摘要： 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.

摘要： 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.

摘要： The present invention relates to an image processing apparatus and method in which an increase in the amount of encoding can be suppressed while realizing high-performance motion compensation.In step S1, a motion vector corresponding to the difference between the coordinates of an encoding target block and the coordinates of a reference block is calculated. In step S2, a horizontal-direction fine adjustment filter Hh is generated. In step S3, a vertical-direction fine adjustment filter Hv is generated. In step S4, the pixel values of the reference block is finely adjusted by applying the horizontal-direction and vertical-direction fine adjustment filters Hh and Hv to the reference block. The reference block is then assigned to the encoding target block, thereby generating a motion-compensated prediction image. In step S5, the difference signal between the pixel values of the encoding target image and the pixel values of the prediction image is calculated, and is subjected to orthogonal transform and quantization. The resulting difference signal is then encoded. Meanwhile, the integer-precision motion vector is also encoded. The present invention is applicable to an image encoding apparatus for compression-encoding moving images and to an image decoding apparatus for decoding the encoded moving images.

摘要： The present technology relates to an encoding device and an encoding method, and a decoding device and a decoding method that are capable of reducing the calculation amount of orthogonal transform processing or inverse orthogonal transform processing. A DWT unit (91) performs a DWT of which the calculation amount is smaller than that of a KLT for residual information. KLT units (92-0 to 92-8) perform separable-type KLTs for a low-frequency component of the residual information that is acquired as a result of the DWT using bases of KLTs of the corresponding intra prediction modes. A coefficient acquired as a result of the KLT and a high-frequency component of the residual information that is acquired as a result of the DWT are losslessly encoded. The present technology can be applied to, for example, an image encoding device.

摘要： The present invention relates to an image processing device and method whereby deterioration of effects of filter processing due to local control of filter processing when encoding or decoding can be suppressed. A boundary control flag generating unit 132 of a control information generating unit 112 generates boundary control flags based on system specification information which a system specification managing unit 141 manages. A control unit 171 of an adaptive filter processing unit 113 determines a processing method for filter processing to be performed as to pixels nearby a slice boundary following the value of the boundary control flag. For example, selection is made to perform filter processing straddling slices or to perform filter processing closed at the present slice. The present invention can be applied to an image processing device, for example.

摘要： The present invention relates to an image processing device, an image processing method, and a program that can reduce processing loads and delays while suppressing decreases in inter prediction precision when motion compensation operations with fractional precision are performed in inter predictions. When a pixel of a predicted image in an inter prediction has a fractional pixel position that is not a ½ pixel position in the horizontal direction and the vertical direction in a reference image, a reference image read unit 41 reads predetermined reference pixels including reference pixels aligned in two oblique directions perpendicular to each other. A FIR filter 42 calculates a pixel in a fractional position in the reference image as the pixel of the predicted image, by using the read predetermined reference pixels. The present invention can be applied to encoding devices that perform compression encoding by H.264/AVC, for example.
