Automatic color defect correction
First Claim
1. Method for automatically correcting color defective areas in an image, said defective color areas being recorded with a color spectrum deviating from the actual color spectrum of said areas without color defects, comprising the steps of:
- a) identifying basic areas in the image on the basis of features which are common for recorded defective areas, said basic areas supporting an increased likelihood of including defective areas;
b) reducing a processing to the basic areas to identify at least one of borderlines and centers of the defective areas;
c) identifying whether the basic areas deemed to be defective are defective; and
d) creating a correction mask to correct a visual appearance of the defective area if a basic area has been identified to be defective.

Abstract
The present invention refers to a method for automatically correcting color defective areas in an image, which defective color areas were recorded with a color spectrum deviating from the actual color spectrum of said areas without color defects, wherein basic areas in the image are identified on the basis of features which are common for these recorded defective areas, said basic areas supporting an increased likelihood to include defective areas, and the processing is then reduced to the basic areas to identify borderlines and/or centres of the defective areas, and afterwards, it is identified whether the localized basic area or areas deemed to be defective are defective or not, and finally, if a localized basic area has been identified to be defective, a correction mask is created to correct the visual appearance of the defective area.

20. An image processing device for processing image data, comprising:
-
an image data input section;
an image data processing section;
an image data recording section for recording processed image data, wherein the image data processing section implements a method for automatically correcting color defective areas in an image, said defective color areas being recorded with a color spectrum deviating from the actual color spectrum of said areas without color defects, including the steps of;
