摘要

There is provided a technique that includes a triangle merging candidate list constructor structured to construct a triangle merging candidate list including spatial merging candidates, a first triangle merging candidate selector structured to select, from the triangle merging candidate list, a first triangle merging candidate that is uni-prediction, and a second triangle merging candidate selector structured to select, from the triangle merging candidate list, a second triangle merging candidate that is uni-prediction, in which in a region where motion compensation by weighted averaging by the first triangle merging candidate and the second triangle merging candidate is performed, uni-prediction motion information of one of the first triangle merging candidate or the second triangle merging candidate is saved.

說明書

Moreover, a display unit that displays a picture decoded by the picture decoding device may be added, as a display device, to the configuration. In that case, the display unit reads out a decoded picture signal constructed by the decoded picture signal superimposer 207 and stored in the decoded picture memory 208, and displays the signal on the screen.

Moreover, an imaging unit may be added to the configuration so as to function as an imaging device by inputting a captured picture to the picture coding device. In that case, the imaging unit inputs the captured picture signal to the block split unit 101.

FIG. 37 illustrates an example of a hardware configuration of the coding-decoding device according to the present embodiment. The coding-decoding device includes the configurations of the picture coding device and the picture decoding device according to the embodiments of the present invention. A coding-decoding device 9000 includes a CPU 9001, a codec IC 9002, an I/O interface 9003, memory 9004, an optical disk drive 9005, a network interface 9006, and a video interface 9009, in which individual units are connected by a bus 9010.
