Abstract
A photographing method and apparatus are provided. In the method, an image signal of an object region is detected from an input image signal, a shadow region is detected from the object region image signal, and an image signal obtained by superimposing the shadow region on the object region image signal is displayed. When removal of a shadow is requested after the input image signal is captured, the photographing method corrects a brightness level of the shadow region. The photographing apparatus includes an object region detecting unit configured to detect an image signal of an object region from an image signal; a shadow region detecting unit configured to detect a shadow region from the object region image signal, and an image signal superimposing unit configured to output an image signal detected by superimposing the shadow region detected by the shadow region detecting unit onto the object region image signal detected by the object region detecting unit.
