Relation between the record mode and the resolution
Resolution
The number of pixels (horizontal
× vertical) used when saving an image. If the
image will be printed, higher resolutions (larger numbers) are recommended
so that the image will be clearer. However, higher resolutions make the file
size (amount of data) larger, so the number of pictures that can be saved will
be fewer.
Resolution and picture size on a computer screen
When a picture is transferred to a computer, the size of the picture on the
computer screen varies depending on the computer’s monitor setting. For
instance, a picture taken in 1024
× 768 resolution is the same size as the
screen if you set the picture to 1 × when the monitor setting is 1024 × 768.
However, if the monitor setting is over 1024 × 768 (such as 1280 × 1024), the
picture only takes up part of the screen.
Compression rate
In record modes other than TIFF, image data are compressed. The higher the
compression rate, the less clear the image.
File format
This camera saves images with either TIFF or JPEG formats. In record
modes other than TIFF, images are compressed in the JPEG format. The
compression rate also varies in each mode.
