Color temperature conversion method and apparatus that convert color temperature of pixel based on brightness of pixel

摘要

Provided are a color conversion method and apparatus, which convert color temperature an image to a user-set color temperature on a pixel-by-pixel basis based on the brightness of each pixel of the image. The color temperature conversion method include: (a) determining first information associated with a conversion range; (b) determining whether the color temperature of the input pixel needs to be converted by determining based on the first information whether the input pixel is within the conversion range; (c) calculating color coordinates of a target point if the input pixel is within the conversion range; and (d) converting the color temperature of the input pixel by moving in the same direction as the reference point to the target point in amount proportional to the reference point displacement so that the input pixel can be automatically moved along with the reference point of the conversion range.
