Abstract
First image data is obtained by performing an image capturing operation with a flash and, subsequently, second image data is obtained by performing an image capturing operation without a flash. By using data of a differential image between the first and second image data and a relative spectral distribution of flash light, the spectrum reflectivity in a position on a subject corresponding to each pixel is obtained and object-color component data is acquired as data from which an influence of an illumination environment has been removed. On the other hand, illuminant component data indicative of spectral distributions of a plurality of illumination light are prepared. By combining arbitrary illuminant component data to the obtained object-color component data, an image with a different illumination environment can be reproduced.
