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: The quantization parameters (QP) for Chroma are extended up to and more preferably to the same range as Luma QP (e.g., 0 to 51). Previous, values of Chroma QP only extended up to 39. Techniques are provided for determining extended Chroma QP values (e.g., for Cr and Cb) based on the Luma QP and picture level chroma offsets. In one preferred embodiment, slice level offsets are added making the method particularly well-suited for slice level parallel processing. The extension of Chroma QP enhances functionality, flexibility and friendliness of the High Efficiency Video Coding (HEVC) standard for various applications.

Abstract: The buffer management methods simplify the complexity of STD buffer management for HEVC and make is easy to implement HEVC in deployed AVC/MPEG-2 networks (as legacy re-multiplexers are able to be used for re-purposing HEVC content). The buffers for base and enhancement layers are also be managed independently before re-assembly and this simplifies the STD model. Re-assembly is still implemented before decoding an enhanced HEVC video stream.

An encoding unit generates a predicted image using a reference image.

The present technology, for example, can be applied to an encoding device of an HEVC (High Efficiency Video Coding) system.

Abstract: The present disclosure relates to an image processing apparatus and an image processing method capable of improving processing efficiency with pipeline processing in encoding or decoding of a motion vector. In a motion vector encoding unit, such configuration is adopted that when a spatial prediction motion vector is derived according to AMVP or Merge mode, the use of a motion vector of a PU adjacent to a top right of a PU in question is prohibited. Therefore, the motion vector encoding unit performs encoding processing of a motion vector by using only motion vector information of B1, B2 which are PUs located at Top with respect to the PU in question and A0, A1 which are PUs located at Left with respect to the PU in question. The present disclosure can be applied to, for example, an image processing apparatus.
