| Summary: | A cross-color/dot interference reduction circuit according to one embodiment of the present invention includes a signal generation unit configured to calculate a difference in an input signal between adjacent frames and generate a difference signal, a component extraction unit configured to extract a cross-color/dot interference component from the difference signal, a combination output unit configured to combine an interference reduction signal corresponding to the cross-color/dot interference-component with the input signal and provide an output signal with a reduced cross-color/dot interference, an image scene analysis unit configured to analyze an image scene contained in the input signal, and a signal amplification/attenuation unit configured to amplify/attenuate the interference reduction signal based on an image scene analysis result from the image scene analysis unit. |
