画像処理装置、画像処理方法及びプログラム
Document Type and Number:
Japanese Patent JP4375325
Kind Code:
B2
Abstract:
The present invention includes a coordinate rotating circuit which executes a coordinate rotating conversion based on a predetermined rotation matrix, on each of two color difference signals to obtain two color difference rotated signals, a normalizing circuit which divides the color difference rotated signal by a luminance signal to obtain a color difference normalized signal, a subtractor and an absolute value calculating circuit which calculate a color saturation degree-of-deviation signal from a difference between the color difference normalized signal and a coefficient, and a tangent circuit and an absolute value calculating circuit which divide the color difference rotated signal by the color difference rotated signal to calculate a hue degree-of-deviation signal from a resulting quotient.
