    Abstract: A buffer device stores, in relation to a first area and a second area, which are partial areas respectively located on an identical line of an encoding target frame, and a third area, which is a partial area on the line below the identical line, reference image data for each search range of a reference frame that is referred to during motion search processing executed in order of the first area, the second area, and the third area, the buffer device including a memory for storing the reference image data, and a buffer control unit which, when the motion search processing is executed on the second area, executes control so that among the reference image data included in a first search range that is referred to during the motion search processing of the first area, the reference image data included in a third search range that is referred to during the motion search processing of the third area are left in the memory without being deleted.

    IPC: G06T9/40

    Abstract: An encoding device includes a division unit that acquires three-dimensional data representing positions of a plurality of points distributed along a surface of an object in a three-dimensional space and divides a parent space including the points in the three-dimensional space into a plurality of child spaces and an encoding unit that changes, based on a position of a target space, which is the child space, to which a sign representing whether the points are included is allocated, according to whether the points are included in a first child space adjacent to the target space, processing for allocating the sign to the target space and a second child space adjacent to the target space.

    Abstract: A coding device executes coding having divided an image into blocks, and includes: a candidate obtainment unit that obtains a plurality of provisional motion vector candidates in a coding target block; an evaluation information obtainment unit that obtains a correspondence vector that is a vector having a same direction and a same magnitude as a direction and a magnitude of the obtained provisional motion vector candidates, and evaluation information of a search center indicated by the correspondence vector in a coded block; and a selection unit that, on the basis of the evaluation information, selects, from the plurality of provisional motion vector candidates, a number of motion vector candidates that is lower than the number of the plurality of provisional motion vector candidates.
