abstract

The term "color temperature" represents the color of light source or the white point of image displaying devices such as TV and PC monitor. By controlling the color temperature, we can convert the reference white color of images. This is equivalent to the illuminant change, which alters all colors in the scene. In this paper, our goal is to find an appropriate method of converting the color temperature in order to reproduce the user-preferred color temperature in video displaying devices. It is essential that the relative difference of color temperature between successive image frames should be well preserved as well as the appearance of images should seem natural after applying the user-preferred color temperature. In order to satisfy these conditions, we propose an adaptive color temperature conversion method that estimates the color temperature of an input image and determines the output color temperature in accordance with the value of the estimated one.
