Re: Another Question About Webcams in F13

Monday, 1 November 2010

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 :(
