Abstract: A digital image processing apparatus and a method of controlling the same. When the composition of a subject displayed on a display of the apparatus is changed during application of a first shutter-release signal, a current auto-focus (AF) region moves along with the subject and displayed on the display at the same time as the subject. The apparatus can further display an initial AF region on the display in a manner distinguishable from the current AF region. After the composition of the subject is changed, while the current AF region moving along with the subject is being displayed on the display, when the application of the first shutter-release signal is interrupted, an AF region is reset as the initial AF region. Also, an image file can be generated and stored after application of a second-shutter release signal which occurs after application of the first shutter-release signal.
