WIPO Patent Application WO/2019/202986
Kind Code:
An objective of the present invention is to provide an image generation technique with which it is possible to alleviate unnaturalness associated with image quality fluctuation resulting from movement of an observer's viewpoint. Provided is an image generation device comprising: an image generation part for generating a pseudo-viewpoint image IΦk and a pseudo-viewpoint image I-Φk using a disparity derivation edge DΦk for which the phase difference to a viewpoint image I is Φk (where Φk (1≤k≤K) is a real number satisfying 0<Φ1<…<ΦK≤π/2); and an output image generation part for converting a sequence, in which a pseudo-viewpoint image IΦ0 (corresponding to the viewpoint image I) and the pseudo-viewpoint images IΦk, I-Φk (0≤k≤K) are arranged in the order IΦK, IΦ(K-1), …, IΦ1, IΦ0 (=I), I-Φ1, …, I-ΦK, into I(1), I(2), …, I(K), I(K+1), I(K+2), …, I(2K+1) so as to obtain a pseudo-viewpoint image I(m) (1≤m≤2K+1), and generating an output image Outm (1≤m≤2K-1) from the pseudo-viewpoint image I(m). The output image Outm and an output image Outm+1 (1≤m≤2K-2) include phase modulation components that offset each other when the images are viewed in composite.
