METHOD AND APPARATUS FOR ACQUIRING MAPPING CURVE PARAMETER

摘要

A method and apparatus for acquiring a mapping curve parameter. The method comprises: acquiring a first mapping curve parameter set and a first target system display maximum brightness (1001); acquiring a display brightness parameter set (1002), wherein the display brightness parameter set comprises the maximum display brightness and/or the minimum display brightness of a display device; acquiring an adjustment coefficient set (1003), wherein the adjustment coefficient set comprises one or more adjustment coefficients, and the one or more adjustment coefficients correspond to one or more parameters in the first mapping curve parameter set; and according to the display brightness parameter set, the first target system display maximum brightness and the adjustment coefficient set, adjusting one or more parameters in the first mapping curve parameter set so as to obtain a second mapping curve parameter set (1004), wherein the second mapping curve parameter set comprises one or more adjusted parameters. By means of the present method, a more accurate hue adjustment can be provided for display devices of different brightnesses, and the flexibility is relatively high.
