On several occasions I have had discussions with individuals regarding camera quality. There are two elements regarding quality, subjective and objective quality. Obviously each individual can look at the image produced and make up there own mind. In some cases it is helpful to have some objective data to help elucidate the individuals assumptions. To that end I posted a simple test.
Simply choose a typical resolution and click the test button. The video that you see show up in the application is not to scale, it is 1/3 scale. The key element is the frame per second metric and the capture size. Not all cameras will support all of these resolutions so you may notice that the capture size is not the same as the resolution that you selected. You should use a browser other than Chrome. In other words Firefox, IE, etc… The reason I say this is that Google decided to write their own Flash player that does not act the same as the Adobe Flash player. As an example if you run this test in Chrome and select a resolution that is not supported by your webcam you will not see the resolution change but if you run this using the Adobe Flash player and choose a resolution that is not supported by your webcam you will see the resolution that is supported. This is a pretty cool ability because you can see what resolutions are supported by your webcam.
