  • Publication number: 20200237214
    Abstract: Introduced here are retinal cameras having optical stops whose size and/or position can be modified to increase the size of the space in which an eye can move while being imaged. In some embodiments, an optical stop is mechanically moved to recover retinal image quality as the subject shifts their eye. In some embodiments, an optical stop is digitally created using a pixelated liquid crystal display (LCD) layer having multiple pixels that are individually controllably. In some embodiments, multiple non-pixelated LCD layers are connected to one another to form a variable transmission stack, and each LCD layer within the variable transmission stack may be offset from the other LCD layers. In such embodiments, the optical stop can be moved by changing which LCD layer is active at a given point in time.

  • Patent number: 10702142
    Abstract: A technique for performing a visual field test on an eye includes sequentially presenting visual stimuli to the eye on a display. A gaze direction of the eye is monitored with a camera to identify when the gaze direction has drifted from a fixation target. A first intended position associated with a first visual stimulus of the visual stimuli is offset to compensate for drifting of the gaze direction from the fixation target when the gaze direction is determined to have drifted during presentation of the first visual stimulus. User inputs indicating whether the user acknowledges observance of each of the visual stimuli presented are registered.

    Abstract: An imaging system for low-power and low data-rate applications is provided. The imaging system comprises a pixel array having a plurality of photosensitive elements (pixels) divided into a plurality of groups of photosensitive elements (super pixels). An image processor is operably connected to the pixel array and configured to selectively operate each group of photosensitive elements in either (i) a high resolution mode in which the pixel array outputs readout voltages corresponding to all of the photosensitive elements in the respective group of photosensitive elements or (ii) a low resolution mode in which the pixel array outputs readout voltages corresponding to only a subset of the photosensitive elements in the respective group of photosensitive elements. Groups of photosensitive elements corresponding to detected motion in each image frame are operated in the high resolution mode, while the remaining groups of photosensitive elements are operated in the low resolution mode.
