Abstract: This document relates to head mounted display devices. One example can include a layer of individually controllable pixels that can be energized to emit light and a layer of lenses that are physically aligned over the pixels. The example can also include a layer of shutters interposed between the pixels and the lenses and configured to be independently transitioned between a transmissive state and an opaque state to limit paths of the emitted light that reach the layer of lenses.

Abstract: Video noise reduction for a video augmented reality system is provided. A head mounted display includes a display unit; a camera for generating frames of display data. A frame store is provided for storing previous frames of displayed information that was sent to the display unit; and a motion processor is provided in communication with the camera, display unit, and the frame store. The motion processor is operable to: identify an area of interest in a current frame of display data; match the area of interest to similar areas in previous frames stored in the frame store; rotate and translate the matched areas of interest from the one or more previous frames stored in the frame store to match the area of interest in the current frame; and average the prior matched areas of interest with the current area of interest to generate a displayed area of interest.

Abstract: Techniques for fabricating an image sensor chip having a curved surface include placing a bending substrate on a first surface of an imaging sensor chip. The first surface of the imaging sensor chip includes light sensors to generate electrical signals in response to receiving light. Fabricating also includes bending the bending substrate so as to impart forces on the image sensor chip to produce a curved imaging sensor chip. A second surface of the curved imaging sensor chip may be adhered to a backside substrate. The second surface is opposite the first surface. The bending substrate may be removed from the first surface of the imaging sensor chip.

Abstract: In some examples, techniques and architectures for operating a device that may be wearable, such as a head-mounted device, may be used for virtual reality applications. A processor of the device may operate by dynamically tracking the cornea, and thus the gaze direction, of a user's eyes. By tracking the gaze direction, retinal velocity of a display image projected onto the retina, measured in the retina coordinate frame may be computed. Display times of image frames viewable by the user may be modified based on the retinal velocity.

Abstract: The subject disclosure is directed towards an image sensor that is controllable curved to adapt for differences in lens focal lengths. Variable data such as focal length data, measured curvature data and/or image quality data is received at a curve controller that curves the sensor based upon the variable data. In one aspect, a camera is provided with a lens having a variable focal length and a sensor capable of being dynamically curved. A curve controller receives image quality data and iteratively uses the image quality data to adjust the curvature to attempt to increase the image quality of a subsequent image to be captured.

Abstract: The subject disclosure is directed towards a curved image sensor that is rotated in one or more rotational directions to compensate for camera movement, e.g., camera shake. In one aspect, sensors such as gyroscopes output camera movement data, which a controller uses to rotate the curved (e.g., hemispherical) image sensor about its center of curvature, e.g., via signals to electrical and/or magnetic movement mechanisms. Image processing may be used by the controller to rotate the image sensor.

At a first delayed time interval from the time of compositing the left side of display image, the right side of display image is composited, and at a second delayed time interval from the time of compositing the left side of display image, the right side of display image is displayed.

Abstract: Techniques for fabricating a semiconductor die having a curved surface can include placing a substantially flat semiconductor die in a recess surface of a concave mold such that corners or edges of the semiconductor die are unconstrained or are the only portions of the semiconductor die in physical contact with the concave mold. The semiconductor die can include through-die cut lines that can lead to substantially less tension in the semiconductor die as compared to the case where the semiconductor die does not include through-die cut lines. Accordingly, such through-die cut lines can allow for achieving relatively large curvatures.
