Abstract: This study describes an approach of color adjustment extending the technology of adjustment layer. Adjustment layer allows to apply color adjustment to layered images using a separate layer, useful in many graphic utilities, but the parameters of color adjustment cannot be different in different parts of the image. To break this constraint and make a more flexible way of color adjustment, the proposed approach introduced three schemes of blending the color values of two layers, focusing on taking the color values of a basic layer as parameters of three types of color adjustment, making a basic layer function as an augmented adjustment layer. As a result, the tedious work of space-variant color adjustment can conveniently be done by assigning the three schemes to one basic layer and deliberately editing this layer.
