Quality 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 picture 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.

Selecting the image quality (compression ratio) in combination (page 32)
You can select the compression ratio when digital images are saved. When you select a high
compression ratio, the image lacks the fineness of detail, but has a smaller file size.
1 Image size: 6M
2,816 pixels × 2,112 pixels = 5,947,392 pixels
