  • Publication number: 20240046477
    Abstract: This disclosure provides systems, methods, and devices for image capture and image processing that support capture using a variable aperture (VA) camera. In a first aspect, a method of image processing includes determining a plurality of depths for a scene, the plurality of depths corresponding to a plurality of regions of interest; determining an aperture size for a camera based on the plurality of depths; determining a lens position for the camera based on the aperture size and the plurality of depths; and controlling the camera to adjust a variable aperture (VA) of the camera based on the aperture size and to adjust a lens associated with the variable aperture (VA) based on the lens position. Other aspects and features are also claimed and described.

  • Publication number: 20230319401
    Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media to capture images with subjects at different depths of fields. A method of processing image data includes determining, based on a depth map of a previously captured image, a first distance to a first object and a second distance to a second object; identifying a focal point of a camera lens at least in part using the first distance and the second distance; capturing an image using the focal point as a basis for the capture, the image including a first region corresponding to the first object and a second region corresponding to the second object; and generating a second image from the image at least in part by enhancing at least one of the first region or the second region using a point spread function (PSF).

  • Publication number: 20230015621
    Abstract: The present disclosure provides systems, apparatus, methods, and computer-readable media that support improved image signal processing, particularly in low-light or high dynamic range (HDR) scenes. The image processing techniques may include performing two automatic exposure control (AEC) operations, in which a first AEC operation targets obtaining good conditions for autofocus (AF) operation, and a second AEC operation follows the AF operation and targets obtaining good conditions for an image capture. The image processing techniques may also include communication between the AEC operations and AF operations to coordinate the operations by locking and releasing exposure levels and focus positions as part of the image signal processing.
