Apparatus and method for converting metadata color temperature and apparatus and method for providing metadata

An apparatus for converting a metadata color temperature, comprising:

• an input unit which receives an input image, metadata corresponding to the color temperature of the input image, and color temperature information preferred by a user;
• an image metadata decoding unit which calculates a color temperature corresponding to the metadata;
• and
• an image color temperature converting unit which 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 for providing image metadata, comprising:

• receiving a predetermined image signal and finding color temperature information from the image signal;
• receiving the color temperature information, converting the color temperature information into metadata, and storing the metadata in a database;
• and
• transmitting the metadata as well as the image signal to a user terminal over a communication network in response to the request of the user terminal.

A method for converting the color temperature of metadata, comprising:

• receiving a predetermined input image, metadata corresponding to the color temperature of the input image, and color temperature information preferred by a user;
• calculating the color temperature corresponding to the metadata;
• and
• converting the color temperature of the input image using the color temperature calculated based on the metadata and the color temperature information preferred by a user.
