On "image quality" and "image size"
A digital image is made up of a collection of small dots called pixels.
If it contains a large number of pixels, the image becomes large, it takes up more memory, and
the image is displayed in fine detail. "Image size" is shown by the number of pixels. Although
you cannot see the differences on the screen of the camera, the fine detail and data processing
time differ when the image is printed or displayed on a computer screen.
Description of the pixels and the image size
Pixels
Selecting the image size for use (page 12)
1 Image size: 10M (DSC-W170 only)
3648 pixels × 2736 pixels = 9,980,928 pixels
2 Image size: 8M (DSC-W150 only)
3264 pixels × 2448 pixels = 7,990,272 pixels
3 Image size: VGA
640 pixels × 480 pixels = 307,200 pixels
Pixel
Many pixels (Fine
image quality and
large file size)
Few pixels (Rough
image quality but
small file size)
Example: Printing in
up to A3+ size
