METHOD AND APPARATUS FOR ENHANCING A DIGITAL PHOTOGRAPHIC IMAGE
First Claim
1. A method for enhancing a digital photographic image, the method comprising processing data representing the image, the processing comprising:
- analysing the data to detect one or more content items in the image to be separately enhanced;
performing a content-specific enhancement operation on data representing at least one detected content item separately from the remainder of the image data, wherein the content-specific enhancement operation comprises manipulating data, and wherein 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; and
performing a different enhancement operation on at least the remaining image data excluding said one or more detected content items.

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.

16. A method for enhancing a digital photographic image, the method comprising processing data representing the image, the processing comprising:
-
using at least two different detection processes to detect one or more content items in the image to be separately enhanced, each detection process being configured to detect a different type of content item in the data representing the image; for each detected content item performing a content-specific enhancement operation on data representing the content item separately from the remainder of the image data, wherein the content-specific enhancement operation comprises manipulating data, and wherein 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. - View Dependent Claims (17)
