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

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.

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