Embodiment 1

[0053] will refer to Figure 1A and 1B The configuration of the image generating device for generating virtual viewpoint images related to Embodiment 1 will be described. Figure 1A and 1B Each of these is a block diagram illustrating the configuration of the image generating device 100 related to the present embodiment.

[0054] Such as Figure 1A As shown, the image generation device 100 includes a difference image generation unit 101 , a difference image correction unit 102 , a pixel shift processing unit 103 and an unfixed pixel area interpolation unit 104 . The image generation device 100 generates and outputs a virtual viewpoint image signal 4002 using the virtual camera parameter 7000 , the depth image signal 2000 and the two-dimensional image signal 1000 . Here, the two-dimensional image signal 1000 is a signal of an image captured with a camera at a viewpoint in a three-dimensional space. The virtual camera parameters 7000 are provided for defining a virtual camera ...

Embodiment 2

[0078] will refer to Figure 6 The configuration of the image generating device 200 related to the second embodiment will be described. Figure 6 is a block diagram illustrating the configuration of the image generating device 200 related to the present embodiment.

[0079] Such as Figure 6 As shown, the image generation device 200 includes a difference image generation unit 101 , a pixel shift processing unit 103 , an interpolation unit 104 in an unfixed pixel area, and a noise elimination unit 105 in an unfixed pixel area.

[0080] Similar to Embodiment 1, the image generation device 200 generates a virtual viewpoint image signal 4002 by using the two-dimensional image signal 1000 and the depth image signal 2000 with low accuracy, but performs noise removal in the unfixed pixel region instead of the The described difference image is corrected to prevent the image quality degradation of the virtual viewpoint image signal 4002 .

[0081] Hereafter, reference will be made to ...

Embodiment 3

[0100] will refer to Figure 11 The structure of the image generating device 300 related to the third embodiment will be described. Figure 11 is a block diagram illustrating the configuration of the image generation device 300 related to the present embodiment. and Figure 1A and 1B The same structural elements will be due to Figure 1A and 1B The same reference numerals are designated and descriptions thereof will be omitted.

[0101] Such as Figure 11 As shown, similar to Embodiment 1, the image generation device 300 includes a difference image generation unit 101 ′, a difference image correction unit 102 , a pixel displacement processing unit 103 and an unfixed pixel region interpolation unit 104 . Although Embodiment 1 provides a two-dimensional image signal 1000 , a corresponding depth image signal 2000 and a virtual camera parameter 7000 as input, this embodiment provides multiple two-dimensional image signals 1000 as input.

[0102] Such as Figure 11 As shown, ...

Abstract

Provided are an image generation apparatus, three-dimensional image display apparatus, image generation method and non-transitory computer readable medium. An image generation apparatus for generating a virtual-viewpoint image, includes a disparity-image-generating section which generates a disparity image corresponding to a two-dimensional image, by using a depth image and a parameter of a virtual camera; a disparity-image-correcting section which corrects the disparity image based on contour lines extracted from the two-dimensional image and the disparity image, or corrects the depth image to be used for generating the disparity image based on contour lines extracted from the two-dimensional image and the depth image; an pixel-shift-processing section which shifts each pixel of the two-dimensional image according to the corrected disparity image, to generate an intermediate image; and a unfixed-pixel-area-interpolating section which interpolates unfixed pixels to which the shifted pixels have been assigned in the intermediate image, to generate the virtual-viewpoint image.

Description

technical field [0001] The present invention relates to an image generating device, an image display device, an image generating method, and a non-transitory computer-readable medium storing an image generating program. In particular, the present invention relates to an image generating device, an image display device, an image generating method, and a non-transitory computer-readable medium storing an image generating program, each of which is provided for a signal based on a two-dimensional image and a signal of a difference image Generate or display stereoscopic images. Background technique [0002] Recently, techniques for creating 3D display contents are attracting more and more attention corresponding to technological development of 3D image display devices. When a 3D image display device receives an image signal through a transmission line and performs 3D display, it is necessary to transmit an image signal corresponding to each viewpoint to the device. In particula...
