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 method and an apparatus are provided for adjusting white balance of a digital image. An input image is converted into a YCbCr color space. White pixels of the converted input image are detected by determining whether each pixel of the converted input image is included in a preset region of the YCbCr color space. A gain of each channel is calculated from averages of R, G and B values of the detected white pixels. White balance adjustment is performed by applying the calculated gain of each channel to each pixel of the input image.
