Color gamut boundary detection apparatus of a color device and method the same and method for calculating of color space inverse conversion function

摘要

It discloses a method to obtain the color gamut detecting apparatus and method using the same and the color space inverse transform function of a color device. Gamut detecting apparatus of a color device is the intersection point detection section for detecting the color gamut of the intersection of the plane and having a boundary surface with a certain color of the color-space transform unit, a first color signal and outputting a first color signal to convert the input color signal in a device-independent color space, It shall be, and characterized in that it comprises a vector control computing unit for calculating a control vector corresponding to the source color values ​​of the detected intersection points. Thus, the apparatus can use the intersection of the plane with a certain color or certain brightness plane in the independent color space to obtain an accurate color gamut by determining the control vector at the device-dependent color space. ; Gamut, vector control, color device, and inverse functions
