Embodiment approach 1

[0029] The image processing device of this embodiment can be applied to image display devices such as TV (television), PC (Personal Computer), smartphone, digital photo frame, etc., in which viewers can view stereoscopic images with naked eyes. A stereoscopic image refers to an image including a plurality of parallax images having mutual parallax. In addition, the images described in the embodiments may be still images or moving images.

[0030] figure 1 It is a schematic diagram of the image display device 10 of this embodiment. The image display device 10 includes a display device 14 and an image processing device 12 .

[0031] The display device 14 displays stereoscopic images. The display device 14 adopts, for example, a 3D display method such as an integral imaging method (II method), a multi-eye method, or the like.

[0032] The display device 14 includes a display panel 20 and a light beam control unit 22 . The display panel 20 is in the first direction (for exampl...

Embodiment approach 2

[0107] In Embodiment 1, it was described that the parallax image acquired by the first acquisition unit 30 is corrected so that the pixels of the parallax image of the first parallax number to be observed are observed in each region P on the display device 14 . And a case where a stereoscopic image is generated from the corrected parallax image after correction.

[0108] In this embodiment, a case will be described in which a parallax image is corrected based on the first parallax number and the luminance distribution corresponding to the positional relationship between the viewpoint position and each region P. FIG.

[0109] In addition, the luminance distribution represents the angular distribution of the luminance of light rays emitted from each region P of the display device 14 . The angle represents, for example, an angle in the first direction (left-right direction) or an angle in the second direction (vertical direction). In this embodiment, the case where the angle is ...

no. 3 Embodiment approach

[0204] Regarding the image processing device according to the present embodiment, in the image processing device 12A in the second embodiment, correction using a filter coefficient (luminance filter) corresponding to the luminance distribution is performed. As a result, the screen can be turned into a normal visual area with a small processing cost.

[0205] The filter coefficient refers to transforming the parallax image (specifically, In other words, the coefficient of the pixel group y(i, j)) of each region P before correction. Hereinafter, points different from the previous embodiment will be described.

[0206] Figure 18 It is a block diagram showing the image processing device 12B of the image display device 10B. The image processing device 12 further includes a second generation unit 46 and a fourth storage unit 44 . In addition, the third storage unit 43 and the first storage unit 34 are connected to the second generation unit 46 . In addition, a correction unit ...

Abstract

In an embodiment, an image processing device includes: a first acquiring unit that acquires a plurality of parallax images having parallax between one another; a second acquiring unit that acquires identification information of a parallax image to be observed from a predetermined observing point position in each of a plurality of regions into which a display area on which three-dimensional image is configured to be displayed is divided, each of the regions including at least one element image, and the element image including each pixel in the plurality of parallax images; a corrector that corrects pixels at positions corresponding to the regions in the parallax images into pixels of parallax images identified by the identification information; and a first generator that generates the three-dimensional image from the parallax images resulting from the correction.

Description

[0001] (Citation of related applications such as priority basic application) [0002] This application is based on Japanese Patent Application No. 2011-280468 (filing date: December 21, 2011), and priority is claimed from this application. This application, by reference to this application, includes the entire content of this application. technical field [0003] Embodiments of the present invention relate to an image processing device and method, and an image display device. Background technique [0004] There are image display devices that allow viewers to view stereoscopic images. In an image display device, a light control unit for controlling the emission direction of light from each pixel is provided on the front surface of a display panel in which a plurality of pixels are arranged, and a plurality of parallax images having mutual parallax are displayed. [0005] For example, in the case where the display area itself can be bent like a curtain or a display, or when ...
