IMAGING DEVICE HAVING LIGHT FIELD IMAGE SENSOR

摘要

A method of imaging a target object with an imaging reader. The method includes the following: (1) detecting light from the target object through a lens arrangement with an image sensor to generate light-field data; (2) generating a stream of image data including image data representing an expected in-focus image of the target object, and (3) processing the expected in-focus image of the target object to decode a barcode on the target object. The image sensor includes an array of photosensitive elements and an array of microlenses that overlays the array of photosensitive elements located at a focus plane of the microlens.
