Abstract
Aspects of the disclosed technology relate to an imaging system and method in which an array camera is employed along with an image processor to make use of parallax convergence differences between different cameras or groups of cameras within an array camera to provide improved super resolution performance.
Claims20
An imaging device comprising:
- an array camera having at least M×N cameras, the camera array configured to capture M×N images, where M and N are positive integers having a product of at least two;
- and
- an image processor operatively coupled to the array camera, the image processor configured to:
- parallax converge images from each camera of the array camera based on different predefined offset points within a predefined sampling pattern to create a sub-pixel sampling pattern;
- and
- sample the sub-pixel sampling pattern at an increased resolution to provide a super resolution output image.

A method of generating an image, the method comprising:
- capturing image data using an array camera having at least N×N cameras, where N is at least two, the array camera producing N×N images, wherein the array camera includes N groups of N cameras;
- for each group of N cameras of the array camera, parallax converging the image from the group of N cameras based on a different predefined offset point within a predefined sampling pattern, producing N group outputs;
- parallax converging the N group outputs based on the different predefined offset points;
- and
- creating a super resolution image by sampling each of the N group outputs based on the predefined offset points within the predefined sampling pattern at an increased resolution.

A method of generating a super resolution image, the method comprising:
- capturing image data using an array camera having at least four cameras;
- parallax converging image data from each camera of the array camera based on different predefined offset points within a predefined sampling pattern to create a sub-pixel sampling pattern;
- and
- sampling the sub-pixel sampling pattern at an increased resolution.
