Abstract
Different color output devices generally possess different color
gamut. The visual description of color gamut on an output device is
very significant for understanding the performance of the equipment
and predicting color image output effect. Based on the layer cutting
method on the lightness axes’ chromaticity coordinate, this
paper provides a new way to obtain the scattered point cloud of layer,
extract boundary sample points of scattered point cloud, and achieve
the device gamut boundary curve on slice with the use of piecewise
quadratic B-spline curves. All boundary curves of the same device
can be shown in the same coordinate system with this method, and ultimately
the entire color gamut visualization result of the output device can
be achieved. This method provides a new idea on the gamut visualization
parametric modeling for different color output devices, and also provides
a good way for the non-distorted evaluating system of the color transferring
from the color display device to the color output device.
