Difference between VGA and Mega Pixel camera

VGA differs from a mega pixel by picture size. as we all know by now, VGA stands for a picture that's sized at 640x480 pixels. multiply those two, and you get 307,200 pixels (or 0.3 mega pixels). mega stands for million so a mega pixel means a million pixels. for example, a camera that can generate a picture size of 1280x960 without the use of interpolation can generate 1,228,800 pixels, or 1.2 megapixels; they just round it off to make it 1.3 mega pixels. some phones like that are the S700i, W550i, and the K600. camera phones like the K750i, W800i, and the W900i can generate pictures with a size of 1632x1224 (again without interpolation), hence producing 1,997,568 pixels, or 1.9 megapixels. again, they just round it off to make it 2.0 mega pixels...
