VP3 to 0
This sets the correction signal output start position in the vertical direction. The number of line counted from
the front edge of the VST pulse at which vertical arithmetic processing of the correction signal starts is set. The
correction data for the initial line is output continuously only for the number of lines set by VP.
VINT4 to 0
This sets the arithmetic processing interval for vertical correction. Vertical correction arithmetic processing is
performed every number of lines set by VINT. Normally set arithmetic processing for each line (VINT = 1).
ANM5 to 0
This sets the correction point interval in the vertical direction. There are 13 vertical correction points with
respect to the actual panel display area switching, so this sets the number of lines at which correction points
are spaced for the internal arithmetic processing.
Example) To use the full correction point data in the vertical direction, set the correction point interval ANM as
follows.
SVGA panels:
ANM = 600 ÷ 12 = 50 (110010)
XGA panels:
ANM = 76 ÷ 12 = 64 (000000)
1/A6 to 0
This sets the inverse of ANM. Set the 6th to 12th digits below the decimal point in binary format with 7 bits.
Linear interpolation with an accuracy of 1 bit is performed using this setting value.
Example) ANM = 50:
1/50 (decimal) = 0.000001010010 (binary)
Set the 6th to 12th digits.
Example) ANM = 64:
1/64 (decimal) = 0.000001000000 (binary)
Set the 6th to 12th digits.
