Abstract
Determining whether AC component prediction is effective or not based on the sum of absolute values of unpredicted AC components (&Sgr;mS ) before calculating prediction error S in the AC components. If &Sgr;mS is smaller than a predetermined threshold &thgr; , it is determined that the prediction will be ineffective. In this case, the unpredicted AC components are encoded directly without calculating the prediction error S.
