An efficient encoding / decoding process that reduces the size of encoded images when using asymmetric partitioning and takes advantage of the properties of asymmetric partitioning is implemented. An image decoding device that is provided with a motion-compensation parameter derivation unit that derives a motion-compensation parameter that indicates a prediction scheme, namely either unidirectional or bidirectional prediction. If the size of prediction units is less than or equal to a prescribed size, the motion-compensation parameter derivation unit switches prediction schemes for the derivation of the motion-compensation parameter.

Disclosed is an image encoding device that aims to increase encoding efficiency and to increase mode estimation accuracy using the characteristics of transformation coefficients. In response to an assessment value calculated on the basis of the characteristics of transformation coefficients, the range of estimated modes and selectable modes is limited, a mode that minimizes encoding cost is selected from among predetermined modes within the limited range of modes, when the number of the aforementioned limited modes is one, a flag for mode identification is not encoded, and when there are a plurality of modes, the aforementioned selected mode is encoded. As a result, the amount of encoding cost of the mode-identifying flag is decreased and encoding can be performed with a high encoding efficiency, mode estimation accuracy is increased, and furthermore, the amount of flag encoding is decreased and encoding efficiency is increased.

In the disclosed multi-view image encoding / decoding method in which a frame to be encoded / decoded is divided and encoding / decoding is done to each region, first, a prediction image is generated not only for the region to be processed, but also for the already encoded / decoded regions neighboring to the region to be processed. The prediction image is generated using the same prediction method for both kinds of regions. Next, correction parameters for correcting illumination and color mismatches are estimated from the prediction image and decoded image of the neighboring regions. At this time, the estimated correction parameters can be obtained even at the decoding side, therefore, encoding them is unnecessary. Thus, by using the estimated correction parameters to correct the predicted image that was generated for the region to be processed, a corrected predicted image that can be actually used is generated.
