The video output of the RCA on the "CMUcam4" offers a great way to control (like a "debug" function). To do this, you will connect to a monitor or TV to NTSC (not included). To facilitate your development we offer a small LCD (optional) ideally designed for this function. More info about the LCD here. Once the "CMUcam4" board is powered on, it will display a welcome screen (allowing you to ensure proper functioning of the whole setup).
At this point, you have the option of following a manipulation on the two buttons of "CMUcam4" board and then enter "Test" mode. In this mode, the deck "CMUcam4" will analyze and store the color of the object that you present and then keep track of it. Also a rectangle of the perimeter of the object is to provide further guidance. If you place the "CMUcam4" on a pan and tilt device, it will ensure to always move towards the colored object that you have initially shown.
If you remove the colored object, a message appears on the screen to tell you that no color similar to that stored is present in front of the camera lens.
