Abstract:
To achieve a reduction in the amount of coding taken in the use of an asymmetric partition and to implement efficient encoding/decoding processes exploiting the characteristics of the asymmetric partition. In a case that a CU information decoding unit decodes information for specifying an asymmetric partition (AMP; Asymmetric Motion Partition) as a partition type, an arithmetic decoding unit is configured to decode binary values by switching between arithmetic decoding that uses contexts and arithmetic decoding that does not use contexts in accordance with the position of the binary values.

Claim (Index 3):
An image encoding device for encoding an image for each coding unit to generate an encoded image data, the image encoding device comprising:\n an arithmetic encoding circuitry that encodes a binary sequence specified by using a cording unit size and a partition mode of the cording unit; and a prediction image generation circuitry that generates a prediction image using the partition type of the cording unit, wherein the arithmetic encoding circuitry encodes one of each binary in the binary sequence by using an arithmetic encoding process that uses contexts, and encodes the other of the each binary in the binary sequence by using a bypass encoding process, in a case that (i) the coding unit is predicted by an inter prediction, (ii) the cording unit size is greater than 8\u00d78, and (iii) the partition type of the cording unit indicates an Asymmetric Motion Partition mode, wherein the binary sequence includes at least a first binary and a second binary, wherein (i) the first binary indicates the partition type is a symmetric partition type or an asymmetric partition type, and (ii) the second binary indicates a positional relationship between a smaller partition and a larger partition of the asymmetric partition, the arithmetic encoding circuitry encodes the binary sequence corresponding to the partition types of the cording unit indicating 2N\u00d72N type or N\u00d7N type by using the arithmetic encoding process that uses contexts, in a case that (i) the coding unit is predicted by an intra prediction and (ii) the cording unit size is equal to 8\u00d78, and the arithmetic encoding circuitry encodes the binary sequence corresponding to the partition types of the cording unit indicating one of 2N\u00d72N type, 2N\u00d7N type and N\u00d72N type by using the arithmetic encoding process that uses contexts, in a case that (i) the coding unit is predicted by the inter prediction and (ii) the cording unit size is equal to 8\u00d78.
