Absurd
Newbie level 1

Hi.
I understand that optic pc-mouses take successive images of the surface they move on, and compare them in order to identify relative movement.
For example, suppose the following are two pictures captured from optical mouse one after another:

(The pixelized part represents the surface, and the brown image is the picture taken)
The mouse will then report "3 left 1 down".
Now, I want to find out in what rate does my mouse take pictures, where can I find this information?
I looked at the specifications page here and couldn't find anything related.
Any help would be greatly appreciated.
