Method and apparatus for automatically tracking and photographing a moving object

摘要

A method and an apparatus for automatically tracking and photographing a moving object for use in a camera. The apparatus includes a plurality of memory units for sequentially storing image signals input to the camera according to a predetermined time period. A sensor is used to sense a difference between corresponding address bits in the respective memory locations. A voltage detector is used to select a voltage for angularly shifting a focal point of the camera by a distance proportional to the output of the sensor. A driving motor is used to angularly shift the focal point of the camera.
