Embodiment Construction
[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0030] A color gamut extension mapping method for laser TV, its steps are:
[0031] Step 1) Sample the surface of the RGB color cube.
[0032] Set one of the three variables R, G, and B to 0 or the maximum value, and then change the values of the other two variables uniformly according to the set step size (1 / 16 of the maximum value); the sampling point is at The RGB space is evenly distributed on six planes, and the sampling points on each plane can form a series of triangles.
[0033] The construction process of the triangle is as follows, taking the R=0 plane as an example, the R component is 0, the G and B components take 16 as the step size, and sample uniformly within the range of 0-255, resulting in 256 sampling points. As shown in the figure, the points (0, 0, 0), (0, 0, 16), (0, 16, 0), (0, 16, 16) form two triangles, and so on, R=0 plane ...
