Test pattern
[Check item]
This test pattern is intended to judge whether or not the electronic RDH board is abnormal.
There are two test patterns which correspond to the 8-bit mode in which the electronic RDH is not used, and
the mode in which it is used, respectively. The test pattern checks the state of the electronic RDH board. If
an abnormality is found when an electronic RDH is used with several copies of the test pattern output, there is
an abnormality in the electronic RDH. In this case, an abnormality in the test pattern excludes any difference
in error dispersion.
