A method enabling easy generation of a template handling pattern deformation due to optical conditions or process conditions and suitably detecting pattern position is disclosed. A first method extracts a feature component, that is, symmetry, not affected by optical conditions etc. from the pattern image information and uses it as a template. At the time of pattern detection, image information is projected into a symmetry feature space and matching performed in the feature space to detect a pattern. Suitable template matching can be performed with being affected by pattern deformation. A second method generates a model of a pattern from input pattern data, calculates a plurality of pattern images (virtual models) obtained by imaging of the model for each imaging condition using an image deformation simulator, and determines a template considering their average or correlation.

A radio-frequency device includes a PAA processing portion configured to control a directivity of reception of a receiver antenna device, a received-signal-strength detecting portion configured to detect a strength of the received signal received by the receiver antenna device, and a direction detecting portion configured to detect the direction toward the communication object, on the basis of a direction in which a higher one of two strength values of the received signal respectively detected in first and second maximum-reception-directivity directions of a predetermined angular difference established by the PAA processing portion is minimal. The direction detecting portion is operated based on a fact that the received signal strength is minimal at the bottom of a gain existing in an area of overlapping of two main lobes extending in the respective two directivity directions of the predetermined angular difference, so that the resolution of detection can be made higher than in the case based on the main lobe direction in which the sensitivity of communication with the radio-frequency tag is maximum. Accordingly, the direction toward the radio-frequency tag can be suitably detected.

An LDPC unit decoder included in a signal decoding device is provided with a parity checking unit that is a multiplier for performing multiplication of a check matrix (parity check matrix) and temporary estimated values of an encoded signal, computed by a temporary estimated value computation unit. A check matrix (parity check matrix) holding unit holds the check matrix (parity check matrix). If s and t are natural numbers, s≧t≧2, among s columns extracted from this check matrix (parity check matrix), t columns or less have a linearly independent relationship. These s columns are multiplied at locations where error occurrence frequency is relatively high, with regard to the temporary estimated values. According to this mode, the matrix is composed to include t columns that are linearly independent, that is, t columns that are not linearly dependent. In this way, in a decoded signal series, when errors occur at t locations, since it is possible to avoid multiplying all the linear dependent columns at locations where errors occur, errors with a relatively high frequency of occurrence can be preferably detected.

A computer-readable recording medium recording a worm detection parameter setting program for setting an appropriate worm detection parameter for target environments. When a log reader loads a communication log created within a prescribed time period, a log classifier classifies the entries of the communication log into categories based on communication contents. A frequency distribution creator analyzes the entries of a category, counts the number of appearance of each worm detection parameter value for each object of a preset network unit, and creates frequency distribution information. A threshold derivation unit analyzes the frequency distribution information and derives a threshold value that is used for determining whether a worm is propagating. An output unit outputs to an output device the threshold value for the worm detection parameter for the category, together with the frequency distribution information created by the frequency distribution creator, thereby providing a user with the information.
