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.
摘要翻译：提供了一种用于自动白平衡（AWB）的图像分类装置和方法。输入图像被分成包括多个像素的块。为每个块计算色调值和色度值。通过针对每个块计算针对与该一个块相邻的所有块计算的色调和色度值之间的差异以及为该块中的一个块计算的色调和色度值来检测颜色变化块。如果检测到的颜色变化块的数量大于或等于第一阈值，则针对整个输入图像计算色调方差和色度方差。如果色调方差大于或等于第二阈值或色度方差大于或等于第三阈值，则输入图像被确定为非单色图像。

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.
