  • Patent number: 7345818
    Abstract: A projection screen comprises a red-reflecting particle layer, green-reflecting particle layer and blue-reflecting particle layer sequentially stacked on a substrate. In each particle layer, particles are accumulated by eleven cycles in a regularly alignment such as close packed structure. Diameter of red reflecting particles is approximately 280 nm, diameter of green-reflecting particles is approximately 235 nm, and diameter of blue-reflecting particles is approximately 212 nm. Each particles layer is accumulated by self-organized technique. The substrate used here can absorb light of wavelengths other than those of red, green and blue three primary colors.

  • Publication number: 20070097104
    Abstract: The present invention relates to a display apparatus and method for presenting a moving image of less degradation to an observer who is a person viewing a displayed moving image, on the basis of human visual characteristics without unnecessarily increasing the frame rate. A control signal generation section 125 and data line driving circuits 133-1 to 133-4 control display so as to display a moving image made of 105 or more frames/sec on an LCD 131. The LCD 131 displays a moving image made of 105 or more frames/sec on the basis of the control of the control signal generation section 125 and the data line driving circuits 133-1 to 133-4. In the LCD 131, the display of each pixel on the screen is maintained during each frame period. The present invention can be applied to image display systems.

  • Publication number: 20070063961
    Abstract: The present invention relates to a display apparatus and a method, a storage medium, and a program which cause a so-called “hold-type display apparatus” to display an image that makes it difficult for motion blur and jerkiness to be perceived at a lower frame rate. Display of individual pixels of a screen on an LCD 12 is held in each period of a frame. A display controller 11 controls the display of the LCD 12 so as to time-sequentially increase or time-sequentially reduce the brightness of the screen in each period of a frame. The present invention is applicable to a display apparatus.

  • Patent number: 7113931
    Abstract: A fracture structure is grown from a plurality of starting points. A fractal structure, grown from respective starting points and interconnected by interactive growths, forms a neural network. A growth speed originated at a specific starting point is determined by the probability of a material reaching a grown portion from a remote location by means of a diffusion process and the probability of a growth promoting factor reaching a grown portion by means of a diffusion process from a portion grown from a starting point other than the specific one. Anisotropy is introduced into a space in which a fractal structure is to be grown, as required.

  • Patent number: 7061007
    Abstract: Phase transition is controlled by controlling fractal dimension of a fractal-coupled structure overall or locally. For a magnetic material, ferromagnetic phase transition temperature of magnetic particles arranged to have self-similarity is controlled by fractal dimension. For a half-filled electron system confined in a treelike fractal, Mott transition is controlled by fractal dimension of the system. Stronger quantum chaos than conventional ones is generated by adding magnetic impurities to the fractal-coupled structure, and through this process, Anderson transition is controlled.

  • Patent number: 6584234
    Abstract: An image processing apparatus capable of extracting widely viewed features of an entire image and speedily performing image processing, and a method and an information recording medium for such processing. Image data of an original image is obtained by imaging the entire original image with an image pickup unit at a time. An amplitude distribution of a signal is obtained from the image data by fast Fourier transform performed by a fast Fourier transform section of a signal processing unit. An amplitude replacement section replaces the amplitude distribution with a predetermined function using the distance from a center of a frequency plane as a parameter. An inverse fast Fourier transform section forms an image corresponding to the original image by inverse fast Fourier transform from a phase distribution of points obtained by the fast Fourier transform and from an amplitude distribution obtained by the above-described replacement.

  • Patent number: 6525337
    Abstract: An optical and/or electronic device is operated by degeneracy of density of states caused by confinement of electrons in a fractal region having a self-similarity. An AlGaAs/GaAs light emitting device is configured by distributing GaAs quantum dots in a fractal arrangement and confining them in i-type AlGaAs. A single-electron state of the quantum dot array exhibits degeneracy of density of states. Further, a strong quantum chaos is generated to bring about degeneracy of density of states by applying a random magnetic field by addition of a magnetic impurity to the region having a self-similarity.
