Zusammenfassung:A luminance variation (dI) pertaining to each pixel is calculated (21) using a plurality of captured images obtained by image capturing under different illumination conditions, a texture variation (dF) pertaining to each pixel is calculated (22) using a plurality of captured images obtained by image capturing at different time points, and a subject region is extracted (23) based on the luminance variation (dI) and the texture variation (dF). A variation in the texture feature (F) pertaining to each pixel between the images is calculated as the texture variation (dF). The subject can be extracted with a high accuracy even when there are changes in the ambient light or the background.
