Hybrid multiplexed 3d display and displaying method thereof

Номер: US20120002124A1
Автор: Chao-Hsu Tsai, Kuen Lee, Kuo-Chung Huang
Принадлежит: Industrial Technology Research Institute ITRI

A hybrid multiplexed 3D display and a displaying method thereof. The hybrid multiplexed 3D display includes an image display, a light source and an image splitter. The image display generates a view image. The light source sequentially generates light of multiple colors transmitted through the image display. The image splitter disposed above or below the image display causes image data, which is generated after the light is transmitted through the image display, to emit toward two or more than two view directions. Thus, the image viewed by a user has at least two views to achieve a stereoscopic visual effect.

Разборный линзовый стереоскоп

Номер: RU0000201761U1
Автор: Данил Владимирович Рябой
Принадлежит: Данил Владимирович Рябой

Настоящее устройство относится к стереоскопии, а именно к приборам для просмотра объемного изображения типа параллельная стереопара. Параллельная стереопара - это вид представления стереоизображения, при котором изображения для левого и правого глаза наблюдателя располагаются на носителе одно рядом с другим, соответственно, слева и справа.Задача, на достижение которой направлено заявленное техническое решение, заключается в получении недорогого технологичного стереоскопа для высококачественного просмотра стереопар на карточках и смартфонах разного размера, габариты которого в исходном состоянии позволяют вкладывать его в журналы и буклеты.Конструкция стереоскопа включает гибкую упругую тонкостенную пластину, панель для удержания окулярных линз, окулярные линзы, носитель стереопары.Гибкая упругая пластина, изгибаемая при сборке стереоскопа, удерживает в параллельных плоскостях носитель стереопар и плоскую панель с окулярными линзами. Изменение кривизны изгиба пластины позволяет устанавливать носители стереопар разного размера. Для увеличения диапазона размеров носителей стереопар, гибкую упругую пластину можно выполнить составной. Разделение упругой пластины на части позволяет уменьшить габариты стереоскопа в исходном состоянии.Линзы имеют возможность двигаться вдоль панели, на которую они установлены. Так происходит настройка межлинзового расстояния.Грубая регулировка фокусного расстояния осуществляется посредством вариативной установки панели с линзами в подходящие установочные прорези на упругой пластине, которых предусмотрено несколько. Точная регулировка фокусного расстояния осуществляется прогибом панели с линзами.Сборка стереоскопа осуществляется с помощью выступов, прорезей, пазов и отгибаемых клапанов без крепежных деталей или адгезивных материалов.В разобранном состоянии стереоскоп компактен и удобен в хранении и переноске.

Three-dimensional information is presented directly on the surface of a target three-dimensional object without using a display device such as a display monitor and an HUD. Spatially coded light patterns are projected from two projectors on a target object surface. The light projected from the two projectors are added up on the object surface to produce unified color and luminance. On the object surface, light is simply added up, so that a pattern whose color and brightness correspond to distance and height appears. Hence, a distance to an object or a three-dimensional shape of an object can be highlighted by the color and brightness presented on the object for perception by human beings.

A method and an apparatus for generating an image with shallow depth of field, suitable for a three-dimensional imaging system having a left lens and a right lens, are provided. First, the left lens and the right lens are used to capture a left-eye image and a right-eye image. Next, a disparity between each of a plurality of corresponding pixels in the left and right-eye images is calculated. Then, the depth information of each pixel is estimated according to a focus of the left and right lens, a lens pitch between the left lens and the right lens, and the calculated disparity of each pixel. Finally, the pixels in the left-eye image and the right-eye image are blurred according to the focus of the left lens and the right lens and the estimated depth information of each pixel, so as to obtain the image with shallow depth of field.

A display apparatus includes: a display unit that displays a two-dimensional image; and a variable lens array disposed to face the display unit, wherein the variable lens array includes a variable phase difference layer that receives incident linearly polarized light polarized in a first direction and allows the linearly polarized light polarized in the same direction to exit or allows linearly polarized light polarized in a second direction switched from the first direction and different therefrom to exit, and an optically anisotropic layer that receives the light having exited out of the variable phase difference layer and works as a lens array for one of the light polarized in the first direction and the light polarized in the second direction whereas working as a transparent layer for the other light.

3D liquid crystal shutter glasses include a pair of LCD lenses ( 1 ), and a control circuit ( 100 ) associated with the LCD lenses. The LCD lens includes an LCD-glass layer ( 2 ), a front polarizing filter ( 3 ), and a transparent scratchproof layer ( 4 ) laminated together. The control circuit includes a sync signal receiver ( 5 ), an LCD driver ( 6 ) for controlling LCD lenses, a boost circuitry ( 7 ) associated with LCD driver for outputting a drive voltage to the LCD driver, a CPU ( 8 ) which is respectively associated with the receiver, LCD driver, and boost circuitry for controlling operation of the same, and a power supply module ( 11 ) for powering the control circuit. The lenses prevent light in environment affecting and flaring thereon. The light transmittance of the lenses is approximated to 40%. Accordingly, the 3D glasses present the user brighter and lively image in higher quality, and avoid hurting user's eyesight.
