Abstract
Device and method for color adjustment for adjusting white color of an image including a weight generating unit, a color shift value generating unit, and an adjustment unit. The weight generating unit receives a first color value of the image and generates a weight according to the first color value. The color shift value generating unit receives the first color value and the weight and generates a color shift value according to the first color value and the weight. The adjustment unit receives the first color value and the color shift value and generates a second color value according to the first color value and the color shift value.
Claims19
A color adjustment device for adjusting the white color of an image, said device comprising:
- a weight generating unit for receiving a first color value of said image and generating a weight according to the first color value;
- a color shift value generating unit for receiving said first color value and said weight and generating a color shift value according to said first color value and said weight;
- and
- an adjustment unit for receiving said first color value and said color shift value and generating a second color value according to said first color value and said color shift value.
A color adjustment device for adjusting the white color of an image, said color adjustment device comprising:
- a grey level generator for receiving a first color value of said image and generating a grey level;
- a grey level transform unit for receiving said grey level and generating a color shift transform value;
- a color shift value calculator for receiving said color shift transform value and generating a color shift value;
- and
- an adjustment unit for receiving said first color value and said color shift value and generating a second color value according to said first color value and said color shift value.
A method for color adjustment for adjusting the white color of an image, said method comprising:
- receiving, at a weight generating unit, a first color value of said image and generating a weight based on the first color value;
- receiving, at a color shift value generating unit, said first color value and said weight and generating a color shift value based on said first color value and said weight;
- and
- receiving, at an adjusting unit, said first color value and said color shift value and generating a second color value based on said first color value and said color shift value.
