Method and apparatus for generating user preference data regarding color characteristic of image and method and apparatus for converting image color preference using the method and apparatus
First Claim
1. A method for generating user preference data regarding a color characteristic of an image, when an image converted to have a color characteristic that a user prefers with respect to a predetermined reference image is referred to as a preference image, a color characteristic value of the preference image is referred to as a preference value and a color characteristic value of the reference image is referred to as a reference value, the method comprising:
- (a) generating {preference value, reference value} which corresponds to a pair of the preference value and the reference value; and
(b) generating the pair {preference value, reference value} as preference meta-data having at least one feature block,wherein the feature block comprises;
a block header including a feature identifier corresponding to information identifying a color characteristic; and
at least one feature descriptor including the preference value and the reference value.

Abstract
A method and apparatus for generating user preference data regarding the color characteristic of an image and a method and apparatus for converting image color preference using the method and apparatus is provided. The method for generating user preference data comprises (a) obtaining an image color characteristic value of a preference image and a reference image, (b) generating {preference value, reference value} which corresponds to a pair of the preference value and the reference value, and (c) generating the pair {preference value, reference value} as preference meta-data having at least one feature block. The method for converting image color preference comprises calculating a color characteristic value with respect to an input image, generating preference meta-data having at least one feature block, the feature block comprising a block header including a feature identifier corresponding to information identifying a color characteristic and at least one feature descriptor including the preference value and the reference value, obtaining a color characteristic value with respect to the input image using the calculated color characteristic value of the input image and the color preference data, and converting the color characteristic of the input image so that the input image has the obtained color characteristic value.

21. An apparatus for generating user preference data regarding a color characteristic of an image, when an image converted to have a color characteristic that a user prefers with respect to predetermined reference image is referred to as a preference image, a color characteristic value of the preference image is referred to as a preference value and a color characteristic value of the reference image is referred to as a preference value and a color characteristics value of the reference image is referred to as a reference value, the apparatus comprising:
-
a color characteristic calculating unit, which obtains an image color characteristic value of the preference image and the reference image, and generates {preference value, reference value} which corresponds to a pair of the preference value and the reference value; and a meta-data generating unit, which generates the pair {preference value, reference value} generated in the color characteristic calculating unit as preference meta-data having at least one feature block, wherein the feature block comprises; a block header including a feature identifier corresponding to information identifying a color characteristic; and at least one feature descriptor including the preference value and the reference value. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
