Abstract
An image capturing unit of a processing apparatus includes a light field camera, an image recorder for recording an image of the workpiece captured by the light field camera, a two-dimensional image processor for generating two-dimensional multi-focal-point images from the image recorded by the image recorder, and a three-dimensional image processor for producing a three-dimensional image by layering the two-dimensional multi-focal-point images. The light field camera includes a main lens, a microlens array having a plurality of microlenses for converging light from the main lens, and an image sensor for capturing the light converged by the microlens array.
