Flicker Filter Coefficient Low (2C)
Flicker Filter Coefficient High (2D)
Register
2D, 2C
Range: {0:[21]}
Filter Coefficients: FLK/64, 1-FLK/32, FLK/64
Example: FLK = 10 hex; 16 decimal; for a ¼, ½, ¼, three line average flicker filter.
Note: If FLK is set to a value greater than 21, then the weight factor applied to the lines above and below
the current line are greater than the current line creating a double line effect. Therefore, values > 21 are
not recommended as they will create visual artifacts, but the FS400 does not prohibit these settings.

Flicker Filter Coefficient bits [4:0] The Flicker Filter Coefficient
combines with the Sharpness Coefficient to provide a wide range
of edge enhancement and detail vs. flicker. The Flicker Filter
Coefficient controls the width and height of the edge
enhancement (impulse function). Flicker Filter has an implicit
denominator of 16.
