20 Configuring the Camera
The built-in auto black level control adds tiny positive or negative voltages to both Vtop and
Vbottom to compensate black level changes due to temperature. Auto black level does not change
the overall system gain.

The look-up table (LUT) control, shown in Figure 19, allows you to change two knee point values.

Enter X1, Y1, X2, Y2 values directly to adjust the knee curve. In the integrated camera software,
the look-up table cannot be controlled interactively. The Table Selection pull-down menu allows
you to select the Linear or Gamma 45 option. This control also allows you to check the positive or
negative image option.
3.4.7 Memory Pages
All the camera parameters such as shutter mode, shutter speed, gain, offset level, scan mode, and
LUT can be saved into seven (7) available memory pages on the EEPROM in the camera. The pages
are numbered 0-6. The Load Page button loads the corresponding camera settings from the EEPROM
while the write page button writes the current camera settings to the corresponding memory page
in the EEPROM.
Page 1, shown in Figure 20, is the power-up default page. Page 0 is the factory default. To save your
current camera settings for power up default, write the settings to memory page 1.
