks is greater than or equal to a first threshold. The input image is determined as a non-monochromatic image, if the hue variance is greater than or equal to a second threshold or the chroma variance is greater than or equal to a third threshold.

摘要： A lens shading correction method and apparatus are provided for removing vignetting occurring in digital images due to lens shading. A white image captured by an image pickup device and an image pickup unit is separated into reference white images corresponding to color channels. A vignetting center having a maximum light intensity is estimated in each of the reference white images. Multiple reference segments on each of the reference white images are defined. A lens shading correction value corresponding to each pixel constituting the reference segments are calculated using a corresponding light intensity. A lens shading correction function corresponding to each reference segment is derived using a corresponding lens shading correction value. Vignetting of a general image received in a general image processing mode is removed, using the derived multiple lens shading correction functions.
