• The CCD (Charged Coupled Device) generates three analog video signals.
• The SBU (Sensor Board Unit) converts the three analog signals to 10-bit digital
signals. It sends these signals to the IPU (Image Processing Unit).
• The IPU processes the image, then the image data is sent to the controller.
