Figure 6-37 Camera demo running on MAX 10 NEEK board
A Five-fingers touch function is implemented in this demonstration to stop LCD from refreshing the
camera image. This is achieved by stopping the input of Frame Buffer VIP and the image retrieved
by the Clock Video Output VIP from the Frame Buffer VIP is always the same. The camera image
can start refreshing again by a single-finger touch to enable the input of Frame Buffer VIP.
The zoom-in and zoom-out gestures with two fingers are implemented to control the display active
readout window on the image sensor.
Auto-focus function is triggered by single-finger touch.
