    • Upon extraction of a human figure region in an image, a face or facial part is detected in the image, and a candidate region that is deemed to include the human figure region is determined from position information of the detected face or facial part. Judgment is made as to whether each unit region having 2 pixels or more and comprising the candidate region represents the human figure region, and a set of the unit regions having been judged to represent the human figure region is determined as an estimated region which is estimated to include the human figure region. The human figure region is then extracted in the determined estimated region.
    • 在提取图像中的人物图形区域时,在图像中检测到面部或面部部分,并且根据检测到的面部或面部部分的位置信息确定被认为包括人体图形区域的候选区域。 判断具有2个像素以上并且包含候选区域的单位区域是否表示人物图像区域,并且将被判断为表示人物图像区域的单位区域的集合确定为估计的估计区域 包括人物地区。 然后在确定的估计区域中提取人体图像区域。
