Problems solved by technology

[0006] However, in the conventional technique, since it is necessary to repeat the operation of changing the panel parameter → performing a display reflecting the change of the panel parameter → observation in a cyclical manner; therefore, it takes a long period of time to perform calibration

[0023] figure 1 is an overview diagram showing the stereoscopic image display device 1 according to the embodiment. The stereoscopic image display device 1 includes a display unit 10 and an image processing unit 20 .

[0024] The display unit 10 is a device capable of displaying a stereoscopic image including a plurality of parallax images having different parallax from each other. Such as figure 1 As shown, the display unit 10 includes a display element 11 and a beam control element 12 .

[0025] The parallax images constitute a stereoscopic image and are used to enable an observer to view the stereoscopic image. In the stereoscopic image, the pixels of each parallax image are allocated in such a way that when the display element 11 is viewed from the viewpoint position of the observer by means of the light beam control element 12, one eye of the observer sees a specific parallax image, and the observer's The other eye sees another parallax image. That is, a stereoscopic...

[0094] Compared with the first embodiment, the second embodiment is different in the way of arranging the correction unit, which performs correction for each sub-pixel in order to set the parallax number observed from the viewpoint position as the third parallax number using the correction data , the correction data indicates the difference between the fourth parallax number and the third parallax number, the fourth parallax number represents when the panel parameter changes from the first panel parameter Θ 0 Change to the panel parameter Θ selected by the selection unit 25 a , the disparity image observed from the viewpoint position is expected. A detailed explanation is given below. Meanwhile, regarding the same points as those of the first embodiment, explanations will not be repeated.

[0095] Figure 11 is a block diagram showing a structural example of the image processing unit 200 according to the second embodiment. Such as Figure 11 As shown, the image processing...

Abstract

According to an embodiment, an image processing device includes a first obtaining unit, a specifying unit, a first calculator, a second obtaining unit, and a selector. The first obtaining unit obtains a first parallax number representing a parallax image that is actually observed. The specifying unit specifies a panel parameter candidate. The first calculator calculates a second parallax number which represents a parallax image to be observed from the viewpoint position when the panel parameter is changed from the first panel parameter to the panel parameter candidate. The second obtaining unit obtains a third parallax number calculated when a first panel parameter candidate is specified, and the third parallax number is smaller than an error between the second parallax number calculated when a second panel parameter candidate is specified, and the third parallax number, the selector selects the first panel parameter candidate as the panel parameter.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims the benefit of priority from Japanese Patent Application No. 2012-199759 filed September 11, 2012; the entire contents of which are incorporated herein by reference. technical field [0003] The embodiments described herein generally relate to an image processing apparatus, an image processing method, and a stereoscopic display device. Background technique [0004] In the glasses-free 3D panel (glasses-free three-dimensional display device), light beam control elements with linear optical apertures such as cylindrical lenses or barriers (slits) arranged in a circular manner in the horizontal direction are arranged in such as liquid crystal In front of the display element of the panel, for stereoscopic viewing with the naked eye; the positional relationship between the display element and the light beam steering element is of considerable importance. This positional relationship ...
