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 new three-dimensional imaging system has been needed to overcome the problems of the prior arts using conventional variable focal length lenses, which have slow response time, small focal length variation, and low focusing efficiency, and require a complex mechanism to control it. The three-dimensional imaging system of the present invention uses the variable focal length micromirror array lens. Since the micromirror array lens has many advantages such as very fast response time, large focal length variation, high optical focusing efficiency, large size aperture, low cost, simple mechanism, and so on, the three-dimensional imaging system can get a real-time three-dimensional image with large depth range and high depth resolution.

摘要： The present invention provides a compact automatic focusing system using a Micro-Electro-Mechanical System (MEMS) unit. The automatic focusing system using the MEMS unit has a small volume and low power consumption, and its operation is very reliable, precise, and fast. The MEMS unit for automatic focusing comprises at least one micromirror, at least one micro-actuator, and at least one micro-converter fabricated on the same substrate by microfabrication technology. By fabricating the micromirror, the micro-actuator, the micro-converter on the same substrate, the volume of the automatic focusing system of the present invention can be greatly reduced. The micro-converter converts the in-plane translation of the micro-actuator to out-of-plane translation of the micromirror to provide a large out-of-plane translation range.
