A low-vision viewer magnifies the face-up source material in the visual field of a camera and displays the magnified image on a VDU or other display means. In a static mode, the camera captures and stores a high-resolution image of the source material. This high-resolution image can be manipulated and subsequently displayed on the VDU. In a live mode, the camera captures a low resolution image of the source material or a high resolution image of a section of the source material to provide a high frame rate for full motion video. In the live capture mode, the low-vision user can move their view around the source material and zoom in on a desired section of interest. The same camera is used in either static or live modes.
