Abstract: The present invention relates to an image processing device and method which enable encoding efficiency in intra prediction to be improved.In the event that the optimal intra prediction mode is mode 0, adjacent pixels to be used for prediction of the current block are pixels A0, A1, A2, and A3. According to these pixels and a 6-tap FIR filter, pixels a−0.5, a+0.5, and so on with ½ pixel precision are generated, and further, pixels a−0.75, a−0.25, a+0.25, and a+0.75 with ¼ pixel precision are generated by linear interpolation. Subsequently, the optimal shift amount is determined with a value of −0.75 through +0.75 that is phase difference between an integer pixel and generated fractional pixel precision serving as a candidate of the shift amount in the horizontal direction. The present invention may be applied to an image encoding device which performs encoding using the H.264/AVC system, for example.

Abstract: A motion compensating unit performs motion compensation in decoding of a current layer and a first compressing unit compresses a motion vector of the current layer that is reconstructed by the motion compensating unit and used for the motion compensation in decoding of another layer. Alternatively, a motion predicting/compensating unit performs motion prediction and compensation in encoding of a current layer and a first compressing unit compresses a motion vector of the current layer that is generated by the motion predicting/compensating unit and used in the motion prediction and compensation in encoding of another layer. An image processing device and method utilizing the units can suppress an increase in a storage capacity necessary for encoding and decoding.

Abstract: The present technology relates to an encoding device, an encoding method, a decoding device, and a decoding method that enable sign data hiding processing to be appropriately performed. An orthogonal transform unit orthogonally transforms a difference between an image to be encoded and a prediction image to generate orthogonal transform coefficients. A sign hiding encoding unit applies, based on a sum of absolute values of non-zero orthogonal transform coefficients of the orthogonal transform coefficients generated by the orthogonal transform unit, sign data hiding processing of deleting a sign of a head non-zero orthogonal transform coefficient, and correcting the non-zero orthogonal transform coefficients such that a parity of the sum of absolute values of non-zero orthogonal transform coefficients becomes a parity corresponding to the sign, to the orthogonal transform coefficients. The present technology can be applied to an encoding device, for example.

Abstract: The present disclosure relates to image processing devices and methods that can increase encoding efficiency in encoding or decoding motion vectors in cases where an input is an interlaced signal. The current PU and the reference PU to be referenced by the motion vector information about the current PU belong to top fields. Meanwhile, a Co-located PU belongs to a top field, and the reference PU to be referenced by the motion vector information about the Co-located PU belongs to a bottom field. Therefore, there is phase shifting between the fields. In view of this, a parity adjustment unit performs −½ shift adjustment on the vertical component of the motion vector information about the Co-located PU as indicated by the arrow with a dashed line. The present disclosure can be applied to image processing devices, for example.
