Title:
COLOR ADJUSTMENT DEVICE
Document Type and Number:
Japanese Patent JP3173140
Kind Code:
B2
Abstract:
PURPOSE: To adjust the color selectively with simple configuration by keeping the continuity of the color.
CONSTITUTION: A characteristic used to convert a noted color into an object color based on a noted color chromaticity signal set by a noted color chromaticity setting means 2 and representing a center of a color region desired to be converted in a chromaticity plane representing a hue component and a saturation component and on an object color chromaticity signal set by an object color, chromaticity setting means 3 and representing a color after desired conversion is set to a 1st color conversion means 5. Then a weight coefficient decision means 6 decides the weight coefficient in response to a difference between the inputted chromaticity signal and the noted color chromaticity signal set by the noted color chromaticity setting means 2, and a color adjustment arithmetic means 7 decodes an output color signal in response to an output of the weight coefficient decision means 6 based on an output of the 1st color conversion means 5 and the inputted chromaticity signal.
