Abstract
Apparatus and method for forming an interpolated image corresponding to a given temporal distance ratio between a first and a second image including respectively, a first image in which the first and second images include a first and a second 3-D shape model of an object having respective shading values and that there is a 3-D motion vector defining the transformation between the first and the second 3-D shape models. The method includes: a) adjusting the interpolation 3-D motion vector (Vab) to obtain an interpolation 3-D motion vector (vi); b) forming an interpolation 3-D shape model (Mi) from the interpolation 3-D motion vector (Vi) and either the first or the second 3-D shape model (Ma,Mb); and c) forming an interpolation image from the interpolation 3-D shape model and the image shaping values from the first and second 3-D shape models. The invention provides a method and apparatus for frame interpolation of a moving image which remedies block-shaped distortion in interpolated frames, and which can reproduce smooth movement even when the input image includes movement in 3-dimensional space.
