Abstract:
1. A method of processing an image acquired using a plenoptic camera having a lenslet array element comprising a plurality of lenslets arranged in an array, the lenslet array element being positioned to refract light from a field lens to a relay lens, the relay lens being positioned and configured to gather light refracted from the lenslet array and to focus the gathered light on to a sensor element; the method comprising: receiving light via a field lens, a lenslet array element, and a relay lens, the relay lens comprising a first set of optical elements and a second set of optical elements, wherein the first set of optical elements is configured to focus light on the second set of optical elements; acquiring an image of a light field using the sensor element, the acquired image including an array or matrix of individual lenslet images; calibrating the image, wherein the calibrating comprises: determining depth information for the light field using the calibrated image; and adjusting the calibrated image using the depth information for the light field to produce an adjusted image.
