Abstract
一种光源估测方法、图像处理方法和相关产品。这种光源估测方法通过将图像切分的子块的色彩亮度信息组映射到色彩亮度三维空间,得到位于色彩亮度三维空间中的多个色彩亮度样点,并对多个色彩亮度样点进行分层分群处理,进而通过计算各层的色彩亮度样点分群的交融度来计算整个图像的交融度,并据此估测所述图像的拍摄环境中是否存在多个色温不同光源的情况。由于这种光源估测方法可在一定程度上估测所述图像所对应拍摄环境中是否存在多个色温不同光源的情况,那么,这为基于包括多个色温不同光源的情况进行相应图像校正奠定了基础,使得在包括多个色温不同光源的情况下进行针对性图像校正变得可能,进而有利于提升图像校正的针对性和合理性。
