Apparatus and method for adjusting color temperature of displayed image using color temperature metadata

A method for providing image metadata, comprising:

• (b) calculating the color temperature of a predetermined input image;
• (c) dividing a color temperature range into a plurality of color temperature sections and generating metadata using information on a color temperature section to which the color temperature of the input image belongs;
• and
• (d) storing the metadata and transmitting the input image and its corresponding metadata to a user terminal.

An apparatus for adjusting the color temperature of an image, comprising:

• a metadata decoding unit which receives metadata containing information on the color temperature of the image, identifies a color temperature section to which the color temperature of the image belongs, converts the color temperature section into a reciprocal color temperature section, identifies a reciprocal color temperature sub-section to which the color temperature of the image belongs, and then determines a color temperature of an image to be output;
• a color temperature conversion unit which receives the image and adjusts the color temperature of the image based upon the determined color temperature and a preferred color temperature input from a user;
• and
• an output unit which outputs the image having the adjusted color temperature to the user.

A method for adjusting the color temperature of an image, comprising:

• (a) receiving metadata containing information on the color temperature of the image and identifying a color temperature section to which the color temperature of the image belongs;
• (b) converting the color temperature section into a reciprocal color temperature section, identifying a reciprocal color temperature sub-section to which the color temperature of the image belongs, and then determining a color temperature of an image to be output;
• (c) receiving the image and adjusting the color temperature of the image based upon the determined color temperature and a preferred color temperature input from a user;
• and
• (d) outputting the image having the adjusted color temperature to the user.

A system for adjusting the color temperature of an image using metadata, comprising:

• a color temperature calculation unit which receives a predetermined image and calculates the color temperature of the 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;
• a metadata database which stores the metadata corresponding to the predetermined image and transmits the metadata to a user terminal;
• a metadata decoding unit which receives metadata containing information on the color temperature of the image, identifies a color temperature section to which the color temperature of the image belongs, converts the color temperature section into a reciprocal color temperature section, identifies a reciprocal color temperature sub-section to which the color temperature of the image belongs, and then determines a color temperature of an image to be output;
• a color temperature conversion unit which receives the predetermined image and adjusts the color temperature of the image based upon the determined color temperature and a preferred color temperature input from a user;
• and
