Abstract:
1. A method of rendering multiple views for a multi-view display device, the multi-view display device having a number of subsets of light generating elements located in a first plane and optical directory elements associated with the light generating elements that overlay the light generating elements in the first plane of a display screen for displaying respective multiple views of a multi-view image in mutually different directions relative to the multi-view display device, the method comprising: computing, via a motion estimation device, a first motion vector field for a first time instance on basis of (i) a first input image of a time sequence of input images and (ii) a second input image of the time sequence of input images; computing, via an interpolation device, a sequence of first motion compensated intermediate images on basis of (i) the first motion vector field, (ii) the first input image and/or (iii) the second input image; and providing, via a driver device, respective pixel values of the sequence of first motion compensated intermediate images to first subsets of light generating elements of the display screen, wherein an output of each subset of light generating elements renders one of the respective multiple views displayed in the mutually different directions which together form a first multi-view image; the method further comprising: providing, via the driver device, the sequence of first motion compensated intermediate images to second subsets of light generating elements of the display screen after a predetermined delay, wherein one or more image of the sequence of first motion compensated intermediate images is reused in creating and displaying a consecutive second multi-view image, and wherein creating the consecutive second multi-view image includes (a) computing a sequence of new motion compensated intermediate images and (b) remapping the one or more image of the sequence of first motion compensated intermediate images as used for the first multi-view image to create respective multiple views of the consecutive second multi-view image, further wherein a particular reused driving image, which includes the reused one or more image of the sequence of first motion compensated intermediate images, is shifted by a configurable view shift VS(i), i=index, from a first view in the first multi-view image to a second view in the consecutive second multi-view image, which is adjacent to the first view; and the method further comprising: computing, via a processor, for each of the first and second multi-view image, a value of temporal distance TDD(i), Temporal Distance Driving, between adjacent driving images provided to the light generating elements of the display screen for a multi-view image with index i, wherein the computed value of temporal distance TDD(i) is used in mapping driving images to create respective views in a corresponding sequence of driving images for each respective first and second multi-view image, wherein the computed value of temporal distance TDD(i) is based on estimated motion in the time sequence of input images.
