Abstract
An image input device is provided in which an optical deflector is positioned to divide the image of an object into a plurality of sub-images and to deflect the sub-images to an image sensor via an imaging lens. The images sensed by the image sensor are stored in a memory and combined by an image processor to form a composite image of the object. A hybrid zoom arrangement allows the magnification of an image on a display to be adjusted both mechanically and electronically. Techniques and circuitry for image processing allow a user to remove undesirable motion blur from the real time image and allow an input image to be patch-wise warped into an output image. An optical encoder for accurately determining the position of a deflector such as a mirror has also been provided.
