Pixels and picture resolution determine how detailed the image a camera or camcorder captures will be. They are among the most important factors customers should consider before buying a digital camera. In short, the more pixels a camera has, the higher the resolution and the more detail the pictures it captures will be.
Pixels are tiny squares that together make up a digital image. On digital cameras, they're measured in megapixels (MP) and prominently displayed on the camera. 1 megapixel equals 1 million pixels.
Resolution essentially means how large a picture can be enlarged without getting blurry or degrading in quality. A camera with 4-5 megapixels has a medium picture resolution of 2048 x 1536 pixels. That's enough detail for a 5 x 7 print or for emailing or sharing online.
For high resolution 8 x 10 prints, customers will want a camera with 6-8 megapixels for picture resolution of 2272 x 1704 pixels or greater.
Resolution is often the most important factor for a customer to consider when choosing a camera. Customers who plan to take pictures that they want to enlarge or print at the highest quality will want to get a camera with more megapixels because it will deliver higher resolution pictures.
