Method and/or apparatus for cross-color and cross-luminance suppression using shimmer detection

A method for post-separation comb filtering using shimmer detection, comprising the steps of:

• (A) generating a delay of one or more frame periods in response to a format of an input signal;
• (B) determining which pixel locations is said input signal exhibit an oscillation pattern based on component values of said pixel locations;
• (C) generating a control signal in response to said delays from step (A) and said input signal;
• (D) calculating an average signal in response to said input signal and a first of said delays from step (A);
• and
• (E) presenting (i) said input signal when said control signal is in a first state and (ii) said average signal when said control signal is in a second state.

An apparatus comprising:

• means for generating one or more delays for one or more frame periods in response to a format of an input signal;
• means for determining which pixel locations in said input signal exhibit an oscillation pattern based on component values of said pixel locations;
• means for generating a control signal in response to said input signal and said delays;
• means for calculating an average signal in response to said input signal and a first of said delays of one or more frame periods;
• and
• means for presenting (i) said input signals when said control signal is in a first state and (ii) said average signal when said control signal is in a second state.
