H04N 19/177 - Methods or arrangements for coding, decoding, compressing or decompressing digital video signals using adaptive coding characterised by the coding unit, i.e. the structural portion or semantic portion of the video signal being the object or the subject of the adaptive coding the unit being a group of pictures [GOP]
This technology relates to a coding device and a coding method with which the amount of information related to information identifying reference images can be reduced. A coding unit uses reference images to generate prediction images. In cases when an image to be coded is an image other than the first image in a group of pictures (GOP), a transmission unit transmits "inter_ref_pic_set_prediction_flag" indicating that reference-image-identification information, which identifies a reference image, for an image anterior in coding order to the image to be coded is to be used as the reference-image-identification information for the image to be coded. This technology is applicable to coding devices or the like for the high efficiency video coding (HEVC) format.

The present invention relates to an image processing device and method enabling noise removal to be performed according to images and bit rates. A low-pass filter setting unit 93 sets, from filter coefficients stored in a built-in filter coefficient memory 94, a filter coefficient corresponding to intra prediction mode information and a quantization parameter. A neighboring image setting unit 81 uses the filter coefficient set by the low-pass filter setting unit 93 to subject neighboring pixel values of a current block from frame memory 72 to filtering processing. A prediction image generating unit 82 performs intra prediction using the neighboring pixel values subjected to filtering processing, from the neighboring image setting unit 81, and generates a prediction image. The present invention can be applied to an image encoding device which encodes with the H.264/AVC format, for example.
