Abstract

Official abstract text for this publication.

An image processing device includes an estimator, a first calculator, a selector, a determination module, and a third calculator. The estimator estimates a motion vector to reference images of an input video from a target pixel of a process target image. The first calculator calculates candidate pixel values corresponding to positions in the reference images. The selector selects a motion vector for which the error is small as many as the number smaller than the number of motion vectors acquired for the target pixel. The determination module determines the candidate pixel values corresponding to the selected motion vectors. The third calculator calculates a pixel value after correction of the target pixel from an arithmetic average or a weighted sum of the candidate pixel value determined equal to or less than the reference and the pixel value of the target pixel.

First claim

Opening claim text (preview).

What is claimed is: 1. An image processing device, comprising: an estimator configured to estimate a motion vector to a plurality of reference images of an input video from a target pixel of a process target image of the input video, for each reference image, wherein the plurality of reference images include pre-display reference images to be displayed before the process target image and post-display reference images to be displayed after the process target image; a first cal…
