1.
Output a white balance pattern.
2.
Check that the color temperature is “cool”.
3.
Set to factory mode, WB-ADJ.
4.
Set “R-CUT” “G-CUT” “B-CUT” 80h.
5.
Attach the sensor of color analyzer to the center of highlight window.
6.
Fix G drive at C0h and adjust “B-DRV” and “R-DRV” so x, y value of color analyzer
become the “Color temperature High” in table 1.
7.
Increase RGB together so the maximum drive value in RGB becomes FCh. That is, set
“ALL DRIVE” to FCh.
8.
Set color temperature to “Normal”.
9.
Set “R-CUT” “G-CUT” “B-CUT” 80h.
10. Attach the sensor of color analyzer to the center of highlight window.
11. Fix G drive at C0h and adjust “B-DRV” and “R-DRV” so x, y value of color analyzer
become the “Color temperature Mid” in table 1.
12. Increase RGB together so the maximum drive value in RGB becomes FCh. That is, set
“ALL DRIVE” to FCh.
* When WB-ADJ(mid) is adjusted by data-offset, set values as follows.
R-DRV : the same as R-DRV_cool
G-DRV : “G-DRV_cool” -2hDAC
B-DRV : “B-DRV_cool” -22hDAC
13. Set color temperature to “Warm”.
14. Set “R-CUT” “G-CUT” “B-CUT” 80h.
15. Attach the sensor of color analyzer to the center of highlight window.
16. Fix G drive at C0h and adjust “B-DRV” and “R-DRV so x, y value of color analyzer
become the “Color temperature Low” in table 1.
17. Increase RGB together so the maximum drive value in RGB becomes FCh. That is, set
“ALL DRIVE” to FCh.
* When WB-ADJ(warm) is adjusted by data-offset, set values as follows.
R-DRV : the same as R-DRV_cool
G-DRV : “G-DRV_cool” -AhDAC
B-DRV : “B-DRV_cool” -62hDAC
18. Set color temperature to “Cool”.
19. Copy values adjusted by HD pattern to the NTSC data area of EEPROM.
