The data defining an object to be holographically reconstructed is first arranged into a number of virtual section layers, each layer defining a two-dimensional object data sets, such that a video hologram data set can be calculated from some or all of these two-dimensional object data sets. The first step is to transform each two-dimensional object data set to a two-dimensional wave field distribution. This wave field distribution is calculated for a virtual observer window in a reference layer at a finite distance from the video hologram layer. Next, the calculated two-dimensional wave field distributions for the virtual observer window, for all two-dimensional object data sets of section layers, are added to define an aggregated observer window data set. Then, the aggregated observer window data set is transformed from the reference layer to the video hologram layer, to generate the video hologram data set for the computer-generated video hologram.

Viewing apparatus for precisely locating and viewing a specific feature or area of the body, particularly in a hard-to-view area. The apparatus includes a viewing device, a general illumination device and a light beam pointer device. The viewing device may be a mirror and/or a camera with monitor. The viewing device is mountable on a freestanding support stand that provides a means for maneuvering the viewing device into a desired position and holding it in that position without the viewing device having to be held in position manually. The light beam pointer device is provided for precisely indicating a specific feature or area reflected in the viewing device, and the general illumination device for illuminating the intended viewing site. The camera and monitor provide a means for viewing a hard-to-view feature or area of the body, particularly on an extremely obese person.

The delivery of targeted advertisements (ads) to wireless mobile handheld display devices (MHDDs) with client specific advertisement and dynamic content for response and feedback is becoming important in advertising. As the return for ads on MHDDs becomes higher, there is a push to show larger and more interactive ads on devices that have small displays. This has created a need to maximize the area available for ad viewing. The need for larger viewing area reduces the area available for call-to-action response enabling switches or inserts on the screen for customer interaction. To overcome this deficiency and provide the necessary end-to-end response capability, hot-spots on the ad image are provided as call-to-action response regions without limitation on the ad viewing area. The use of such hot-spots provides users of MHDDs a preferred interaction mechanism for responding to the advertisement, while maintaining a large ad viewing area.

The invention discloses a monocular multi-view three-dimensional display method. A multi-view optical display structure with limited number of presented views is utilized, a projection lens is introduced between a display view of the multi-view optical display structure and a corresponding view area to amplify the display view, and the interval between adjacent views is reduced, so that two or more pieces of view emergent light information can enter one eye of an observer through two or more adjacent view areas to realize monocular multi-view presentation. The visual discomfort caused by focusing-convergence conflicts of the traditional three-dimensional display technology is avoided, and the visual area distribution area is expanded by arranging two or more multi-view optical display structures/projection lens pairs to cover the two eyes of the observer or provide a larger observation area for the two eyes of the observer.

The invention discloses an optical structure of a fundus camera binocular stereo-imaging system based on an eye model. A universal Gullstrand-LeGrand eye model is introduced to simulate an actual eye, the system comprises two non-coaxial optical paths, the two optical paths perform light splitting through a semi-reflecting and semi-transmitting lens and are composed of ocular lenses close to the eyes and imaging objective lenses close to receiving devices, an imaging device is CCD, the system can obtain two clear fundus images at different viewing angles at the same moment, three-dimensional fundus image reconstruction is performed through algorithm processing, accordingly stereo fundus imaging is achieved, splicing processing can be also performed, and accordingly a fundus observation zone is increased. The fundus camera binocular stereo-imaging system based on the eye model achieves the usage requirements through structural optimization, initial parameter calculation and final image quality analysis and is simple in structure and convenient to operate.

The invention relates to a display apparatus. The display apparatus includes a display unit that time-divisionally displays a plurality of view point images in N divisions, N being an integer equal to or more than 2, a backlight that irradiates the display unit with image display light, and a separation unit that separates M view point images displayed in the same time slot in the display unit, M being an integer equal to or more than 2. The backlight controllably switches the exit direction of light time-divisionally in synch with the timing of time division display by the display unit, the backlight controllably switching the exit direction of light between N directions.
