摘要： An automatic color adjustment apparatus for use in an imaging device for adjusting the color of a subject such as skin or leave, which is well retained in human memory, to be as natural as possible. The color adjustment apparatus has a weighting coefficient setting device for setting a weighting coefficient according to the difference between the input chromaticity value and the preselected reference chromaticity value set by a chromaticity value setting device. The preselected reference chromaticity value is selected, with respect to a particular subject, such as skin, to be equal to the most natural color of that subject in a chromaticity plane defined by hue and saturation characteristics. The color-adjusted output signal is produced from a calculator which calculates an internal division operation applied to the preselected reference chromaticity value and the input chromaticity signal using the weighting coefficient.

摘要： A color adjustment apparatus includes a color space conversion circuit for obtaining a chromaticity signal in a rectangular coordinate system of a plane representing hue and saturation components. A pointed color chromaticity signal setting circuit sets a pointed color chromaticity signal, which is the prominent color chromaticity signal desired to be changed. A color adjustment area setting circuit sets a color adjustment area of which the center is the pointed color chromaticity signal. A target color chromaticity signal setting circuit sets a target color chromaticity signal. A color conversion circuit generates a converted chromaticity signal (u.sub.h *, v.sub.h *). The converted chromaticity signal is obtained by shifting an original chromaticity signal (u*, v*) by an amount equal to a change from said pointed color chromaticity signal to said target color chromaticity signal. A weighting coefficient setting circuit sets a weighting coefficient (.omega.). And a color adjustment operating circuit generates a corrected chromaticity signal (u.sub.0 *, v.sub.0 *) which is a sum of the converted chromaticity signal and the original chromaticity signal added at the rate of the weighting coefficient (.omega.).
