Abstract
A method and apparatus for enhancing a digital photographic image uses a combination of global and content-specific operations. Image data is analyzed to detect one or more content items in the image to be separately enhanced. Then a content-specific enhancement operation is performed on data representing at least one detected content item, separately from the remainder of the image data. Several such content-specific operations may be performed for different types of content item. The content-specific enhancement operation comprises manipulating data, and the manipulation applies different adjustments to different pixels in the detected content item and the determination of the adjustments is based solely on analysis of the image data. Then a different enhancement operation is performed on at least the remaining image data excluding said one or more detected content items.
