摘要： An apparatus to detect a color gamut boundary using a spherical coordinate system and an interpolation scheme, and a mapping apparatus and method using the same. The method for detecting a color gamut boundary includes converting color coordinate values of input color samples to spherical coordinate system values (γ, θ, α); performing interpolation by adding at least a color coordinate value by using adjacent color coordinate values when there is one having no color coordinate value of a given number of segments, the spherical coordinate system being uniformly divided into the given number of segments; detecting one having the largest radius r of color coordinate values positioned in the segment for each divided segment; and detecting one closest to a center of each segment of the detected color coordinate values having the largest radius for each segment to detect the color gamut boundary. Thus, it is possible to make an accurate color gamut boundary descriptor.

摘要： A method of visually measuring the brightness of ambient lighting around a display device is disclosed. In this method, first, a reference brightness of the display device is determined according to a type of display device. Thereafter, information about locations where the display device is used is received from the user, and illuminance values of the display device corresponding to brightness stages are set based on the reference brightness and the location information. Then, a reference brightness is converted into each of the illuminance values corresponding to each of the brightness stages. The converted images with the illumination values corresponding to the brightness stages are displayed to the user, and an image that has a brightness value nearest to the brightness of ambient lighting is selected, and the brightness value of the selected image is determined as the brightness of ambient lighting.
