Most recent cameras are with the function of auto focus,
which can bring the camera into focus on a certain subject automatically.
By taking this term,now some technology of directing a camera gaze toward the specific target is called "auto pan-tilt."

If we can realize this technique with high-rate control and hardly any delay, an object even in large motion will be observed as if it would be static.
Not simply its qualitative interests or vigor but also images with almost no motion blur are expected.
However, a rotating stage, conventional device for auto pan-tilt, cannot give the required high-speed performance on account of its large moment of inertia.

Hence, we developed an novel and alternative device for auto pan-tilt named "Saccade Mirror" with optical mechanism.
Our techniques, 1 ms Auto Pan-Tilt is based on this device, a PC and high-speed camera for image processing. 1 ms derives from its control(1 kHz) and frame rate (1000 fps).
