Image size and quality
You can choose image size (number of
pixels) and image quality (compression
ratio) based on the kind of images you
want to shoot.
The image size is shown by the number
of pixels (dots) (horizontal × vertical),
which compose an image. For example, a
7M (3072×2304) size image indicates that
there are 3072 pixels horizontally and 2304
pixels vertically. The larger the number of
pixels, the larger the image size.
You can select from Fine (high quality)
or Standard image quality. Each uses a
different compression ratio.
When you select Fine, the image quality
improves as the image size increases,
but the amount of recorded data also
increases and the number of images that
can be recorded on a recording medium
decreases. Refer to the table on the right
and choose the image size and image
quality appropriate to the kind of images
you want to shoot. Short description of the image size
