Abstract:
A method for capturing images of an individual to determine wellness for such individual, including establishing baseline physiological data for the individual, and baseline capture condition data for the individual; detecting and identifying the presence of the individual in the image capture environment; providing semantic data associated with the individual; capturing one or more images of the individual during a capture event and determining the capture conditions present during the capture event; using the event capture conditions, the baseline physiological data for the individual and the baseline capture condition data to determine the acceptability of event captured images; and using the acceptable images and the semantic data in determining the wellness of the individual.
Abstract:
An electronic camera for producing an output image of a scene from a captured image signal includes: (a) a first imaging stage comprising a first image sensor for generating a first sensor output; a first lens for forming a first image of the scene on the first image sensor; and a first lens focus adjuster for adjusting focus of the first lens responsive to a first focus detection signal; and (b) a second imaging stage comprising a second image sensor for generating a second sensor output; a second lens for forming a second image of the scene on the second image sensor; and a second lens focus adjuster for adjusting focus of the second lens responsive to a second focus detection signal. A processing stage either (a) selects the sensor output from the first imaging stage as the captured image signal and uses the sensor output from the second imaging stage to generate the first focus detection signal for the selected imaging stage, or (b) selects the sensor output from the second imaging stage as the captured image signal and uses the sensor output from the first imaging stage to generate the second focus detection signal for the selected imaging stage.
Abstract:
A method of producing a digital image with improved resolution during digital zooming, including simultaneously capturing a first low resolution digital image of a scene and a second higher resolution digital image of a portion of substantially the same scene. A composite image is then formed by combining the first low-resolution digital image and a corresponding portion of the high resolution digital image. Digital zooming of the composite image produces a zoomed image with high resolution throughout the zoom range and improved image quality.
Abstract:
In accordance with the teachings of the present invention, a mold comprises a nubbin positioned within the mold, and an actuator positioned within the mold to align the nubbin. The actuator may be implemented with a piezoelectric material, a magnetorestrictive material, an electrorestrictive material, etc. In one embodiment, the actuator is formed into a cylinder and placed around a nubbin in a mold. When the actuator receives a stimulus, the actuator constricts decreasing the size of the inner diameter. Decreasing the size of the inner diameter causes the actuator to constrict and align the nubbin along a centerline.
Abstract:
A multiple group variable focal length lens is provided. The lens has a first lens group including a variable power lens element and is positioned in a stationary manner along an optical axis. The lens also has a second lens group moveably positioned along the optical axis. The variable power lens element can be an electrically controllable liquid lens having a surface with a variable radius of curvature created by two liquids having distinct indices of refraction with one of the liquids having an index of refraction greater than 1.60. Alternatively or additionally, at least one of the liquids used in the liquid lens can include nanoscale particles.

A light-conductive pipe is described comprising a body of light-conductive material having an input face having a first cross sectional perimeter at a first end and an output face having a second cross sectional perimeter at a second end, and at least one integral alignment feature projecting from the body providing a third cross-sectional perimeter larger than at least one of the first or second perimeters of the faces, wherein the projecting alignment feature does not have a surface in the same plane as either face. Also described are integral linear arrays of multiple light-conductive pipes, two-dimensional arrays formed from multiple aligned individual light-conductive pipes or stacked integral linear arrays, and expanding optical faceplates formed from such two-dimensional arrays. Tiled flat-panel display systems may be formed from a plurality of modules aligned in an array, each module comprising a flat-panel display having a plurality of pixels and an expanding optical faceplate formed from such two-dimensional arrays.

An interactive head-mounted eyepiece with an integrated processor for handling content for display and an integrated image source for introducing the content to an optical assembly through which the user views a surrounding environment and the displayed content, wherein the height of the image source is at least 80% of a display active area width of the optical assembly.
Abstract:
Operating a switchable head-mounted display apparatus includes: providing a head-mounted display that includes a switchable viewing area that switches between a transparent state and an information display state; operating the head-mounted display in the information viewing state to display image-sequence information; analyzing the image-sequence information to produce a signal estimating the propensity of the image-sequence information to induce motion sickness or symptoms of motion sickness in the user; and modifying the image-sequence information or the state of at least a portion of the switchable viewing area in response to the signal to reduce the propensity of the image-sequence information to induce motion sickness or symptoms of motion sickness in the user.
Abstract:
A method of displaying a video of a scene on a display with reduced motion blur includes: providing the video of a scene having first subframes that have a first input rate and second subframes that have a second input rate, wherein the first subframes correspond to a first region of the display and the second subframes correspond to a second region of the display; and selectively providing the first and second subframes to corresponding regions in the display, and providing the first region of the display with a first update rate and the second region of the display with a second update rate, wherein the first update rate is greater than the second update rate, so that the displayed image has reduced motion blur.
Abstract:
Multiple images are captured where the exposure times for some of the images overlap and the images are spatially overlapped. Charge packets are transferred from one or more portions of pixels after particular integration periods, thereby enabling the portion or portions of pixels to begin another integration period while one or more other portions of pixels continue to integrate charge. Charge packets may be binned during readout of the images from the image sensor. Comparison of two or more images having different lengths of overlapping or non-overlapping exposure periods provides motion information. The multiple images can then be aligned to compensate for motion between the images and assembled into a combined image with an improved signal to noise ratio and reduced motion blur.
