摘要： A color temperature conversion method, medium, and apparatus converting an image from one of a plurality of basic color temperatures provided by an image display device to another color temperature other than the plurality of basic color temperatures. Also, the conversion method and apparatus enable pixels of the image with different brightnesses to have different color temperatures according to a user' preference. The color temperature conversion method includes: calculating variables for determining a conversion range; determining whether based on the calculated variables the input pixel is to be color-temperature-converted by determining whether the input pixel is within the conversion range; and 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.

摘要： A multiple color transformation apparatus and method for an image and a computer readable recording medium storing a computer program therefore are provided. The multiple color transformation apparatus includes a middle status chrominance component producer which linearly combines first through Mth (where M is a positive integer larger than “3”) input chrominance components to represent a color of each of pixels of the image to produce first through Nth (where N is greater than or equal to M) middle status chrominance components; and a chrominance component compensator which relatively differently adjusts luminance levels of the first through Nth middle status chrominance components according to degrees to which the first through Nth middle status chrominance components contribute to representing a single color and outputs the first through Nth middle status chrominance components having the adjusted luminance levels as color-compensated first through Nth middle status chrominance components. Therefore, using the multiple color transformation apparatus and method, a number of input chrominance components can be transformed into a variety of chrominance components while maximizing a luminance and color saturation of an image display device.
