Gradation transformation property determination unit, the gradation conversion characteristic determining method, the gradation conversion characteristic determination program, image processing apparatus, and image display device

摘要

PPROBLEM TO BE SOLVED: To provide a gradation conversion characteristic determining device capable of determining gradation conversion characteristics used for converting gradation characteristics appropriately, and to provide a method of determining the gradation conversion characteristics and a program for determining the gradation conversion characteristics. PSOLUTION: The gradation conversion characteristic determining device is used to determine the gradation conversion characteristics used in the conversion of the gradation characteristics in original image data, so that desired gradation characteristics can be obtained in display onto a displaying device. A tristimulus value element determination means determines an element having a large value in the tristimulus value of each primary color, based on the value of the tristimulus value to the gradation value of each primary color for composing displayable multi-primary color by the display device. A gradation conversion characteristic determination means determines the gradation conversion characteristics for obtaining desired gradation characteristics, based on the element of the tristimulus value determined by the tristimulus value element determination means. The gradation conversion characteristic determining device enables the gradation conversion characteristics used for converting the gradation characteristics to be set precisely.
