摘要： Automatic focusing system is provided which comprises a mirror or a plurality of mirrors with a translation device. Automatic focusing can be made by the translation of mirror because focal plane can be changed by the translation of mirror. The translation device makes its motion by the electrostatic, electromagnetic and/or electrothermal forces. The mirror is controlled by the electrical signal from the image processor to get an in-focus image. Also the mirror can be controlled discretely. The image shift by translation is compensated by tilt of mirror and/or image processing.

摘要： An automatic focusing system comprises at least one micromirror array lens, an image sensor, and a signal processor. The micromirror array lens images an object and focuses the image on the image sensor. The image sensor receives the light and converts the photo energy of the light to electrical energy in the form of an electrical signal. The image sensor sends the electrical signal, which carries image data concerning the object, to the signal processor. The signal processor receives the electrical signal, compares the image quality of the image data to its focus criteria, and generates a control signal, which it sends to the micromirror array lens to adjust the focal length of the micromirror array lens. This iterative process is continued until the quality of the image data meets the focus criteria, and the process is completed within the afterimage speed of the human eye.
