Abstract
An image capturing apparatus for capturing a sequence of subsections of a flat field subject image. The image capturing apparatus includes a camera assembly, preferably including a digital camera, and a lighting assembly. The image capturing apparatus further includes an image positioning jig for moving the subject image to a series of predetermined positions relative to the camera assembly for the capture of the subsections of the subject image by the camera. The image positioning jig includes a backing plate for supporting the subject image in an image plane, and a positioning rail for abutting an edge of the subject image for slidable movement along the X-axis of the image plane. A plurality of rail locators are arranged on the backing plate for attaching the positioning rail to the backing plate at predetermined positions along the Y-axis of the image plane. A plurality of image stops are disposed on the backing plate for positioning the image at predetermined locations along the X-axis of the image plane.
