FRAME INTERPOLATION DEVICE, FRAME INTERPOLATION METHOD, AND RECORDING MEDIUM

摘要

According to one embodiment, a frame interpolation device includes a motion vector interpolation unit that assigns interpolated motion vectors calculated based on motion vectors indicating motions of an image between frames and a temporal position of an interpolated frame inserted between the two frames to the interpolated frame per unit region, a motion-compensated image generation unit that generates a forward motion-compensated image and a backward motion-compensated image based on the interpolated motion vectors, and an interpolated frame generation unit that generates the interpolated frame by averaging corresponding regions of the forward motion-compensated image and the backward motion-compensated image by different weights between a normal region in which one or one pair of interpolated motion vectors is assigned per unit region and a non-normal region which is configured of at least one of a collided region and a vacant region.

1. A frame interpolation device comprising:
a motion vector interpolation unit that, based on motion vectors indicating motions of an image between two frames and a temporal position of an interpolated frame inserted between the two frames, calculates interpolated motion vectors indicating motions of images between the interpolated frame and the two frames, and assigns the calculated interpolated motion vectors to the interpolated frame per unit region; a motion-compensated image generation unit that generates a forward motion-compensated image generated based on image information on the forward frame out of the two frames and the interpolated motion vectors, and a backward motion-compensated image generated based on image information on the backward frame out of the two frames and the interpolated motion vectors; and an interpolated frame generation unit that generates the interpolated frame by averaging corresponding regions of the forward motion-compensated image and the backward motion-compensated image by different weights between a normal region in which one or one pair of interpolated motion vectors is assigned per unit region and a non-normal region which is configured of at least one of a collided region assigned with a plurality or a plurality of pairs of interpolated motion vectors per unit region and a vacant region assigned with no interpolated motion vector.
