摘要

A binary mask image for extracting subject is generated by binarizing an image after image-processing (processed image) with a predefined threshold value. Based on an image before image-processing (pre-processing image) and the binary mask image for extracting image, a subject image in which only a subject included in the pre-processing image is extracted is generated by eliminating a background region from the pre-processing image.
