Head mounted display apparatus
The occlusion is faithfully expressed even in the binocular vision in the AR display by a head mounted display apparatus or the like. A head mounted display apparatus 10 includes a lens 12, a lens 13, a camera 14, a camera 15, and a control processor 16. A CG image for a right eye is displayed on the lens 12. A CG image for a left eye is displayed on the lens 13. The camera 14 captures an image for the right eye. The camera 15 captures an image for the left eye. The control processor 16 generates the CG image for the right eye in which occlusion at the time of seeing by the right eye is expressed and the CG image for the left eye in which occlusion at the time of seeing by the left eye is expressed, based on the images captured by the cameras 14 and 15 and projects the generated CG image for the right eye and CG image for the left eye onto the lenses 12 and 13. A center of a lens of the camera 14 is provided at the same position as a center of the lens 12. A center of a lens of the camera 15 is provided at the same position as a center of the lens 13.
HEAD-UP DISPLAY, HEAD-UP DISPLAY SYSTEM, AND MOVABLE BODY
A first input unit in a head-up display obtains a distance to an object. A second input unit obtains a user's eye position. An optical system projects, into the user's field of view, a virtual image of an image displayed on a display panel. A processor causes the display panel to display a parallax image. An optical element causes a first image displayed on the display panel to reach the user's first eye and a second image on the display panel to reach the user's second eye. The processor causes the display panel to display an image element in the parallax image as at least partially superimposed on the object. The processor performs first control to fix, in response to the distance to the object greater than or equal to a predetermined first distance, parallax of the image element to a value other than 0 corresponding to the first distance.
Dynamic uniformity correction
In one embodiment, a computing system may determine, a predicted eye position of a viewer corresponding to a future time moment for displaying a frame. The system may generate a first correction map for the frame based on the predicted eye position of the viewer. The system may retrieve one or more second correction maps used for correcting one or more proceeding frames. The system may generate a third correction map based on the first correction map generated based on the predicted eye position of the viewer and the one or more second correction maps used for correcting the one or more proceeding frames. The system may adjust pixel values of the frame based at least on the third correction map. The system may output the frame with the adjusted pixel values to a display.
HEAD-UP DISPLAY MODULE, HEAD-UP DISPLAY SYSTEM, AND MOVABLE BODY
A head-up display module is mountable on a movable body. The head-up display module includes a first display panel, a first optical element, a drive, a first input unit, and a controller. The first display panel displays a first image. The first optical element reflects image light from the first image emitted from the first display panel. The drive drives the first optical element to change a direction in which the image light from the first image is reflected. The first input unit receives an input of a speed of the movable body. The controller drives the drive in accordance with the speed and controls a display image to be displayed on the first display panel.
OPTICAL SYSTEM FOR A VIRTUAL RETINAL SCAN DISPLAY, DATA GLASSES AND METHOD FOR PROJECTING IMAGE CONTENTS ONTO THE RETINA OF A USER
An optical system for a virtual retinal scan display. The optical system includes: a projector unit including a modulatable light source for generating at least one modulated light beam and including a movable deflection device for the light beam, a scanning projection of an image content being generatable from the at least one light beam as a result of the movement of the movable deflection device; a diverting unit, onto which the image content is projectable and which is configured to map the projected image content into an exit pupil and to guide it onto an eye of a user; an optical exit pupil shifting unit situated in an optical path of the light beam for spatially shifting the exit pupil of an eye box of the optical system in directions which extend at least essentially in parallel to an exit pupil plane of the exit pupil.
INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND INFORMATION PROCESSING PROGRAM
An information processing device according to an embodiment includes a detection unit, a determination unit, and a display control unit. The detection unit detects a wearing state of a wearer with respect to a display device that has optical transparency and projects a plurality of content images duplicated from a single content image toward the eyeballs of the wearer. The determination unit determines whether or not the mounting misalignment is occurring with the wearer on the basis of the detection result of the wearing state detected by the detection unit. In a case where the determination unit determines that the mounting misalignment is occurring, the display control unit displays a notification regarding the mounting misalignment on the display device.
Eyewear including a push-pull lens set
Eyewear having a stereoscopic display including a lens system, and a push-pull lens set including prisms to produce a binocular overlap of two images that coincides with an accommodation plane. The overlap of two virtual images generated by a respective display as seen by the user's two eyes provides user comfort. The stereoscopic display may have a single accommodation plane, where the binocular overlap of the two virtual images depends on the location of the accommodation plane and the depth of the content formed by disparity in the two images. By providing the content at or near the location where the virtual images are at least substantially overlapped, the user viewing comfort is improved. The binocular overlap is controlled by tilting or steering the virtual images inward, such that the overlap occurs at the accommodation plane.
VIEWPOINT DETECTOR AND DISPLAY DEVICE
A viewpoint detector includes an imager that captures an image of an eye of a user and outputs the captured image, and a controller that detects a viewpoint of the user based on the captured image. The controller detects a position of the viewpoint from the captured image, and corrects the detected position of the viewpoint to a corrected viewpoint position with a conversion table.
Determining inter-pupillary distance
A head-mounted display device includes a see-though display providing both eyes of a user with a view of a physical object, a processor, and a non-volatile storage device holding instructions executable by the processor to: display an image that corresponds to the physical object to a first eye of the user at an offset to the physical object; display blocking light to a second eye of the user; in response to alignment user input, move a position of the image relative to the physical object; in response to completion user input, determine the inter-pupillary distance of the user; and calibrate the head-mounted display device based on the inter-pupillary distance.
Camera System
A device for MR/VR systems that includes a two-dimensional array of cameras that capture images of respective portions of a scene. The cameras are positioned along a spherical surface so that the cameras have adjacent fields of view. The entrance pupils of the cameras are positioned at or near the user’s eye while the cameras also form optimized images at the sensor. Methods for reducing the number of cameras in an array, as well as methods for reducing the number of pixels read from the array and processed by the pipeline, are also described.
