Abstract

This paper presents a CMOS system on a chip (SoC) solution to capture focused images for mobile camera phones. In this work, auto focus (AF) lens has been formed by voice coil motor (VCM) type and the image signal processor (ISP) includes a built-in AF control block and AF driver to fully implement AF with fast and accurate performance. The proposed ISP with AF driver can meet constraints such as small size and low cost for mobile camera applications.
