Image processing apparatus and light source identification method |
摘要 |
An image processing apparatus is provided including a storage unit for storing relationships of color coordinates between a plurality of reference colors under each of a plurality of different light sources for each light source, with respect to the plurality of reference colors set in a color space and being different from one another; and a calculation unit for detecting color coordinates of the plurality of reference colors from an object image to be processed, and identifying a light source used in capturing of the object image according to a similarity between relationships of the detected color coordinates and the relationships of color coordinates stored in the storage unit for each light source. |

1. An image processing apparatus, comprising:
a memory configured to store information sets each relating to positional relationships between color coordinates corresponding to a plurality of reference colors under a light source among a plurality of predetermined light sources, wherein the plurality of reference colors are set in a color space, and the information sets respectively correspond to the plurality of predetermined light sources; and a processor configured to detect color coordinates of the plurality of reference colors from an object image, and to identify a light source used in capturing of the object image, based on a similarity between positional relationships of the detected color coordinates and the positional relationships of color coordinates specified by each of the information sets in the memory. |
