Wavelet Transform for Autofocusing Detection Systems

Joewono Widjaja^*

ABSTRACT: Use of wavelet transform for a new autofocusing mechanism is proposed. In comparison with autofocus mechanisms of commercially available camera systems, our proposed method is more accurate. In conjunction with a use of charge-coupled device image sensor, implementation of the method leads to simple and low cost camera systems.
