Image processing apparatus, image processing system, image processing method, and storage medium

摘要

An image processing apparatus includes a skin information obtaining unit that extracts a skin area from an image and obtains skin information from the skin area; an independent component extracting unit that extracts independent components constituting the skin area from the skin information; and a bias calculation unit that calculates, based on the independent components, a bias representing color information of a light source used to illuminate the skin area when the image is captured.

主权项

1. An image processing apparatus, comprising:
a memory that stores a program; and a processor that executes the program stored in the memory to perform a process, the process including
extracting a skin area from an image and obtaining skin information from the skin area,extracting independent components including melanin pigment components, hemoglobin pigment components, and shading components that constitute the skin area from the skin information,obtaining a smallest component of the melanin pigment components, a smallest component of the hemoglobin pigment components, and a smallest component of the shading components, andcalculating, based on a sum of at least the obtained smallest component of the melanin pigment components and the obtained smallest component of the hemoglobin pigment components, a bias representing color information of a light source used to illuminate the skin area when the image is captured.
