Abstract
Abstract The present invention is directed to a method for color correction for images, in particular for digital still camera images, including the following steps: an image is analyzed with respect to particular features assigned to a variety of image classes, each class having particular characteristics; the analysis based on a comparison of the image data of said image with a data base including data for assigning said image to a particular image class; said particular image class is associated with at least one color correction process adapted to implement color correction for the assigned image class.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
95 words
A method for colour correction for images, in particular for digital still camera images, including the following steps: a) an image is analysed with respect to particular features assigned to a variety of image classes, each class having particular characteristics; b) the analysis is based on the comparison of the image data of said image with a data base including data for assigning said image to a particular image class; c) said particular image class is associated with at least one colour correction process being adapted to implement colour correction for the assigned image class.
Claim 2
Independent Claim
95 words
A method for colour correction for images, in particular for digital still camera images, including the following steps: a) an image is analysed with respect to particular features assigned to a variety of image classes, each class having particular characteristics; b) the analysis is based on the comparison of the image data of said image with a data base including data for assigning said image to a particular image class; c) said particular image class is associated with at least one colour correction process being adapted to implement colour correction for the assigned image class.
Claim 3
Dependent Claim
25 words
The method according to claim 1 , wherein one or more probabilities likelihood's are determined that a particular image belongs to one or more classes.
Claim 4
Dependent Claim
34 words
The method according to claim 2 , wherein the most likely class is selected and a colour correction process associated with said selected class is applied to said image or digital image data thereof.
Claim 5
Dependent Claim
40 words
The method according to claim 2 , wherein if several classes are likely to belong to said image, the colour correction processes belonging to said classes are applied to said image, if the corresponding probabilities exceed a particular probability threshold.
Claim 6
Dependent Claim
28 words
The method according to claim 2 , wherein one or more colour correction algorithms or processes are selected and/or combined according to the principals of a Bayesian inference.
Claim 7
Dependent Claim
21 words
The method according to claim 2 , wherein the colour correction processes are applied either with increasing or with decreasing probabilities.
Claim 8
Dependent Claim
23 words
The method according to claim 1 , wherein further imaging information, such as recording information of a specific camera, are taken into account.
Claim 9
Dependent Claim
39 words
The method according to claim 1 , wherein one or more of the known colour correction processes are used to implement said colour correction or colour corrections in accordance with the assignment procedure corresponding to step 1b) and/or 1c).
Claim 10
Dependent Claim
32 words
The method according to claim 1 , wherein images identified as not being colour correctable by means of any of the colour correction processes are transmitted to an operator for colour correction.
