It is a nasty marketing trick. You have 1.3X MP camera and every pixel has three sub-pixels (red, green, blue). So the total amount of (sub)pixels is: 3 x 1.3X ~= 5MP.

Another trick is that the higher "resolution" - understand the size of image - is artificially increased using an interpolation.

If you need a real 5MP resolution you need a 5MP camera, not 1.3MP, there is no way, how to cheat it.

Hi!

As I said before, the last webcam I bought was useless it was not Linux fault.

I went to the Steren Shop and they changed it to me for another webcam, this time

the COM-105 one, wich uses other USB Driver and works perfectly with Cheese

by just plugging it. 

The cam also works with my Windows 7 VM very well, but I have a New problem:

In the webcam features, it says the cam has a 5MP resolution interpolated, but in

the instructions it says the cam has a 1.3 MP Resolution, wich is really poor for what

I wanna do.

¿How can I reach that 5MP Resolution in Linux? ¿What does that mean? 

¿Does this webcam can really record a 5MP Video? ¿How can I do it?

Thanks!

P.S. No matter I use Cheese or the Webcam's recording software for Windows,

the resolution is very very poor :(
