Paper Abstract

An auto focus video camera system using a bagtype lens was developed. The bagtype lens was formed by pasting two plastic films on a ling spacer and by filling with liquid. Its focus could be controlled quite freely by changing the volume of liquid filled. Focus control signal was obtained by differentiating the CCD video signal. A simple object was brought into the focus automatically within about 20 seconds in this system.
