Assuming the 3 bit input pattern that represents this 50% duty cycle grayscale is 0x3 (or
011b), the values in
up-table.

Since all patterns must be evaluated against their specific use, no more examples for half
intensity will be offered. Instead, another example will be used to make a walking distortion
more obvious.
Take the example of a one-third luminous intensity grayscale pattern. Assume a 3Hx3Vx3F
matrix for this definition. Wanting the intensity to be evenly distributed and given the three
frame interval, any cell in the matrix should only be active for one frame. The matrix could be
filled in as in
