Abstract
Official abstract text for this publication.
A color conversion method, medium, and apparatus, converting a color temperature of 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 may include determining a first information associated with a conversion range, 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, calculating color coordinates of a target point if 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 an 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.
First claim
Opening claim text (preview).
What is claimed is: 1. A color temperature conversion method for an image signal having pixels, each pixel having a brightness signal and color difference signals, converting a color temperature of an input pixel based on a brightness of the input pixel, the color temperature conversion method comprising: determining first information associated with a conversion range at a first calculation unit; determining whether the color temperature of the input pixel needs to be converted…
