In any case, the microcontroller searches the image in ram from the bottom up. When it finds an appropriate edge, it marks the x and y location. It measures the x and y distance of this edge from the center of the image. It then issues a corrective movement command to the servos, which respond by redirecting the camera, until the object is centered in the view. Here are my results thus far.
Camera is difficult to open with a normal flathead screwdriver, but it can be done.
I didn't have the three-bladed miniature screwdriver that would have matched the screws used. By the way, I went ahead and cut a hole in the back of the ball, so the cable could exit in a place where it would not interfere with mounting the camera on a pan-tilt base. Pinout Before Removing Connector Numbers above refer to pin number on the M64282FP chip. I wire-wrapped the circuit board that you see here. The schematic shows the components I used.
