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
      register in order to determine the referential W/B of the panel with a DVI input, which
      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.
