Stereoscopic image display device
This document discloses a stereoscopic image display device. In the image display device, a display device displays a first image data and a second image data in a time-dividing manner. A switchable retarder panel is configured to control light emitted from the display device and is made of electrically controlled birefringence (ECB) liquid crystals. Polarization glasses polarize the light emitted from the switchable retarder panel. The polarization glasses comprise a left eyeglass comprising a polarizer having a tilt of 45° about a light absorbing axis, and a right eyeglass comprising a polarizer having a tilt of 135° about the light absorbing axis.
Display driving method, apparatus and display system
Embodiments of the present disclosure provide a display driving method, an apparatus and a display system, and are used for displaying different video signals to different users simultaneously through one display device. The method comprises: receiving a first image signal and a second image signal which correspond to different users respectively; performing a signal process on the first image signal to acquire a processed first image signal, and performing a signal process on the second image signal to acquire a processed second image signal; driving pixels of odd-numbered columns in the pixel array to display the processed first image signal and driving pixels of even-numbered columns in the pixel array to display the processed second image signal, wherein a polarization direction of the emergent light of the pixels of odd-numbered columns is different from that of the emergent light of the pixels of even-numbered columns.
THREE-DIMENTIONAL DISPLAY SYSTEM BASED ON DIVISION MULTIPLEXING OF VIEWER'S ENTRANCE-PUPIL AND DISPLAY METHOD THEREOF
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.
3D DIGITAL PAINTING
A method of digital continuous and simultaneous three-dimensional painting and three-dimensional drawing with steps of providing a digital electronic canvas having at least one display and capable of presenting two pictures for a right eye and a left eye; providing means for creating a continuous 3D virtual canvas by digitally changing a value and sign of horizontal disparity between two images for the right eye and the left eye and their scaling on the digital electronic canvas corresponding to instant virtual distance between the painter and an instant image within the virtual 3D canvas; providing at least one multi-axis input control device allowing digital painting or drawing on the digital electronic canvas; painting within virtual 3D canvas by providing simultaneous appearance of a similar stroke on the images for the right eye and the left eye on the digital electronic canvas.
Stereoscopic image display device including light shielding pattern formed using phase change ink composition
There are provided a stereoscopic image display device and a method of manufacturing the stereoscopic image display device. The stereoscopic image display device includes: an image generation unit generating a left-eye image and a right-eye image; a 3D filter layer disposed above the image generation unit, the 3D filter layer including a first region through which the right-eye image passes and a second region through which the left-eye image passes; and a light shielding pattern disposed between the image generation unit and the 3D filter layer in a position corresponding to a boundary portion between the first region and the second region. The light shielding pattern is formed of a phase change ink composition.
COMPENSATING 3D STEREOSCOPIC IMAGERY
The disclosure features three-dimensional stereoscopic imaging systems and methods that include two image capture devices configured to obtain images of a scene, at least one display screen, and an electronic processor configured to: receive one or more images of the scene from the capture devices, where each of the one or more images includes a lateral dimension and a height; warp the one or more images along their respective lateral dimensions to at least partially correct for disparity distortions associated with displaying the one or more images on the at least one display screen; correct the one or more images by scaling the respective heights of the images along the lateral dimensions of the images so that the height of each image is the same along the images lateral dimension; and display the warped and corrected one or more images on the at least one display screen.
DEVICE AND METHOD FOR THREE-DIMENSIONAL VIDEO COMMUNICATION
A three-dimensional (3D) communication device includes a 3D stereoscopic camera for capturing video and photos in 3D. The device also includes a 3D display, which enables the display of video and photos in 3D that have been captured by a local user's communication device or that have been received from a remote 3D communication device. The 3D communication device may be configured as a handheld standalone device or may alternatively be configured as a modular device, a case, or a dock that can be interfaced with a portable computing device, such as a smart phone, which lacks the capability to capture and view 3D video/photo content. As such, the 3D communication device enables 3D chat or communication between a local user and one or more remote users of the 3D communication device or any other computing device that is configured with suitable communication or chat software.
3D glasses, display apparatus and control method thereof
A display apparatus switching between a two-dimensional (2D) display mode and a three-dimensional (3D) display mode is provided. The display apparatus includes: an imaging device configured to capture an image a pair of 3D glasses worn by a user to view an image displayed in the 3D display mode, wherein the 3D glasses are switchable between a plurality of different states; a transmitter/emitter module configured to remotely control the 3D glasses so as to switch the states of the 3D glasses; and a controller configured to determine whether the user is wearing the 3D glasses based on a state of the 3D glasses in the image captured by the imaging device, and to control the display apparatus to operate in the 3D display mode when it is determined that the user is wearing the 3D glasses.
Imaging apparatus and imaging method
