Mobile microscope system

Summary

We propose a concept of "mobile microscope" for handheld use, which enable various places to be observable.

We propose an image stabilization method for images from microscope effected by hand-shake. This method is based on high-speed visual feedback with an inclined image sensor to measure the 3D movements of a microscope.

We developed a trial microscope system employing the method without a built-in actuator. Experimental results showed that images from a handheld microscope can be stabilized by the proposal method.

Key Words: microscope, image stabilization, visual feedback
