Abstract
It is well known that colors indicated on two color devices are different from each other. Gamut compression technique has been required to compress colors displayed onto a monitor with the large gamut to colors displayed on another monitor with the smaller gamut. Although minimizing color different method is commonly used, this method transforms a color ut of smaller gamut to a target color which is on the surface of the smaller gamut. In this method, a target color is set to the intersection of the compression vector toward certain point of L*50 in CIELAB color space and the surface of the gamut. The print is used uniformly for all hue. Therefore we investigated a gamut compression method modified Centroid vector method to adapt the target point of compression vectors for basic 6 hue categories based on subjective experiment using two CRT monitors. We carried out subjective experiments and determined the compression vectors. We compressed the color out of gamut with weights for interpolation calculated in each 6 hue categories. We applied this method to natural images and chart. The result showed this method was effective.
