Record mode
You can select a record mode in which to take pictures or shoot movies.
Select the best record mode for your purpose (printing, editing on a
computer, website editing, etc.). For information on the image sizes for
each record mode and memory capacity, see the table on P. 27.
Record mode depicts the image size and compression rate of pictures you wish to
record.
Pictures are made from thousands of dots (pixels). If a picture with relatively few
pixels is enlarged, it looks like a mosaic. A picture with many pixels is denser and
clearer, but requires a larger file size (data size), decreasing the number of pictures
that can be saved. Increasing the compression rate reduces the file size, but makes
the pictures appear grainy.
Image size
The number of pixels (horizontal × vertical) used when saving an image. Save your
pictures in a large image size to get clearer prints.
Compression
Image data is compressed and recorded. The higher the compression, the less clear
the image will be.
