Abstract: An image processing apparatus and a method capable of reducing an amount of codes in encoding or decoding. A type setting unit uses a deblocked pixel value to set a type of a filter which is common between components of Y, Cb, Cr in units of LCUs, and provides the type to a syntax write unit. An offset setting unit uses a deblocked pixel value to set an offset independent for each of components of Y, Cb, Cr in units of LCUs. An SAO control information setting unit provides the offset or a merge flag, which is set by referring to the offset given by the offset setting unit, to the syntax write unit. The present disclosure can be applied to, for example, an image processing apparatus.

Abstract: The present invention relates to image processing device and method which can suppress block noise. A filter strength determination unit determines the filter strength for every four lines under the control of a control unit. In other words, if a block boundary determination unit has determined to perform filtering, the filter strength determination unit determines at which strength of the strong filter or the weak filter the filtering process is performed, and outputs the determination result to a filter calculation unit. On this occasion, the filter strength determination unit uses the Bs value in the determination formula of the strong filter. For example, in the case of using the Bs value, the threshold of the determination is set in accordance with a linear function of the Bs value from the control unit. The present disclosure can be applied to, for example, an image processing device.

Abstract: There is provided an image processing device including circuitry configured to predict, from an image of a first layer, an image of a second layer having a different pixel attribute from the first layer, by using a lookup table in which a combination of a luma component, a first chroma component, and a second chroma component of the first layer is mapped to a predicted pixel value of the second layer corresponding to the combination, wherein a predicted value of a luma component of the second layer is acquired by using a first lookup table, and a predicted value of a first chroma component of the second layer is acquired by using a second lookup table with granularity different from granularity of the first lookup table.

Abstract: High efficiency video coding (HEVC) enhancements are described for intra-block copying for reducing motion vector (MV) coding redundancy and enhancing in range extensions (RExt) by selecting a default block my predictor. In reducing MV data redundancy, the value of MVx and/or MVy can have a baseline at the width (W), or height (H) of the respective block, whereby fewer bits need to be encoded. One embodiment for enhancing RExt provides an improved selection of a default block vector predictor for the first CU performing intra-block copying in a CTU.
