IMAGE PROCESSING APPARATUS AND IMAGE REFOCUSING METHOD

摘要

An image refocusing method for use in an image processing apparatus is provided. The image processing apparatus has an image capturing unit and an image processing unit. The method has the following steps of: receiving lights of a scene via the image capturing unit to output a raw image having information of different views; rearranging the raw image from the image sensor to obtain multiple different view sub-images; performing a refocusing process to at least one specific view sub-image of the different view sub-images corresponding to a specific view to generate multiple refocused view images, wherein a first focusing position of the refocused view images is different from a second focusing position of the at least one specific view sub-image; and outputting the refocused view images to a stereoscopic display device.

主权项

1. An image processing apparatus, comprising
an image capturing unit, comprising:
a primary lens;a lens array comprising multiple sub-lenses arranged in a direction perpendicular to a light axis of the primary lens; andan image sensor configured to receive lights of a scene passing through the primary lens and the lens array, and output a raw image having information of different views; and an image processing unit configured to rearrange the raw image from the image sensor to obtain multiple different view sub-images, and perform a refocusing process to at least one specific view sub-image of the different view sub-images corresponding to a specific view to generate multiple refocused view images, wherein a first focusing position of the refocused view images is different from a second focusing position of the at least one specific view sub-image, wherein the processing unit further outputs the refocused view images to a stereoscopic display device.
