The present invention relates to a new eye-contact function providing method which provides a natural eye-contact function to attendances by using a stereo image and a depth image to estimate a precise depth value of the occlusion region and improve a quality of a composite eye-contact image when there are two or more remote attendances in one site at the time of a video conference using a video conference system and an apparatus therefor.

A 3D image display device includes: a display panel that includes a plurality of pixels arranged in a matrix form; and a view point division part that divides the plurality of pixels into a plurality of corresponding view points. The view point division part includes a plurality of view point division units each associated with a lenticular lens tilted at an inclination angle and an inclination angle changing unit for changing the inclination angles of the plurality of the view point division units to correspond to a portrait mode or a landscape mode. The view point division part and the display panel are configured so that a same optimal viewing distance is calculated in portrait mode and landscape mode.

An image processing apparatus includes an information obtaining unit configured to obtain parallax adjustment information with regard to a parallax-adjusted three-dimensional display material and an image transform unit configured to perform an inverse transform processing on the parallax-adjusted three-dimensional display material to be restored to a material before the parallax adjustment on the basis of the parallax adjustment information obtained by the information obtaining unit and generate a two-dimensional display material.

An autostereoscopic display comprises a pixelated display panel comprising an array of single color pixels or an array of sub-pixels of different colors and a view forming arrangement comprising an array of lens elements. The pixels form a hexagonal grid, and the lenses also repeat in a hexagonal grid. A vector p is defined which relates to a mapping between the pixel grid and the lens grid. Regions in the two dimensional space for this vector p are identified which give good or poor banding performance, and the better banding performance regions are selected.

A method includes obtaining volumetric image data generated by an imaging system, generating an uncertainty for each voxel of the volumetric image data, and generating an evaluation volume with volumetric image data based on the generated uncertainty. The method further includes receiving an input identifying a region and/or volume of interest in the evaluation volume, receiving an intended diagnostic type, receiving an evaluation probability level of interest, and receiving an effect direction of interest. The method further includes deforming the evaluation volume to create an artificial volume that reflects an effect of the uncertainty on the intended diagnostic type based on the evaluation probability level of interest and the effect direction of interest. The method further includes visually displaying the deformed evaluation volume.

An object of the present invention is to provide an I/O device, an I/O program, and an I/O method which can be used even by a user who has strabismus, etc. Another object of the present invention is to provide an I/O device, an I/O program, and an I/O method for adjusting the strabismus or eyesight, etc. of a user. In addition, a display device can generate a stereoscopic image, a depth level sensor measures a distance to an object, and a control unit performs display on the display device in accordance with the depth level sensor. A display adjustment mechanism adjusts the angle of the display device.

An automatic vending machine having holographic products comprises: a user interface unit; a display unit comprising one or multiple displays; an image display processing unit for processing to display, on the display unit, a thematic image including a plurality of image objects and one or more three-dimensional product image objects included within the thematic image; and a sale processing unit for processing the sale of an actual product corresponding to the three-dimensional product image object selected for purchase by means of the user interface, wherein the image display processing unit rotates the three-dimensional product image object in accordance with a user input from the user interface unit.

The invention features techniques and systems for presenting two or more perspective views to each eye of the viewer, through division multiplexing of the viewer's entrance-pupil. The system is constituted by a selective-aperture array with each aperture being transparent only to light beams with some special characteristics, at least one display screen for optical information presentation, and other optional elements. The optical message on at least one display screen propagates to the selective-aperture array directly, or be directed to the selective-aperture array or the eye of the viewer by other optional elements. Through selective filtering by the apertures with temporal filtering characteristics or exclusive filtering characteristics, multiple perspective views get presented to an eye of the viewer through the selective-aperture array. Light rays different perspective views superimpose into real spatial light spots that the eye can focus on naturally, resulting in overcoming of the accommodation-convergence conflict.

The object of the present invention is a vibrating grid based space generating device, which enables 3D perception for the user, and which comprises a containing frame (1), an image display surface (20), and a vibrating grid (10) placed in front of the image display surface (20), wherein vertically positioned, angularly arranged blocking strips (13), all having a set depth, are attached in immoveable fashion to the frame (11) of the vibrating grid (10), such that their front edges are radially focused on a single vertical edge at a point along a focal arc (26); and the vibrating grid (10) is connected to the containing frame (1) by means of lower and upper connecting elements (12a, 12b) in a manner that accomplishes vibration in the horizontal plane along an arc of vibration (18).
