SCREEN NOT CLEAR FOR ME
Tested in Linux with VLC : - a rotation 180° must be set - the resolution of the video window is 640x480. Zooming for more magnification is possible in that window. With the Windows driver (tested win7.exe in XP SP3), the resolution is 640x480, even in the Picture mode. A higher resolution for a still picture is not available. Note : The rotating knob is used for a pre-focusing, difficult to adjust. The optimum distance for the automatic focusing seems to be 5.5 cm from the lens.
