METHOD AND DEVICE FOR FRAME INTERPOLATION OF A MOVING IMAGE

摘要

A method of forming an interpolated image corresponding to a given temporal dist ance ratio between a first and a second image comprising, respectively, a first image is described in which the first an d second images include a first and a second 3-D shape model of an object having respective shading values and that there is a 3D motion vector defining the transformation between the first and the second 3-D shape models. The method comprises: a) adj usting 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 se cond 3-D shape models. The invention aims to provide a method and device for frame interpolation of a moving image which reme dies block-shaped distortion in interpolated frames, and which can reproduce smooth movement even when the input image includ es movement in 3-dimensional space. Apparatus is also described for carrying out the above method.
