Maxrunner said:so wouldnt that make it less precise when aiming?not talking about the other capabilities. I've read that the wiimote had an infrared camera with high resolution. Or did i read wrong?... i think it was that oriental guy who made those awsome demos using the wiimote...he said something about the wiimote having a hi-res(1024x780 or something) infrared camera
I think people mightn't be happy comparing the two here, but the native resolution I believe is 128x96 on the wiimote camera. The image is resized up to 1024x768 for processing.
Of course, because the camera is on the controller, the resolution is all 'dedicated' to what it's orientated at, so it's not really comparable apples-to-apples with the resolution of a camera observing a controller.
In any case, I think the Sony motion controller is perhaps more reliant on colour resolution than on image resolution for this. I think they may use the RGB intensities, compared against a known rgb intensity model of the sphere, to calculate the centre of the sphere at a sub pixel level. They're not looking at the pixels and going 'oh, the centre of the sphere is at this pixel'.
