Method and Apparatus for Providing a Video Image Having Multiple Focal Lengths |
摘要 |
A method and apparatus for providing a video image having multiple focal lengths includes a multi-focal lens system and a drive mechanism capable of moving the multi-focal lens system through a cyclic path. A plurality of optical images are formed as the multi-focal lens system moves through the cyclic path. An image pickup device is capable of converting each of the plurality of optical images into a corresponding image signal. An image processor is operative to preferably form a composite image signal wherein individual elements of the optical images are selected to provide preferred focus characteristics.
