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: The present technique relates to an image processing apparatus and an image processing method capable of suppressing deterioration in accuracy of a predicted image and reducing the number of storable reference images. A motion prediction/compensation unit generates a predicted image of an encoding target image by using a reference image. A frame memory is, for example, a decoded picture buffer (DPB) and preferentially stores the reference image of which display order is close to that of the encoding target image. The present technique may be applied to, for example, an encoding device using a high efficiency video coding (HEVC) scheme.

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.
