Hi, sorry for the delay on this:

import sensor

import image

sensor.reset() # Reset and initialize the sensor.
sensor.set_pixformat(sensor.RGB565) # Set pixel format to RGB565 (or GRAYSCALE)
sensor.set_framesize(sensor.QVGA) # Set frame size to QVGA (320x240)
#sensor.skip_frames(time=2000) # Wait for settings take effect.
clock = time.clock() # Create a clock object to track the FPS.

print("")

def print_reg(reg):
    print("[0x%02x]=0x%02x" % (reg, sensor.__read_reg(reg)))

while True:
    clock.tick() # Update the FPS clock.
    img = sensor.snapshot()
    #print(clock.fps()) # Note: OpenMV Cam runs about half as fast when connected
    # to the IDE. The FPS should increase once disconnected.

```

Please let me know if this improves performance to a point where it works for you.

I can commit this officially if it’s good.
