Disclosed is a light guiding valve apparatus including an imaging directional backlight, an illuminator array and an observer tracking system arranged to achieve control of an array of illuminators which may provide a directional display to an observer over a wide lateral and longitudinal viewing range, wherein the number of optical windows presented to the observer as viewing windows is controlled dependent on the lateral and longitudinal position or speed of an observer.

Directional display apparatus

Teleconferencing is performed between two telecommunication devices having a display device and a stereoscopic pair of cameras positioned outside opposed sides of the display device at the same level partway along those sides. The separation between the centers of the cameras is in a range having a lower limit of 60 mm and an upper limit of 110 mm to improve the perceived roundness in a displayed stereoscopic image of a head. In captured stereo images that are video images, a head is segmented and the segmented backgrounds are replaced by replacement images that have a lower degree of perceived stereoscopic depth to compensate for non-linear depth perception in the displayed stereo images. Images are shifted vertically to position an eye-line of a detected face at the level of the stereoscopic pair of cameras of the telecommunication device where the images are displayed, improving the naturalness of the displayed image.

Controlling light sources of a directional backlight

Disclosed is a light guiding valve apparatus including an imaging directional backlight, an illuminator array and an observer tracking system arranged to achieve control of an array of illuminators which may provide a directional display to an observer over a wide lateral and longitudinal viewing range, wherein the luminous intensity of optical windows presented to the observer as viewing windows is controlled dependent on the lateral and longitudinal position or speed of an observer. Further an optical window control system may comprise detection of an observer's hand. An image control system may comprise a method to provide an image that can be switched from a first mode with a first brightness into a second mode with a high brightness region and low brightness region, where the brightness of the second low brightness region is matched to the first brightness.

Control of directional display

Methods and systems for equalizing a holographic image page and for compensating nonlinearity of a holographic data storage channel are disclosed. In one embodiment, a method for equalizing a holographic image page includes receiving the holographic image page and dividing the holographic image page into a plurality of local image regions. The method further includes generating a local alignment error vector for each local image region, computing a local finite impulse response kernel for each local image region according to the corresponding local alignment error vector, and adjusting misaligned pixels of each local image region using the corresponding local finite impulse response kernel.

Method and system for equalizing holographic data pages

The present invention provides systems and methods for logically organizing data for storage and recovery on a data storage medium using a multi-level format. The present invention also provides systems and methods for protecting data stored on data storage medium so that the data may be recovered without errors.

Data protection system

Methods and systems for calculating a wavelength to use for a reference beam in recovering data from a holographic storage medium along with calculating a rotation and a tilt for the storage medium in data recovery. These systems and method include determining intensity levels for a plurality of windows (or subsets of pixels) for a data page as the angle of the reference beam is adjusted. The angles corresponding to the angles where the maximum intensity of light is detected for each window is then used in determining the wavelength, tilt, and rotation in recovering subsequent data pages from the holographic storage medium.
