2. Connect the white balance adjustment jig (luminance meter).
[Adjustment procedure]
Adjustment gradations values (IN) are shown on Page 9, and adjustment
initial values (OUT), on Pages 10 and 11, respectively. For white balance
adjustment, adjust the OUT values shown on Pages 10 and 11.
Set the specified gradation for point 6, and adjust RGB to the reference
values of point 6.
Set the specified gradation for point 1. Set G of point 1 to the default value
[(adjusted G value of point 6)/896, with fractions rounded] and adjust RB to
the reference values of point 1.
Set the specified gradation for point 2. Set G of point 2 to the default value
[(adjusted G value of point 6)/896, with fractions rounded] and adjust RB to
the reference values of point 2.
Set the specified gradation to point 3. Set G of point 3 to the default value
[(adjusted G value of point 6)/896, with fractions rounded] and adjust RB to
the reference values of point 3.
Set the specified gradation to point 4. Set G of point 4 to the default value
[(adjusted G value of point 6)/896, with fractions rounded] and adjust RB to
the reference values of point 4.
Set the specified gradation to point 5. Set G of point 5 to the default value
[(adjusted G value of point 6)/896, with fractions rounded] and adjust RB to
the reference values of point 5.
