WHAT is a megapixel i looked on dictionary.com but i still dont get it?

Question

is more better or less??

Answer 1

A pixel is generally thought of as the smallest complete sample of an image. The definition is highly context sensitive; for example, we can speak of printed pixels in a page, or pixels carried by electronic signals, or represented by digital values, or pixels on a display device, or pixels in a digital camera (photosensor elements). This list is not exhaustive, and depending on context there are several synonyms that are accurate in particular contexts, e.g. pel, sample, byte, bit, dot, spot, etc. We can also speak of pixels in the abstract, or as a unit of measure, in particular when using pixels as a measure of resolution, e.g. 2400 pixels per inch, 640 pixels per line, or spaced 10 pixels apart.
The more pixels used to represent an image, the closer the result can resemble the original. The number of pixels in an image is sometimes called the resolution, though resolution has a more specific definition. Pixel counts can be expressed as a single number, as in a "three-megapixel" digital camera, which has a nominal three million pixels, or as a pair of numbers, as in a "640 by 480 display", which has 640 pixels from side to side and 480 from top to bottom (as in a VGA display), and therefore has a total number of 640 × 480 = 307,200 pixels or 0.3 megapixels.

Answer 2

megapixel




- A megapixel (that is, a million pixels) is a unit of image sensing capacity in a digital camera. (A pixel - a word invented from "picture element" - is the basic unit of programmable color on a computer display or in a computer image.) In general, the more megapixels in a camera, the better the resolution when printing an image in a given size. A digital camera with a 1.3 megapixel resolution will print a good quality 4 x 3 inch print at 300 dpi (dots per inch). If a higher quality is needed or a larger print at the same quality, a camera with a higher megapixel value will be needed.
The number of images that can be stored in a given size of flash memory for the camera is determined by the size of the flash memory and the size of each image in terms of megapixels.

Answer 3

Think of pixels as dots. If you are using a few dots to create a picture of an apple, the picture isn't going to be very clear but if you have a whole bunch of dots, then your picture of the apple will be sharper and more distinctly an apple.

So the more megapixels you have, the better your resolution and a better, sharper picture.

Answer 4

Try this instead. I think it will explain it to you much better. And as far as picture taking...the more pixels, the better.

Answer 5

More is better. Very clear.
