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.

摘要： This invention provides the two types of Discretely Controlled Micromirror (DCM), which can overcome disadvantages of the conventional electrostatic micromirrors. The first type micromirror is a Variable Supports Discretely Controlled Micromirror (VSDCM), which has a larger displacement range than the conventional electrostatic micromirror. The displacement accuracy of the VSDCM is better than that of the conventional electrostatic micromirror and the low driving voltage is compatible with IC components. The second type of DCM, the Segmented Electrode Discretely Controlled Micromirror (SEDCM) has same disadvantages with the conventional electrostatic micromirror. But the SEDCM is compatible with known microelectronics technologies.

摘要： Television broadcasting systems of this invention comprise an imaging system, and transmission system, and a displaying system. The imaging system captures two-dimensional images of an object at different focal plane, and generates an all-in-focused image and depth profile. A data signal carrying the image data is generated and transmitted over a broadcasting system compatible with commercial two-dimensional television broadcasting, cable, and/or alternative systems. The depth profile is transmitted by using vacant space in video/audio signal within the allocated channel bandwidth. The data signal is received by the displaying system and the extracts the all-in-focused image and depth information from the data signal. The object is restored from all-in-focused image and depth profile and displayed on the displaying system as a three-dimensional spatial image. Viewers having conventional two-dimensional display device can watch enhanced two-dimensional images.

摘要： A discretely controlled micromirror array lens (DCMAL) consists of many discretely controlled micromirrors (DCMs) and actuating components. The actuating components control the positions of DCMs electrostatically. The optical efficiency of the DCMAL is increased by locating a mechanical structure upholding DCMs and the actuating components under DCMs to increase an effective reflective area. The known microelectronics technologies can remove the loss in effective reflective area due to electrode pads and wires. The lens can correct aberrations by controlling DCMs independently. Independent control of each DCM is possible by known microelectronics technologies. The DCM array can also form a lens with arbitrary shape and/or size, or a lens array comprising the lenses with arbitrary shape and/or size.

摘要： A two-dimensional image projection device using array of micromirror array lenses and a random scanning technique is invented. Using the random scanning technique, the light efficiency is nearly doubled than that of the prior art. The invention makes a brighter and less power consuming display device possible. Because each micromirror array lens of array of micromirror array lenses can scan whole image plane, a fast self diagnosis and correction technique can be introduced in displaying device. The Self diagnosis and correction technique makes display device to maintain image quality even a few tens percent of micromirrors do not work properly. Owing to the scanning characteristics of micromirror array lens, the image projection device can express the same number of pixels image with less number of micromirrors than the prior art. This also enables small sized two-dimensional image projector, which can be incorporated in portable electronic equipments.
