摘要： Methods, systems and apparatuses may provide for technology that identifies a seam area between a pair of images corresponding to a first eye and determines a disparity between the seam area and a reference area at a center line of a reference image corresponding to a second eye. The technology may also automatically adjust one or more pre-stitch parameters of camera sensors associated with the pair of images and the reference image based on the disparity.

摘要： Methods and devices for improving visual perception in challenging vision environments and for some with low vision conditions (including age related macular degeneration, AMD) are disclosed. A plurality of frequently co-pathological conditions that together make undistorted, clear and bright vision challenging are dealt with by managing the nature, amounts and patterns of light reaching the eyes while managing the sensitivity and dynamic ranges of the eyes. For example, the sensitivity of chromophore response to particular wavelengths and the instant status of the visual transduction system are, in some embodiments, measured, monitored and managed.

摘要： A method for decoding a compressed image stream, the image stream having a plurality of frames, each frame consisting of a merged image including pixels from a left image and pixels from a right image. The method involves the steps of receiving each merged image; changing a clock domain from the original input signal to an internal domain; for each merged image, placing at least two adjacent pixels into an input buffer and interpolating an intermediate pixel, for forming a reconstructed left frame and a reconstructed right frame according to provenance of the adjacent pixels; and reconstructing a stereoscopic image stream from the left and right image frames. The invention also teaches a system for decoding a compressed image stream.

摘要： A method, system, and apparatus provide the ability to control a system state of/in an image viewing application using a camera/portable viewing device. A screen of the camera is used to display a virtual reality view and an opening is positioned over a lens of the camera. The screen and physical buttons of the camera are not accessible when the camera is placed into the virtual reality viewing mechanism. An image is acquired from a camera through the opening. Color is used to make choices for operations. Alternatively, based on the toggling of the system state through a light blocking operation, a motion operation is conducted. The motion operation is based on length of time light is blocked and the length controls a speed of the motion operation.

摘要： An augmented reality display system is configured to direct a plurality of parallactically-disparate intra-pupil images into a viewer's eye. The parallactically-disparate intra-pupil images provide different parallax views of a virtual object, and impinge on the pupil from different angles. In the aggregate, the wavefronts of light forming the images approximate a continuous divergent wavefront and provide selectable accommodation cues for the user, depending on the amount of parallax disparity between the intra-pupil images. The amount of parallax disparity is selected using a light source that outputs light for different images from different locations, with spatial differences in the locations of the light output providing differences in the paths that the light takes to the eye, which in turn provide different amounts of parallax disparity. Advantageously, the wavefront divergence, and the accommodation cue provided to the eye of the user, may be varied by appropriate selection of parallax disparity, which may be set by selecting the amount of spatial separation between the locations of light output.

摘要： Optical devices and cognitive prosthetics based on novel components for enhanced human vision, selective video/television display, digital processing and/or unique image analysis to modify the image that a user sees and significantly improve the perception of that user are disclosed. What the user sees is responsive to specific perceptual and informational needs of the user in real time. Devices from the parent patents are herein made both more useful in practical day-to-day use and are more widely applicable to improving the ability of a user to perceive visual stimuli.
