DIGITAL IMAGING METHOD FOR SYNTHETIZING AN IMAGE USING THE DATA RECORDED BY A PLENOPTICAL CAMERA

摘要

Digital imaging system for synthesizing an image using data recorded with a plenoptic camera comprising a photosensor line having a plurality of photosensors; an optics arrangement, including a main lens (10) and a microlens set-up (12) arranged in at least a line of focus of the main lens (10), to direct light from an object (30) to the photosensor line via the main lens (10) and the microlens line set-up (12); a control arrangement to set a relative distance between the photosensor line and the microlens set-up; wherein, for a set of light rays passing through a particular portion of the focal line of the main lens (10), a plurality of the photosensors are arranged to sense different ones of the set of light rays that concurrently arrive at the particular portion of the focal line at different angles of incidence, and to output light data characterizing the sensed light rays; and a processor in a computer set-up programmable to provide image data characterizing a synthesized image as a function of the light sensed at different photosensors, the position of the photosensors relative to the microlens set-up (12), and an angle of incidence of the sensed light upon the focal line of the main lens (10), wherein the focal lengths of each of the microlenses over the at least one-dimensional set-up differ from each other.
