Disclosed are a method and apparatus for providing metadata for a sensory effect, a computer-readable recording medium on which metadata for a sensory effect are recorded, and a method and apparatus for reproducing a sensory effect. A method for providing metadata for a sensory effect includes generating Sensory Effect Metadata (SEM) including sensory effect information on contents using binary representation syntax; and analyzing the SEM and transmitting the SEM to a sensory reproduction apparatus engine unit that generates control information on a sensory reproduction apparatus. In the method, the sensory effect information includes color correction effect information on the contents.

An apparatus for matching colors between various image devices includes a characterization model generation unit configured to generate characterization models for color conversion using gamut information on the image shooting device and the output imaging device; a color conversion unit configured to convert all colors corresponding to a gamut of the image shooting device into colors corresponding to a gamut of the output imaging device using the characterization models; a lookup table generation unit configured to generate a lookup table between the image shooting device and the output imaging device based on color conversion information of the colors corresponding to the gamut of the image shooting device; and an image conversion unit configured to generate an output image of the output imaging device, of which the colors are matched with those of the image inputted from the image shooting device, using the lookup table.

Apparatus and method for matching colors between various image devices

Provided is a color conversion system and method. The color conversion system which converts the color of a filmed image includes: an image separation unit configured to receive a reference image including a color reference table and an action image, and separate the reference and action images from each other; a color data extraction unit configured to output color values of the color reference table included in the reference image; a control unit configured to detect change values obtained by comparing color values included in the reference image with those included in the color reference table, and generate a look-up table for converting the colors of the color reference table included in the reference image into desired colors; and an image conversion unit configured to perform color correction by converting the color values of the action image into coordinates in pixels, using the look-up table outputted from the control unit.
