Provided is a method of controlling a digital image processing
apparatus that processes and stores an input image in a recording medium and reproduces files stored in the recording
medium in a stored-image display mode. The method
includes: (a) classifying the stored-image display mode into
first and second modes; (b) determining whether any one of
the first and second modes was selected by a user if a command to perform the stored-image display mode is input by
the user; (c) displaying a latest file first if the first mode was
selected; and (d) displaying a file most recently reproduced
first if the second mode was selected.
