1. A method comprising:

  • capturing a primary image with a microlens array at a primary position, the microlens array having at least one microlens deviation that exceeds a first tolerance from a target optical property;

    determining at least one out-of-focus region of the primary image;

    capturing another image with at least one microlens of the microlens array at another position;

    determining a focus of at least one region of the other image relative to a focus of the at least one out-of-focus region of the primary image; and

    constructing a composite image in response to the at least one region of the other image having a sharper focus relative to the focus of the at least one out-of-focus region of the primary image.
