Abstract
A system constructs a composite image using focus assessment information of image regions.
Claims39
A first method comprising:
- performing a reception of or a transmission of one or more instructions in relation to a second method that includes at least:
- 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 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.

A first system comprising:
- means for performing a reception of or a transmission of one or more instructions in relation to a second system that includes at least:
- means for capturing a primary image with a lens at a primary position, the lens forming a part of a microlens array having at least one microlens deviation that exceeds a first tolerance from a target optical property;
- means for determining at least one out-of-focus region of the primary image;
- means for capturing another image with the lens at another position;
- means for 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
- means for 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.
4 more elements
A system comprising:
- a photo-detector array;
- a microlens array having at least one microlens deviation that exceeds a first tolerance from a target optical property;
- a controller configured to position said microlens array at a primary and another position relative to said photo-detector array and to cause an image capture signal at the primary and the other position;
- and
- an image construction unit configured to construct at least one out-of-focus region of a first image captured at the primary position with a more in-focus region of another image captured at the other position.

A first method comprising:
- performing a reception of or a transmission of one or more instructions in relation to a second method that includes at least:
- capturing a primary image with a microlens array at a primary position, said capturing effected with a photo-detector array having an imaging surface deviation that exceeds a first tolerance from a target surface position;
- determining at least one out-of-focus region of the primary image;
- capturing another image with 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.
