摘要：
An imaging device condition determination section determines whether a condition of an imaging device is suitable for obtaining light source information. When it is determined to be suitable, a light source image obtaining section obtains a light source image by the imaging device. A first imaging device information obtaining section obtains first imaging device information representing the condition of the imaging device at a point in time when the light source image is obtained. A second imaging device information obtaining section obtains second imaging device information representing the condition of the imaging device at a time of actual image capturing. A light source information estimating section estimates light source information at the time of image capturing by using the light source image and the first and second imaging device information.
