Patent number: 6362753Abstract: Determining whether AC component prediction is effective or not based on the sum of absolute values of unpredicted AC components (&Sgr;mS0) before calculating prediction error S in the AC components. If &Sgr;mS0 is smaller than a predetermined threshold &thgr;1, 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.Type: GrantFiled: August 16, 2000Date of Patent: March 26, 2002Assignee: Casio Computer Co., Ltd.Inventor: Tsuyoshi Kasahara
