  • Patent number: 11509816
    Abstract: An image processing apparatus includes a display unit configured to display an image captured via an optical system, an estimation unit configured to estimate a gazing point position of a user on a display unit, and a control unit configured to change a zoom position of an image displayed on the display unit. When start is instructed of image pickup assist control, the control unit zooms out the image displayed on the display unit from a first zoom position to a second zoom position on more wide-angle side than the first zoom position. When stop is instructed of the image pickup assist control, the control unit zooms in on a zoom-out image from the second zoom position to a third zoom position on more telephoto side than the second zoom position, based on the gazing point position estimated by the estimation unit.

    Abstract: Methods, systems, and devices to improve the assessment of visual function and overcoming limitations of current methods to identify the visual function that potentially could be reached by a given eye. Multiple eye tests including visual stimuli plus optical measurement components, and methods to combine the results, identify and quantify sources of decreased vision resulting from optical sources, such as a lens and cornea as distinguished from retinal sources. By identifying potentially correctable optical sources of decreased vision, and overcoming physiological limitations such as size of the eye's pupil, the visual benefits of treatment such as by cataract or corneal surgery are distinguished from retinal pathology that requires medical intervention. The devices and methods provide metrics that include an expected value of the visual function and sources of variability including both optical and neural components, to guide treatment and improve clinical trials.

  • Patent number: 11093034
    Abstract: A method of tracking a gaze position of an eye in a target space in a field of view of the eye over an eye tracking period includes performing a plurality of scans of the eye with infrared light within the eye tracking period. Each scan includes generating infrared light signals over a scan period and projecting the infrared light signals from a plurality of virtual light projectors to the eye to form a plurality of illumination areas on the eye. Reflections of the infrared light signals from the eye are detected for each scan. The gaze position of the eye in the target space is determined from the detected reflections of the infrared light signals for each scan.

  • Patent number: 11051691
    Abstract: A process for ocular analysis is disclosed. Aspects of the process display, on a device having a display and a camera sensor, a regimented pattern as a stimulus. The camera sensor captures video of an environment. The process also involves isolating an iris within the environment as a bounded region of the captured video. Facial landmarks are assigned to the iris within the bounded region. Thereafter, raw movement data of the facial landmark in response to the regimented pattern is extracted from the captured video. The raw movement data is used to create filtered movement data (e.g., data that has been checked for errors). The process also compares the filtered movement data to a predetermined movement response that is based on the regimented pattern. From the comparison, a performance score is generated. The performance score is used to generate an output.

  • Patent number: 11042205
    Abstract: A personal computer system comprises a visual display, an imaging device adapted to provide eye-tracking data by imaging at least one eye of a viewer of the visual display, and identifying means for recognizing the viewer with reference to one of a plurality of predefined personal profiles. The personal computer system further comprises an eye-tracking processor for processing the eye-tracking data. According to the invention, the eye-tracking processor is selectively operable in one of a plurality of personalized active sub-modes associated with said personal profiles. The sub-modes may differ with regard to eye-tracking related or power-management related settings. Further, the identifying means may sense an identified viewer's actual viewing condition (e.g., use of viewing aids or wearing of garments), wherein the imaging device is further operable in a sub-profile mode associated with the determined actual viewing condition.

  • Patent number: 10955915
    Abstract: A preliminary path for light travelling towards a camera via corneal reflection is estimated based on a preliminary position and orientation of an eye. A position where the reflection would appear in images captured by the camera is estimated. A distance is formed between a detected position of a corneal reflection of an illuminator and the estimated position. A second preliminary path for light travelling through the cornea or from the sclera towards a camera is estimated based on the preliminary position and orientation, and a position where the second preliminary path would appear to originate in images captured by this camera is estimated. A distance is formed between a detected edge of a pupil or iris and the estimated position where the second preliminary path would appear to originate. An updated position and/or orientation of the eye is determined using an objective function formed based on the formed distances.
