Problems solved by technology

[0004] However, regardless of whether an HMD is used, stereoscopic 3D displays using binocular parallax are known to have problems in that the observer may feel unnatural and experience great eye fatigue
However, in the convex lens 201 in the multi-view 3D display system, the sampling interval for the viewpoint images to be generated is too wide

Embodiment Construction

[0048] The conventional HMDs described above suffer from the following problems.

[0049] In an HMD, the positions of the two eyes relative to the built-in display do not change. Therefore, it is not considered necessary to express motion parallax except that there is a variation in the inter-ocular distance between individuals. If a super multi-view 3D display system is used to display 3D images despite the lack of this need in HMDs, natural visual recognition of 3D images can be expected, as described above.

[0050] However, there is no technology for displaying a correct 3D image based on the layout of the convex lens and the eyepiece lens when a convex lens is provided between the display and the eyepiece lens in an image display device such as an HMD, which has an optical A system in which a virtual image is visually recognized through an eyepiece lens.

[0051] Note that the problem is not limited to the case where a convex lens is provided between the display of the ...

Abstract

An image display device and an image display method are disclosed. The display displays a composite image including elemental pixels. Each element pixel is formed by arranging pixels respectively extracted from images having different viewpoints in one direction. The first optical element includes lenses arranged in the direction to correspond to elemental pixels, and for a specific image, the first optical element emits light rays emitted from pixels respectively included in the elemental pixels in parallel. The second optical element gathers light. The output circuit selects pixels of a specific image included in the specific element pixels, and outputs the pixel values ​​thereof to the display. At this time, as the distance between the first optical element and the second optical element becomes smaller than the focal length of the second optical element, an optical element that is farther from the optical axis of the second optical element along the direction in a specific image is selected. pixels.

Description

technical field [0001] The embodiments discussed herein relate to an image display device and an image display method. Background technique [0002] In wearable computing, a head mounted display (HMD) is known as a display device mounted on the human body. When mounting the HMD on a person's head, the person can have his / her hands free. Therefore, the HMD is expected as an operator assistance display device. [0003] The main components of an HMD are a display that displays moving images or still images and an eyepiece that extends the clear vision range of the display. The HMD has a combination of a pair of displays and eyepieces for each left and right eye, and enables the left and right eyes to view independent images. When the HMD displays a single same image for both left and right eyes, the HMD functions as a two-dimensional display, and when the HMD displays separate images with parallax therebetween as an image for the left eye and an image for the right eye, The...
