TEST PICTURES FOR COLOR ALIGNMENT
Basic concepts about color alignment
To evaluate colors properly, a correct reference is
needed. In professional terminology, it is named as
'White Balance'. By adjusting the White Balance we can
obtain a correct reference (i.e. daylight) for the color
alignment.
The ACTAS uses a window pattern (a white square in
the middle of a black screen) as the "Test picture" to
adjust the Low Level White Balance and the High Level
White Balance. The "Gain" adjustment is used for the
High Level White Balance and the "Cut-off" for the Low
Level White Balance.
There are 6 other test pictures used to examine the
results: the pluge, the vertical bar, the horizontal bar, the
gamma, the blocks and the corners.
