Method of converting color temperatures in image display device using contents description metadata of visual contents and system using the same

Abstract

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.
