Computer Vision
Vision is the main sense of our hobby robot.
We use J2ME-enable cell phone as a brain for our small robot and it is
very understandable why do we use cell phone camera as a sensor.
No need to connect additional cameras, no need to use special hardware connections, etc.
Cell phones have ready to be used J2ME procedures to work with embedded camera.
Theoretically it would be good to work with video stream data in real-time,
but practically it is impossible.
In reality we should do one snapshot, then wait, then do image analysis and then do action.
Taking pictures is pretty heavy job for cell phone CPU.
You can see this effect, when you manually do snapshots using your phone.
First you press snapshot button, then your hear sound, then you see delay
(on some phones you can see moving disk or something like this) then the picture is saved.
I suppose that the time delay needed for reading image conversion it to JPEG format.
