ABSTRACT:
It is difficult properly to perform correction processing such as white balance adjustment and exposure compensation for all types of images. This invention provides a way in which white balance adjustment and exposure compensation are performed in accordance with image features by considering the arrangements of pixel values in the highlighted and shadow areas of an image. Proper correction processing can therefore be performed for any types of images.
