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