    Abstract: A three-dimensional display device includes a two-dimensional display displaying a depthwise image, and a variable focal length micromirror array lens receiving light from the two-dimensional display and forming a corresponding image in the required location in space. Each depthwise image represents a portion of an object or scene having the same image depth, and the two-dimensional display displays one depthwise image at a time. The focal length of the variable focal length micromirror array lens changes according to the depth of the depthwise image being displayed. The variable focal length micromirror array lens has enough speed and focusing depth range for the realistic three-dimensional display.

  • Publication number: 20060200500
    Abstract: A method of efficiently recovering a database that can be applied to a mobile communication terminal employing a flash memory as a storage medium is provided. In the flash memory, a database (DB) storage area and a DB recovery area are separately allocated. Images of pages in the DB storage area that are objects to be changed are sequentially read and stored in a memory buffer, and the original images of the pages before change are assigned sequential serial numbers and backed up in the DB recovery area. Then, the images of the pages in the memory buffer are changed according to a transaction. This series of jobs is performed with respect to all pages that are the objects of change. Then, each page in the DB storage area that is the object of the change is updated with a corresponding changed page in the memory buffer.

  • Publication number: 20060139731
    Abstract: The present invention provides a fast optical shutter function by use of the fast movement of the micromirrors. In a micromirror array lens (MMAL), all the micromirrors reflect the incident light to form an image on the image plane. If the micromirrors reflect the incident light out of the optical sensor area, then the optical sensor can not have any optical signal just like the incident light blocked. By just changing the beam path by MMAL motion, the micromirror array lens has a function for optical shutter.

  • Publication number: 20050275927
    Abstract: A micromirror array lens consists of many micromirrors with two degrees of freedom rotation and actuating components. As a reflective variable focal length lens, the array of micromirrors makes all lights scattered from one point of an object converge at one point of image plane. As operational methods for the lens, the actuating components control the positions of micromirrors electrostatically and/or electromagnetically. The optical efficiency of the micromirror array lens is increased by locating a mechanical structure upholding micromirrors and the actuating components under micromirrors. The known semiconductor microelectronics technologies can remove the loss in effective reflective area due to electrode pads and wires. Independent control of each micromirror is possible by known semiconductor microelectronics technologies. The micromirror array can form a lens with arbitrary shape and/or size, as desired.
