14 VP-790 Blending Images - Warp Adjustment
Note that in the example in Figure 15 , the size and shape of the squares are not
even across the whole screen. The linearity needs adjustment.
Linearity is achieved by adjusting the center positions as indicated in Figure 16 .
Note the relative sizes of the red rectangles, these should be equal sizes. If they are
not equal as in the example below the linearity will be poor.
Figure 16: Adjusting the Linearity
Continue the adjustment looking to achieve an even size of test pattern squares
across the whole screen and the overlapping area as closely aligned as possible.
When the Green and Magenta Test pattern lines are correctly over-laid, their
combined colors turn white (see
Figure 17 ).
Increase the number of nodes to give a more detailed adjustment
only when you have made all the adjustments you can with the
coarse setting.
