Auto-focusing technique for moving object based on image definition criterion

In previous literature, most researches about auto-focusing technique have based on stationary object. This paper studies the moving target focusing based on image definition. This paper analyzes the image processing frame rate, image delay, focusing step how influence focusing speed and definition and establish the simulation model. Focusing system based on image definition criterion is designed. The system can realize not only the stationary object focusing but also moving object focusing.
