There are not much control options because it is only a quick test
script for opencv with a camera i hacked in a few hours. ;)
I updated the script on pastebin with english help for the key bindings.
You could just select the color of the grid, some additional grid lines
and the blob detection.
The scaling just doesn't show the 0 in the left down corner. Also a
quick hack and it doesn't work very well with different resolutions. The
hard coded resolutions on keys 1,2,3,4 are for my camera model. Maybe
you have to change them for yours in the code.
Because my usb microscope camera has a manual focus ring i didn't care
about controlling the focus. So i think if the camera doesn't do it
natively the program will not change it at all. ;)
Ciao,
Rainer
