Abstract
An electronic still camera is disclosed which adjusts focus to an object image by mechanically moving an electronic sensor within the electronic still camera. The electronic sensor is moved along an optical path of the electronic still camera. In this way, the sensor follows the focal plane of the image, thus tracking a focused image.
