Row and column counter
: Pixel values are based on a counter which increments on
every pixel in a line. Out of a 16-bit pixel value, the 8 most significant bits show the
line number and the 8 least significant bits show the column number in that line.
Each test pattern value can be made to move cyclically through the image stream by
enabling by using
Test pattern control
– Moving
.
•
Solid value
: The fixed pixel value sweeps through the entire 9-bit range, with each
frame still consisting entirely of one pixel value.
•
X gradient:
The normal gradient moves horizontally from right to left.
•
Y gradient:
The normal gradient moves vertically from bottom to top.
•
X xor Y gradient
: The normal gradient shifts diagonally from the bottom right to the
top left corner.
•
Row and column counter:
The normal row counter moves vertically from bottom to
top and the normal column counter moves horizontally from right to left.
Test pattern control
– Shift
allows you to shift all 9-bit pixel values from the generator by the
specified number of bits.
