Abstract
A light field imaging system captures different images provide views that are shifted by sub-pixel amounts relative to one another. These views can be combined to produce a higher resolution digital image of the object.
Claims20
A light field imaging system for producing an image of an object, the light field imaging system comprising:
- a primary optical subsystem that forms an optical image of an object, the optical image located at an image plane of the primary optical subsystem;
- a light field sensor module comprising a secondary imaging array and a sensor array, the secondary imaging array imaging a pupil of the primary optical subsystem onto the sensor array, the secondary imaging array displaced from the image plane so that the sensor array is configured to capture an array of multiplexed views of the object;
- and
- a processing module configured to determine one or more optical parameters to achieve a desired resolution enhancement value, wherein the primary optical subsystem and/or light field sensor module are adjustable according to the one or more optical parameters.
A method for producing an image of an object using a light field imaging system, the light field imaging system comprising a primary optical subsystem and a light field sensor module having a secondary imaging array and a sensor array, the method comprising:
- determining one or more optical parameters to achieve a desired resolution enhancement value;
- adjusting the light field imaging system according to the one or more optical parameters;
- and
- capturing an array of multiplexed views of the object, with the light field imaging system adjusted according to the one or more optical parameters.
A non-transitory computer-readable storage medium storing executable computer program instructions for producing an image of an object using a light field imaging system, the light field imaging system comprising a primary optical subsystem and a light field sensor module having a secondary imaging array and a sensor array, the instructions executable by a processor and causing the light field imaging system to perform a method comprising:
- determining one or more optical parameters to achieve a desired resolution enhancement value;
- adjusting the light field imaging system according to the one or more optical parameters;
- and
- capturing an array of multiplexed views of the object, with the light field imaging system adjusted according to the one or more optical parameters.
