With the advance of information communication techniques and semiconductor techniques, various electronic devices are being developed into multimedia devices for providing various multimedia services. For example, a portable electronic device may provide various multimedia services such as a broadcasting service, a wireless Internet service, a capturing service, and a music playback service.
The electronic device may provide various functions for satisfying a demand of a user who wants to easily capture a photo or a moving image through the capturing service. For example, the electronic device may provide an auto capturing function for automatically setting a focus point (a focus) and exposure for a subject so that the user can capture the subject without a special manipulation.
