6.5 IMAGE PROCESSING
6.5.1 OVERVIEW
The CCD generates an analog video signal. The SBU (Sensor Board Unit) converts the
analog signal to an 8-bit digital signal, then it sends the digital signal to the IPU (Image
Processing Unit) board.
The IPU board performs the image processing, such as auto shading, filtering,
magnification, gradation processing.
The ASIC on the controller board performs the image editing, such as image repeat, double
copy.
Finally, the IPU board sends the video data to the LD drive board.
