# Sensor Vertical Flip Example
#
# This example shows off vertically flipping the image in hardware
# from the camera sensor.

import csi
import time

csi0 = csi.CSI()
csi0.reset()  # Reset and initialize the sensor.
csi0.pixformat(csi.RGB565)  # Set pixel format to RGB565 (or GRAYSCALE)
csi0.framesize(csi.QVGA)  # Set frame size to QVGA (320x240)
csi0.snapshot(time=2000)  # Wait for settings take effect.
clock = time.clock()  # Create a clock object to track the FPS.

# Change this to False to undo the flip.
csi0.vflip(True)

while True:
    clock.tick()  # Update the FPS clock.
    img = csi0.snapshot()  # Take a picture and return the image.
    print(clock.fps())  # Note: OpenMV Cam runs about half as fast when connected
    # to the IDE. The FPS should increase once disconnected.
