    • In a picture information coding device for outputting picture compression information based on an AVC encoding scheme, optimum reference relationships in a GOP structure including hierarchical B pictures can be obtained and random access from an I picture that is not an instantaneous decoding refresh picture can be performed.When multiple-frame prediction is performed, with a memory management control operation command generation unit (13), a reference B picture that exists between a picture and a P picture or I picture is registered as a long-term reference picture using a memory management control operation command to manage a picture in a decoded picture buffer. The reference B picture is placed as the first in a reference picture list using a reference picture list reordering command when a B picture that exists between the P picture or I picture and the reference B picture is processed. The long-term reference picture in the decoded picture buffer is set to be a non-reference picture by setting the maximum value of a long-term frame index to [0] using a memory management control operation command when the P picture or I picture is processed. Random access from the I picture that is not an instantaneous decoding refresh picture is performed.

    • The present invention relates to an image processing apparatus, an image processing method, and a program capable of increasing the quality of a predicted image generated through inter prediction even when a motion compensation process with integer-pel accuracy is performed.A computing unit 115 decodes a transform coefficient subjected to inverse orthogonal transform and supplied from an inverse orthogonal transform unit 114 by adding the transform coefficient to an inter predicted image supplied from a switch 214. A motion prediction/compensation unit 212 performs motion compensation on the decoded image. An FIR filter 213 performs a filter process on the motion-compensated image using a filter coefficient corresponding to a compressed image and transmitted from an image encoding apparatus. The filter coefficient is obtained using the least-square method when the compressed image is generated. The FIR filter 213 supplies the filtered image to the switch 214 as the inter predicted image. The present invention is applicable to an image decoding apparatus that performs decoding using, for example, the H.264/AVC standard.

    • The present invention relates to an image processing apparatus and method in which, in a case where an AIF is employed in motion compensation, the number of calculations for motion vectors is restricted, whereby the load of encoding processing can be reduced.In step S11, a motion vector calculator selects one of the calculated filter coefficients stored in a memory. In step S12, the motion vector calculator calculates a motion vector of each macroblock of an encoding target image by using interpolation pixels which are interpolated with a fraction precision by an AIR using the selected calculated filter coefficient. In step S13, the motion vector calculator calculates the filter coefficient for the encoding target image by using the calculated motion vector so that the prediction error becomes minimum. The calculated filter coefficient is supplied to the memory and is stored therein, and is used for calculating the motion vector for the subsequent image. The present invention can be applied to an image encoding apparatus.
