Block diagrams of the cameras
The following diagrams illustrate the data flow and the bit resolution of
image data after being read from the CCD sensor chip in the camera. The indi-
vidual blocks are described in more detail in the following paragraphs. For
sensor data see Chapter

14 bit
Setting LUT = OFF effectively makes full use of the 14 bit by bypassing the
LUT circuitry; setting LUT = ON means that the most significant 12 bit of the
14 bit are used and further down converted to 10 bit.
