You can scale an image to make it larger or smaller, but you can't create pixels out of nothing; if you scale it to have fewer pixels, then you're losing detail, and if you scale it to have more pixels, then you have to guess at the value of the new pixels by averaging nearby pixels. Both of these tend to make the picture look more blurry.
Each "pixel" is a part of the image that remembers a very small part of the digital picture. It is due to the huge number of pixels (megapixel = 1,000,000 pixels) that your digital images retain so much detail. Just remember, the more megapixels, the more detail... but it doesn't necessarily mean a better photo!
Any digital image is made of pixels - the more pixels in the image, the greater the detail and the greater the clarity.
resolution is the term used to describe the number of dots,or pixels,used to display an image.
Resolution
The number of pixels does matter to an extent as to the picture quality.
Yes, the number of pixels on a monitor is known as its resolution.
WUXGA has the greatest number of pixels, however for video, almost all video is in 1080 as a maximum resolution. WUXGA will display this video whilst maintaining the 16:9 aspect ratio with 60 pixels above and below the image
Depends of the number of pixels per centimetres or inch (Ppi- pixel per inch).
Bytes, the higher the mega pixels, the more detail, the more bytes.
