Specifying Image Size
“Image size” is the size of the image, expressed as the
number of vertical and horizontal pixels. A “pixel” is one of
the many tiny dots that make up the image. More pixels
provide finer detail when an image is printed, but a higher
pixel count also causes the image’s file size to be larger.
You can select an image size to suit your needs for greater
detail or smaller file size.
Note that this setting is valid for snapshots only. For
information about movie image size, see page 103.
1.In the REC mode, press [MENU].
2.Use [] and [] to select the “Quality” tab.
3.Use [
] and [] to select “Size”, and then
press [].
*“M” stands for “Mega.”
4.Use [
] and [] to select the setting you
want, and then press [SET].
When selecting the image size, the image size value
(pixels) will alternate on the display with a
corresponding print size. The print size indicates the
optimum paper size when you print an image that is
the image size you select.

Specifying Image Quality
Compressing an image before storage can cause a
deterioration of its quality. The more an image is
compressed, the greater the loss of quality. The image
quality setting specifies the compression ratio to be used
when an image is stored in memory. You can select an
image quality setting to suit your needs for higher quality or
smaller file size.
• Note that this setting is valid for snapshots only. For
information about movie image quality, see page 103.
1.In the REC mode, press [MENU].
2.Use [] and [] to select the “Quality” tab.
3.Use [
] and [] to select “ Quality”, and
then press [].
4.Use [
] and [] to select the setting you
want, and then press [SET].
• The above print sizes are all approximate values when
printing at a resolution of 200 dpi (dots per inch). Use a
larger setting when you want to print at a higher
resolution or when you plan to produce a larger size print.
• In order to obtain the level of resolution for which your
camera is designed, recording at a maximum image size
(5M) is recommended. Use a smaller image size when
you want to conserve memory capacity.
• Selecting the “5M (3:2) (2560 ×
 1712 (3:2))” image size
records images with a 3:2 (horizontal:vertical) aspect
ratio, which is optimal for printing on photographic paper
with an aspect ratio of 3:2.

will appear on the monitor screen as shown below to
