high quality 2megapixels CMOS sensor interpolated to 6megapixels..
guys what does it mean? im using Hp cam b4 but right now, I bought a AOSTA brand which is cheaper but have a good quality pics than to my other cam..can anyone explain this to me, about interpolation? thanks

INterpolation means that the camera basically guesses at what data might lie between the actually-recorded pixels. All cameras do intoerpolation to some degree, but interpolating a 2Mpx image to 6Mpx is a bit severe. You can never create data that doesn't exist, so the images from such interpolation are always quite "soft", that is, not sharp.

i've never noticed the pics from my camera being soft and it interpolates from 3mp to 6mp.

Fuji is kind of unique in their interpolation. Their sensors instead of being [] squares, are actually more like honeycomb shaped. The camera then rotates the octogon, The end result is more data from less pixels. Pretty smart technology.

Ahhh... There re some 3 layer sensors out that detect 2 MP for EACH color (RBG). Hence 6MP. They are three layers but only ONE sensor detecting 2 MP (PER color) so they are 2MP cams that really do 6MP... Fuji is very different than this. Interestingly enough, Fuji seens to be moving away from the SUPER CCD tech now.
Sorry can't find the link to the article about the newer sensor technology....
Here is the latest news from FujiSuperCCD |

| I think the links above are good. Quite simply - interpolation = guessing. |

Interpolation is defining the value of an intermediate point by applying a formula to known values on either side of that point. Photoshop (pre-CS) alone has three different methods of calculating those intermediary values (Bi-cubic is supposed to be the most accurate). For our purposes, it is essentially the same as resampling/upsampling an image to a larger size ...
Making an image smaller (downsampling) uses a similar but usually more accurate method of averaging pixel values into new intermediates, and almost always gives a more satisfactory result than enlarging. |

| If there is a way to turn off interpolation on your camera, you can _usually_ do a much better job enlargening photos on your own. |
