Hello, the zoom factor in most cases, just skip reading some pixels but they are still sensed out by the camera. So the same overall duration is normal with such a method. Specially for 480xX, the full resolution is used but with windowing. additionally requiring 480 pixel on a line with a zoom

Hello Giles, I did the time measurments for both microcontroler acquisition and bluetooth comunication to the PC. For the BT transmission duration, I've noticed that the more lines I extracted, the more bytes I had to transmit, so the transmision time increased as expected. For the microcontrole
