Method of controlling digital photographing apparatus for efficient replay operation, and digital photographing apparatus adopting the method

A digital photographing apparatus, the apparatus comprising:

• an optical system that receives light from a subject to be photographed by the apparatus;
• a digital signal processor that receives signals representing the light received by the optical system and converts the signals into an image;
• a storage medium for storing at least one image file;
• a display screen for displaying the image files;
• a user input unit including at least one button capable of performing at least two functions while operating under a single condition, wherein a first function of the at least one button is to move a display region of a displayed image and a second function of the at least one button is to display a next image file in a forward direction or a next image file in a reverse direction on the display screen;
• means for performing the first function of the at least one button if a first operating signal is generated;
• and
• means for performing the second function of the at least one button if a second operating signal containing the first operating signal is generated.

A digital camera comprising:

• means for obtaining an image of a subject to be photographed;
• means for storing at least two image files;
• means for displaying an image file;
• means for commanding the digital camera to display the image file in an enlarged mode and a non-enlarged mode;
• means for generating a first operating signal to direct the camera to perform a first function under a first condition, wherein the first function is to move a display region of a displayed image;
• means for generating a second operating signal to direct the camera to perform the first function under a second condition;
• and
• means for generating a third operating signal to direct the camera to perform a second function under a second condition, wherein the second function is to display a next image file in a forward direction or a next image file in a reverse direction.
