A pattern for producing a moiré image with a sense of movement and technique for creating such patterns. A moiré display includes: a first pattern; and a second pattern disposed offset from the first pattern by a predetermined distance, the second pattern having a phase which continuously changes relative to the first pattern in at least one region. For example, a moiré image with a sense of movement can be produced when the second pattern has a phase that changes according to a function in at least one section. Accordingly, a moiré image with a sense of natural movement can be produced by inputting an input image and data such as a feature value of the input image.

Moiré displays, devices for generating moiré-producing pattern, systems for generating moiré-producing pattern, and methods for generating moiré-producing pattern

The problem addressed lies in providing a conductive film, a touch panel and a display device which make it possible to suppress a deterioration in the quality of images observed on the display device. In a power spectrum obtained by means of a two-dimensional Fourier transform of each of an electrode wire pattern formed from electrode wires which bend irregularly and a reference pattern formed by regular bent lines, a value obtained by dividing, at predetermined frequency widths, the cumulative value of spectral intensity of each frequency width by the frequency width is a spectral density, and a first evaluation value, which is a common logarithm of a value obtained by dividing the cumulative value of the spectral density in a defined frequency region of the electrode wire pattern by the cumulative value of the spectral density in a defined frequency region of the reference pattern, is 3.6 or less.

Conductive film, touch panel, and display device

[Problem] The problem addressed by the present invention lies in providing a conductive film, a touch panel and a display device which make it possible to suppress a reduction in the quality of an image observed on a display device. [Solution] A drive latticeDL includes an enlargement region, and a sensing latticeSL includes a facing region lying over the enlargement region with a transparent dielectric layer therebetween. When one of the directions in which a plurality of sensing electrode wiresSR are arranged in the facing region is a placement direction, and, in the placement direction, the interval at which drive electrode wiresDR in the enlargement region are arranged is greater than the interval at which the sensing electrode wiresSR in the facing region are arranged, and the enlargement region and the facing region are seen from a position in front of said regions, then one drive electrode wireDR is positioned between two sensing electrode wiresSR which are adjacent to each other in the placement direction.

A code-division multiple-access system has a downstream channel for transmission from a base station to a number of mobile stations, and an upstream channel for transmission from the mobile stations to the base station. On the downstream channel, each mobile station's spreading code is divided into two parts, which modulate data transmitted on in-phase and quadrature carriers, respectively, thereby enabling the length of the spreading code to be doubled without increasing the chip rate. On the upstream channel, as soon as a symbol is received from one mobile station, it is despread to estimate its value, then respread and canceled as interference with respect to the other mobile stations, these processes being iterated in a cyclic order of the mobile stations.

Features are extracted from a sampled input signal by performing first linear predictive analyses of different first orders p on the sample values and performing second linear predictive analyses of different second orders q on the residuals of the first analyses. An optimum first order p is selected using information entropy values representing the information content of the residuals of the second linear predictive analyses. One or more optimum second orders q are selected on the basis of changes in these information entropy values. The optimum first and second orders are output as features. Further linear predictive analyses can be carried out to obtain higher-order features. Useful features are obtained even for nonstationary input signals.

Multi-stage linear predictive analysis circuit

A circuit for pattern matching on the frequency axis which inlcudes a first transformation section having an adaptive filter which is generally identical to an adaptive finite impulse response filter, but with its delay elements having been replaced by all-pass filters. The first transformation section performs frequency transformation on an input signal and is characterized by utilizing as tap coefficients for the adaptive filter, linear predictive analysis coefficients of the input speech signal. The first transformation section outputs linear predictive analysis coefficients of the frequency transformed input signal. A second transformation section is similar to the first transformation section but the tap coefficients of its adaptive filter are linear predictive analysis coefficients of a reference speech signal. A control section calculates a distance between the respective linear predictive analysis coefficients output from the first and second transformation sections, calculates controlling parameters of the filters of the all-pass filters of the transformation sections so as to minimize this distance, and generates a pattern matching residual output on the frequency axis.
