"Mega-" is generally the prefix applied to a unit of measure, to multiply that unit by one million. Therefore a Megapixel is 1,000,000 pixels.
Edit: there are exactly 1,048,576 pixels in 1 megapixel !
Mega = 1 million.
MegaPixel means 1,000,000 pixels. You probably haven't phrased your question in a manner to get a better answer.
5 mega pixels for the Ipod touch 4g.
yup, a megapixel is one million pixels. Eg. an eighteen point one megapixel camera can take a photo which is made up of 18100000 single colored dots called pixels.
1,048,576 pixels
one megapixel is a million pixels, so 9.2 mega pixels would be 9.2 million pixels, or 9,200,000 pixels.
Megapixels are the count of how many pixels there are, which determines the "graunlarity" of photos.
There are 1 million pixels in 1 megapixel so 1200pixels is 0.0012 megapixels.
Megapixel is like megabite. Megabite has 1 000 000 bytes so megapixel has 1000 000 pixels. Mega refers to 10^6
It's got a simple 2 megapixel camera.
It depends on the resolution. For example a resolution of 1220x960 would have 1,171,200 pixels or 1.1 megapixel. You take the height (1220) times the length (960.) If referring to an image, you can say it is a 1220 by 960 or a 1.1 megapixel image.
it has 3 million pixels
D1 is video resolution. D1 is 720x480 pixels (NTSC) or 720x576 pixels (PAL). The D1 resolution corresponds to a maximum of 414,720 pixels or 0.4 megapixel.
