2-2 WHITE Balance Coordinates

2-2-1 White Balance Adjustment

1. W/B Adjustment is required for the following four modes: DVI → DTV → PC → CVBS(VIDEO)

→ CVBS(VIDEO PIP)

2. Adjustment Method (DVI, DTV, PC : VG828, CVBS : Adjust RF signals to match the Toshiba pattern (in-house signal)

! Adjust the target set by adjusting the panel logic and the video DNIe adjustment register in

is the full digital path.

@ For DTV adjustment, adjust the adjustment register of ad9888 to align the DTV signal

to the DNIe and logic panel value which was fixed with a DVI adjustment so that they are in effect considered to be the same signals. (At this time, do not adjust the gain of

AD9888

→ the Highlight W/B does not need to be adjusted since its deviation falls

within valid distribution range.)

# PC adjustment is same as DTV adjustment. (The offset can be applied to the values

obtained through DTV adjustment. However, additional adjustment is required for Y, Cb, and Cr of DTV since PC processes R, G, and B signals.)

$ cvbs adjustment is performed with the Toshiba pattern (in-house signal) and differs

from the VG828 signals in the above three modes. Hence, it should be performed with the same method of ! DVI adjustment.

% Finally, activate PIP in video mode, and repeat W/B adjustment.

❈ Thus, Micom saves the W/B data separately for each memory mode of the block

(See the block diagram given below) during W/B adjustment.

Micom can memorize the four modes separately. However, under the current adjustment guidelines, DTV and PC are memorized with the same value during DVI adjustment and CVBS is memorized with a separate value.
