METHOD OF USING A LIGHT-FIELD CAMERA TO GENERATE A FULL DEPTH-OF-FIELD IMAGE, AND LIGHT FIELD CAMERA IMPLEMENTING THE METHOD

摘要

A method is provided to generate a full depth-of-field image using a light-field camera that includes a main lens, a micro-lens array, a light sensing component, and an image processing unit. The micro-lens array forms a plurality of micro-images at different positions of the light sensing component. The image processing unit obtains, for each of the micro-images, an image pixel value according to one of the pixels that is disposed at a specific position of the micro-image, and arranges the image pixel values obtained for the micro-images according to positions of the micro-images on the light sensing component to generate the full depth-of-field image.

1. A method of using a light-field camera to generate a full depth-of-field image, the light-field camera including a main lens for collecting light field information from a scene, a micro-lens array that includes a plurality of microlenses, a light sensing component, and an image processing unit, said method comprising:
(a) forming, using the micro-lens array, a plurality of micro-images at different positions of the light sensing component according to the light field information collected by the main lens, each of the micro-images including a plurality of pixels; (b) for each of the micro-images, obtaining, by the image processing unit, an image pixel value according to one of the pixels that is disposed at a specific position of the micro-image, wherein the specific positions of the micro-images correspond to each other; and (c) arranging, by the image processing unit, the image pixel values obtained for the micro-images according to positions of the micro-images on the light sensing component to generate the full depth-of-field image.
