Abstract: Disclosed are several embodiments of panning and zooming devices that may assist individuals with low vision. The present invention employs imaging devices that capture an image and then select a smaller portion of the image for full display. The size of the selected portion of the captured image determines the magnification that is achieved. Further, different portions of the captured image can be selected to provide for panning of the image. In this fashion, a stationary mounted camera can be used which allows an image to be both panned and zoomed. Further, automated techniques can be used for panning and zooming control. Small aperture optics are used so that images can be focused for a large depth of field which allows the present invention to be employed without the necessity for using expensive optical focusing techniques. Electrical zooming and panning also allows the device of the present invention to be employed for both writing on and reading a document.

Abstract: A video camera including a stopped down lens diameter. An opaque material with a small aperture size is placed over the camera lens. The small aperture allows the user to vary the image size of the object to be viewed by moving the camera toward or away from the object. At the same time the blur circle diameter is maintained within acceptable user limits.
