1.6 Digital Section Adjustment and Standard Data Generation
Before doing the digital section adjustments, the light source and color chart
characteristics must be measured and saved in the personal computer.
Required standard data:
•
CMOS white balance data (WhiteBalanceRef.wb)
•
Color matrix chart data (MatrixChart.pos)
•
Color matrix adjustment data (ColorMatrixRef.mat)
* The name of the file in the Reference folder is in parentheses.
These data are saved within Reference in the folder where the adjustment
software is installed. Be sure to make a back-up copy of these data.
CMOS White Balance Basic Data
The CMOS white balance adjustment is for fixing the irregular output caused by
the CMOS's color. As explained below, use a known-good camera to measure the
light source's characteristics and filter characteristics.

Required tools
•
Light source (EF8000, 5000)
•
C12 filter

Adjustment procedure:
1) Attach an EF 50mm f/1.8 lens to the known-good camera and connect the
camera to the computer. Start up the digital section adjustment software.
2) Select "CMOS white balance adjustment."
3) Select "Basic data generation."
4) Set the light source (EF8000, 5000) to LV 12. Set the lens to manual focus and
infinity.
5) After everything is set, click "Set completed."
6) Attach a C12 filter to the lens, and click "Set completed."
7) Attach another C12 filter (total 2 filters) to the lens, and click "Set completed."
The CMOS white balance data's basic data can now be generated. Click "Check
standard data" to check the data. Jot down this data on a piece of paper.

This procedure must be done before the digital section adjustment.
(Especially, generating this standard data is very important. If it is
not generated, the correct color reproduction will not occur.)
Do the regular maintenance (data generation). (This is not
necessary each time you do the adjustment. However, be sure to do
it when the light source bulb has been replaced or the location has
been changed.
A known-good camera is required for a data generation.
A standard data will be stored in the Reference folder where the
adjustment software has been installed. It is recommended to back
up the data, because it will be deleted when the adjustment
software is deleted or updated.
