Paper Abstract

A picture paints a thousand words and those pictures form our universal language. This alone makes picture a very convenient tool. However image processing on the computer is still troublesome and requires lots of memory, thus limiting the wide usage ofpictures in communication. Typical image processing tools using the computer are scanner and video camera, and recently digital cameras have come onto the scene rapidly. This is made possible with the advancement in electronics. Combining this with the optical technology, a simple and convenient image processing system is now possible. The birth ofultra-wide conversion (fish eye) lens. To date, there are a few companies manufacturing fish eye lenses, however these are usually bulky and not suitable for use on the small digital cameras that have come into the market recently. The earliest small size high-resolution digital camera in the market was Olympus with their C-820L model. With that camera model as target, we started to develop a prototype for world's first lightweight FOV 185° wide-angle conversion lens. This new technology is developed for the Internet age and to create new culture in the communication field. The generally accepted view is that image processing on the computer is complicated and only specialists can do the job. Laymen like you and me, and older folks, will find the subject too difficult to handle. However our fish eye lens changes all that.
