发明名称 Image processing method and apparatus
摘要 An image processing method aims to optimally improve a brightness distribution with respect to brightness of a face being a main subject of a person image. Thus, the method consists of: a brightness component extraction step of extracting a brightness component from image data; a low-frequency brightness component extraction step of extracting a low-frequency component signal of the brightness component as a low-frequency brightness component; a color adjustment step of performing color adjustment to the image data by using the brightness component and the low-frequency brightness component; a first parameter determination step of determining a first parameter; and a second parameter determination step of determining a second parameter in accordance with a distribution of brightness component values in a second area in the image data, wherein the color adjustment step causes processing a degree of the color adjustment according to the first and second parameters.
