Note1) In the super fine and fine mode, quantity of information (File size) that image data
has varies even their resolution is the same.(Refer to the Table on the next page for
details.) Therefore, as a result, some differences are seen on the images even with the
same resolution.
q Self-timer mode: Picture will be taken 10 seconds by the clock counter.
q Macro mode range: 0.2m~0.5m
q Multi-frame mode: Continuous taking 9 images in a same picture at four intervals
(total time : 0.5, 1.0, 2.0, 3.0 seconds)
