Notes
z 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
