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 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 processor configured to detect color coordinates of the plurality of reference colors from an object image to be processed, and to identify 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 for each light source in the memory. |
