专利汇可以提供Display color selection method专利检索,专利查询,专利分析的服务。并且PURPOSE: To most property select a small number of colors from a large-sized pallet by determining counts of plurality of points in consideration of weights corresponding to distances between a point corresponding to a previously selected display color and plurality of other points with respect to a color cube and selecting the color corresponding to the point having the maximum count as the next display color.
CONSTITUTION: A three-dimensional color histogram which has axes corresponding to red, green, and blue is generated, and a first color is selected in accordance with the point having the maximum value in the histogram. Thereafter, the point, which is closest to the previously selected point and has the highest frequency, in the histogram is weighted most lightly, and points which are less close to the previously selected point and have high frequencies are weighted heavily. A color is selected in accordance with a weighting algorithm. After a display color is selected, a cluster analysis technique is used to perform optimization. Thus, a limited number of colors are most properly selected from the large-sized pallet to digitize a color image.
