    Abstract: The present disclosure relates to an image processing device and a method capable of suppressing the reduction of an image quality due to encoding/decoding. The image processing device includes: a quantization unit that when orthogonal transform processing is skipped with respect to a current block, quantizes all components of the current block using one weighting coefficient and when the orthogonal transform processing is performed on the current block, quantizes each component of the current block using a quantization matrix; an encoding unit that encodes the coefficient of the current block which is quantized by the quantization unit; and a transmission unit that transmits the coded data of the current block which is obtained by being encoded by the encoding unit. The present disclosure can be applied to, for example, an image processing device.

    Abstract: The present technology relates to a decoding device and a decoding method capable of reducing the amount of information relating to information specifying a reference image. A reception unit receives inter_ref_pic_set_prediction_flag representing whether reference image specifying information specifying a reference image, which is used for generating a predicted image, of a prior image that is an image prior to a current coding image in coding order that is transmitted in a case where the current coding image is an image other than a first image of a GOP (Group of Picture) is used as the reference image specifying information of the current coding image. The present technology, for example, can be applied to a decoding device of an HEVC (High Efficiency Video Coding) system.

    Abstract: An image processing device and method capable of suppressing block noise.
    A β LUT_input calculation unit and a clipping unit calculate β LUT_input that is a value input to an existing β generation unit and an extended β generation unit. When the value of β LUT_input qp from the clipping unit is equal to or less than 51, the existing β generation unit calculates β using the LUT defined in the HEVC method and supplies the calculated β to a filtering determination unit. When the value of β LUT_input qp from the clipping unit is larger than 51, the extended β generation unit calculates extended β and supplies the calculated β to the filtering determination unit. The device can be applied to an image processing device, for example.

    Abstract: An image processing apparatus including an inter-prediction section that generates a set of reference pixels of fractional pixel positions from a reference image for motion compensation and searches an image to be encoded for a motion vector by using the set of generated reference pixels and an encoding section that encodes the image to be encoded on a basis of a result of searching for the motion vector by the inter-prediction section. The inter-prediction section includes a reference pixel at a fractional pixel position further inward than a first predetermined distance from a boundary of a partial region corresponding to a slice or a tile, in the set of reference pixels that are used for searching the partial region for a motion vector.

    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 and method capable of suppressing a decrease in subjective image quality. A size of a current block for a prediction process is set according to a size of a peripheral block situated on a periphery of the current block. The prediction process is to generate a predicted image of an image to be encoded. An intra prediction process is performed on the current block that has been set and the predicted image is generated. The image to be encoded is encoded using the predicted image that has been generated. The present disclosure can be applied to, for example, an image processing device, an image encoding device, or an image decoding device.
