ACKNOWLEDGMENT

Completing a seminar right on schedule is no doubt a demanding and daunting task. I was

fortunate to have my assistance of many people in this effort. I would like to mention some names

while many others might go unmentioned.

It is my pleasure to acknowledge the help I have received from individuals and institute. I

would like to thank the college in general and our principal Dr. N. C. Hiremath in particular for the

excellent facilities provided.

I am very thankful and obliged to our HOD Prof. S. B. Akkole for his encouragement and

insightful comments at virtually all stages of my seminar.

I also wish to express my warm and grateful thank to my respected guide

Prof. N. K. Honnagoudar for giving me the advice and valuable guidance.

I am very thankful to Prof. B. M. Shetake (seminar coordinator) for providing valuable

suggestions in carrying out this seminar successfully.

I also thank all professors and staff of ECE department for their constant encouragement.

I would like to thank my parents, classmates and friends who directly or indirectly helped me

in completing this seminar.

Abstract

As Digital Still Cameras (DSC) become smaller, cheaper and higher in resolution, photographs are

increasingly prone to blurring from shaky hands. Optical image stabilization (OIS) is an effective

solution that addresses the quality of images, and is an idea that has been around for at least 30 years.

It has only recently made its way into the low-cost consumer camera market, and will soon be

migrating to the higher end camera phones. This paper provides an overview of common design

practices and considerations for optical image stabilization and how silicon-based MEMS dual-axis

gyroscopes with their size, cost and performance advantages are enabling this vital function for

image capturing devices.
