Abstract
A sensing device includes a light-field image sensor and a sensing circuit. The light-field image sensor includes a plurality of subarrays. One of the subarrays corresponds to sensing pixels. The sensing pixels are to capture images of an object on or in proximity to a display panel by sensing lights from different directions. The sensing circuit is to generate a plurality of sub-images of the object according to sensing signals of the sensing pixels and shift each of the sub-images of the object by an off-set to generate an image data.
