    摘要： The present invention relates to an image processing apparatus and a method and a program that enable an amount of code to be suppressed below a desired value with more reliability. An emergency mode determining section 142 determines that the amount of code of a next picture is likely to exceed an upper limit if a target bit calculated by a rate controlling section 118 exceeds a predetermined upper limit. If it is determined that the amount of code of the next picture is likely to exceed the upper limit, the code amount controlling section 142 controls an orthogonal transducing section 114 to replace a transform coefficient of a predetermined frequency component with zero, controls an intra predicting section 125 to restrict intra prediction modes to be applied, and controls a mode determining section 127 to restrict inter prediction modes to be applied. The prevent invention can be applied to an encoding apparatus.

    摘要： The present invention is directed to an image information encoding apparatus, 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 delivers information of picture type of frame Picture_type to a picture type discrimination unit. The picture type discrimination unit transmits command to a motion prediction/compensation unit on the basis of that information. The motion prediction/compensation unit 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 P picture on the basis of that command.
