Problems solved by technology

Moreover, sometimes there may be a situation in which multiple viewers do not change positions during audiovisual viewing, but it is recognized that at least one viewer is moving based on the image captured by the above-mentioned camera, thereby switching the stereoscopic image.
At this time, switching of stereoscopic images is a problem for viewers who are identified as being outside the moving viewer

[0016] exist figure 1 A stereoscopic image display device based on the first embodiment is shown in . The stereoscopic image display device 1 of this embodiment is a naked-eye stereoscopic image display device, and includes a display device 10 for displaying an image, and a camera 20 for detecting the position of a viewer from a captured image. The display device 10 has a display screen in which pixels are arranged in a matrix. The camera 20 is provided, for example, in the lower frame of the frame surrounding the display screen of the display device 10 .

[0017] Furthermore, the coordinate system XYZ is set in the stereoscopic image display device of the present embodiment. For example, with the position of the camera 20 as the origin, the plane parallel to the display screen of the display device 10 as the X-Y plane, the Z-axis is set to be perpendicular to the X-Y plane and the direction toward the audience 100 is the positive direction, thus setting Coordinate system X...

[0034] Next, a stereoscopic image display device according to the second embodiment will be described. In the stereoscopic image display device of the second embodiment, in the first embodiment, the face tracking unit 30 samples, and the memory 35 creates and stores a histogram from the sampled data. This histogram can be created, for example, as follows. For example, the space of the coordinate system XYZ set in the first embodiment is divided into 1 cm 3 unit, determine which unit is included in the viewer’s position (x, y, z) sampled and detected by the face tracking unit 30, by calculating the number of sampled data included in the unit, and storing in the memory 35, so that Create a histogram. That is to say, the memory 35 has a three-dimensional array M (i, j, k) (i, j, k=0, 1, 2, ...), each array corresponds to each unit, and the number of sample data contained in each unit The numbers are stored in the corresponding arrays.

Abstract

A stereoscopic image display apparatus according to an embodiment includes: a display device including a display panel including pixels, and an optical plate controlling light rays emitted from pixels; a camera provided in the display device; a face tracking unit making a decision whether a viewer exists in front of the display device based on an image picked up by the camera, and if the viewer exists, sampling and detecting a distance from the display device to the viewer and a position of the viewer; a memory storing the position of the viewer sampled and detected by the face tracking unit; and an image display control unit estimating the position of the viewer based on the position of the viewer stored in the memory and driving and controlling the display panel on based on the estimated position, when the face tracking unit does not recognize that the viewer exists.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from Japanese Patent Application No. 2011-189484 filed on August 31, 2011, the entire contents of which are hereby incorporated by reference. technical field [0003] Embodiments of the present invention relate to a stereoscopic image display device. Background technique [0004] In the naked-eye type stereoscopic image display device, a viewer (user) can watch a stereoscopic image with naked eyes without using special glasses. In such a stereoscopic image display device, a plurality of images of different viewpoints are displayed on a flat display device (for example, a liquid crystal display device), relying on light control elements such as a parallax barrier (parallax barrier) and a lenticular lens (lenticular lens). Take control so that viewers can view stereoscopic images. The light control element is usually arranged on the front of the flat panel display device...
