Flicker Filter Sharpness [4-0].
SHP accentuates the joint high
vertical - high horizontal frequencies to sharpen edges. SHP is an
unsigned number.
Range:
{0 : 31} Provides 0 to 31/16 (6 dB) joint high horizontal and vertical frequency boost.

Flicker Filter Coefficient [4:0].
Provides weighting factor for 3
line flicker filter. FLK is an unsigned number.
Range:
{0 : 23}
Notes:
The FS450 Flicker Filter is more complex than a Three Line Average (TLA) flicker filter. The FS450 flicker filter
includes a variable vertical filter response in addition to a sharpness function. Adjusting the FLK Coefficient
modifies the vertical filter from no filtering (FLK = 0) to a Three Line Average (FLK = 16), giving the user the best
choice in filtering options.
In addition to the variable vertical settings, the FS450 flicker filter has a sharpness function. This function is a two
dimensional peaking function which accentuates the joint high vertical - high horizontal spatial frequencies (an
"edge enhancer"). The three line variable two dimensional flicker filter is formed by summing the unit impulse
function with a vertical flicker function scaled by FLK (Flicker Coefficient) and the peaking function which is scaled
by SHP (Sharpness Coefficient). The FLK and SHP variables have 5 bits of resolutions, with a usable a range
from 0 to 16/16 for FLK, and 0 to 31/16 for SHP.
