A method and apparatus for generating user preference data regarding the color characteristic of an image is provided where a preference image comprises an image converted to have a color characteristic that a user prefers with respect to a predetermined reference image, a preference value comprises a color characteristic value of the preference image, and a reference value comprises a color characteristic value of the reference image. 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.

An apparatus for providing image metadata includes an input unit, an image metadata decoding unit, and an image color temperature converting unit. The input unit receives an input image, metadata corresponding to the color temperature of the input image, and color temperature information preferred by a user. The image metadata decoding unit calculates a color temperature corresponding to the metadata. The image color temperature converting unit converts the color temperature of the input image using the color temperature calculated by the image metadata decoding unit and the color temperature information preferred by a user.

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.

摘要:
Provided are a method of and a system for converting color temperatures of visual contents to user's preferred color temperatures by using metadata of the visual contents. The system includes an image color temperature recording unit, a user preferable color temperature managing unit, and a color temperature adjusting unit. The image color temperature recording unit time-divides the visual contents according to a color temperature description format, estimates color temperatures of time-divided sections, and records the estimated color temperatures as first metadata. The user preferable color temperature managing unit determines user's preferable color temperatures of the time-divided sections, records the user's preferable color temperatures as second metadata, and outputs the user's preferable color temperatures. The color temperature adjusting unit converts the estimated color temperatures of the first metadata based on the user's preferable color temperatures of the second metadata.
摘要:
There are provided an apparatus and a method for adjusting the color temperature of an input image using metadata corresponding to the color temperature of the input image. The apparatus includes a color temperature calculation unit which receives a predetermined image and calculates the color temperature of the predetermined image, a metadata generation unit which divides a color temperature range into a plurality of color temperature sections and generates metadata using information on a color temperature section to which the color temperature of the predetermined image belongs, and a metadata database which stores the metadata corresponding to the predetermined image and transmits the metadata to a user terminal.
