hi,
i have SE k700. on the back it is written "VGA 4.1 mm 1:2.8"
and how is this different from a mega pixel camera.
can any body help me out what does it means???
thanx!!!

VGA is 0.3 megapixel

a picture is composed of a collection of dots called
pixels. pixels determine the size of the picture, and the more pixels a camera can generate, the bigger the picture will be. the k700 has a VGA camera, it stands for
0.3 megapixels, or million pixels. it is derived by multiplying the maximum height and width of the picture (640x480 = 307,200 pixels, or 0.3 mega pixels).

300,000 effective pixels, as in K750/W800/W810 it is 2,000,000 effective pixels O_O!!! Now for 10 megapixels it is 10,000,000!!!! sorry lol.

thanx,
but it also hav a extendable picture size of 1280x960.!!!
how this happens thru a VGA camera??

software in the phone mathematically interpolates the pixels actually taken in the picture to make more pixels where it thinks they should/would be

@ajeetpv: thanks for making the question. I always wanted to know that.
@masseur: thanks for replying.
I love this page

as masseur have said, the 1280x960 option on the K700 is the interpolated picture.
interpolation (by definition in the web) is the increase of image resolution by the addition of new pixels throughout the image, the colors of which are based on neighboring pixels. that way, you'll get a bigger picture at the expense of sacrificing quality. the camera of the K700 is designed to have a maximum output of 640x480 pixels (also known as VGA), but the 1280x960 option works like this: it captures the picture as 640x480, then resizes the picture twice its size (hence the 1280x960 pixels). that's why you may notice that in the 1280x960 mode of the K700, it takes a few seconds processing and saving the picture than in the 640x480 mode.
and as for the topic question, 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...
whew! it may sound too technical for some, but i hope that answers the question about pixels in camera phones...
