Abstract:
1. A method that keeps pixels from a first color space in the range of a second color space, wherein the pixels have a color and brightness, the method comprising: detecting when pixels in the first color space exceed the range of pixels in the second color space with a circuit; restricting the pixels in the first color space to the range of the second color space; defining a sub-space within the first color space using a set of parameters; and determining whether a pixel is outside the sub-space or inside the sub-space, wherein the sub-space approximates the range of the second color space and comprises values from the first color space that are outside the second color space; and wherein defining the sub-space within the first color space further comprises determining values in the first color space that correspond to the boundaries of the sub-space comprising values from the first color space that are outside the second color space.
