Can you tell me definitively what the resolution of the camera on the JD Robot is? Information online suggests it is 640x480, but when first connecting in EZ-Builder the resolution defaults to 320x240. This can be changed to 640x480 with the connection controls, but I do not really see any difference in the image when it is increased. Also, if the camera is set to 640x480 then face detection completely stops working (and the main reason I wanted the higher resolution was in an attempt to improve the distance at which the face detection would potentially work). Any advice / info would be appreciated.
