  • Patent number: 11936989
    Abstract: An illustrative apparatus may perform gaze-based auto-exposure management of image frames. For example, the apparatus may determine, for an image frame within an image frame sequence captured by an image capture system, auto-exposure values for pixel units into which the image frame is divided. The apparatus may then assign weight values to the pixel units based on a gaze direction of a viewer viewing the image frame sequence. Based on the auto-exposure values determined for the pixel units and the weight values assigned to the pixel units, the apparatus may update one or more auto-exposure parameters for use by the image capture system to capture an additional image frame within the image frame sequence. Corresponding apparatuses, systems, and methods for gaze-based auto-exposure management of image frames are also disclosed.

  • Patent number: 11930286
    Abstract: A method that determines optical path maintenance need before any critical failure in operation of the system is provided. In order to indicate the maintenance need due to the defocusing, the pixel-wise offset value differences between 2 point NUC and 1 point NUC are examined. When the width of this pixel-wise offset difference histogram is greater than predefined threshold, maintenance need is raised. The change in detector characteristics and the need for 2 point NUC/BPR update are proposed to be determined after 1 point NUC by controlling the total number of the bad pixels and bad pixel clusters.

  • Patent number: 11921285
    Abstract: Method and system for on-chip processing to obtain an EDOF image combines interferometry and imaging so the two operations do not interfere with one another but, rather, work together to create an in-focus, true color image of a three-dimensional object. This image has no significant artifacts and requires only limited processing. In addition, a coarse depth map is created in the process which may also be helpful in subsequent usage of the acquired image. A CMOS pixel-array sensor includes circuitry to implement processing at the pixel level.
