我们的目标是研发简单、变焦、可抓拍图像的相机，我们已经做到了这点。
Our goal was to develop something simple that can zoom and capture good images, and we've achieved that.
此款“眼球式相机”有3.5倍光学变焦功能，图像清晰，价格低廉，只有镍币大小（使用此技术，焦距可更高）。
The "eyeball camera" has a 3.5x optical zoom, takes sharp images, is inexpensive to make and is only the size of a nickel. (A higher zoom is possible with the technology.)
