ABSTRACT:
To determine a more appropriate WB gain. A first image data, which is obtained by way of photographing essentially the same subject as that of a main image intended by a user without firing a strobe light for preliminary illumination, and a second image data, which is obtained by way of photographing the same while firing the strobe light for preliminary illumination, are captured. Subsequently, a typical value of each of blocks constituting the first and second image data and the type of a light source of the same are acquired as block information. The thus-acquired pieces of block information about the first and second image data are compared with each other, to thus acquire the tendency of a color change in subject before and after preliminary illumination. An environment light source is estimated on the basis of the obtained tendency of a color change.
