The amount of detail a camera can capture is called the resolution, and it is measured in pixels. The more pixels a camera has the more detail it can capture and the larger pictures can be without becoming blurry. The word "pixel" means picture element. Every picture, in digital form, is made up of pixels. They are the smallest units of information that make up a picture. One of the main ways that manufacturers categorize their digital cameras is in terms of pixel count. This is the number of individual pixels that go into making each image. A million pixels is abbreviated to MP, so a 1MP camera has 1 million pixels and a 3MP camera has 3 million pixels.
Most Digital cameras have a "quality" setting that changes how many pixels they actually record. Unless you have your quality setting on the highest level, you are not taking full advantage of your camera's recording capabilities. Keep in mind that for a point and shoot camera, beyond a certain point (probably around 4 to 5 megapixels), more megapixels will not necessarily yield a better image. Other issues, like lack of overall image sharpness due to poor image or lens quality, or poor lighting, will limit the usefulness of more megapixels.
Some scholars say the human eye can see up to 576 megapixels but only 7 megapixels matter.
