The present invention is directed to an image information encoding apparatus ( 10 ) used, in receiving compressed image information through network media, when processing of such compressed image information is performed on storage media. A picture sorting buffer ( 12 ) delivers information of picture type of frame Picture_type to a picture type discrimination unit ( 22 ). The picture type discrimination unit ( 22 ) transmits command to a motion prediction/compensation unit ( 21 ) on the basis of that information. The motion prediction/compensation unit ( 21 ) generates predictive picture by using filter coefficients having the number of taps lesser than that of P picture with respect to B picture for which operation quantity and the number of memory accesses are required to more degree as compared to, e.g., P picture on the basis of that command.
