The present invention relates to a retrieval method for searching a first character element string obtained by subjecting a character string to character recognition for a second character element string. The first character element string includes a first character element and the second character element string includes a second character element. A distance relevant to a similarity between the first character element and the second character element is predetermined between the first character element and the second character element. The retrieval method comprises the steps of comparing the distance with a predetermined reference distance, and determining whether the second character element matches the first character element based on a result of the comparison of the distance with the predetermined reference distance.

In an infrared imaging device, shutting meansis configured so that it can be opened/closed and so as to shut off an infrared radiation coming into an optical systemwhen it is closed. During an imaging operation, the shutting meansis opened, and the optical systemcauses an infrared radiation from an objectto form an image on an infrared detector. The infrared detectoroutputs a signal according to the amount of infrared light received by each pixel. Correction meanscorrects sensitivity variations among pixels, the influence of the infrared radiation from the optical system, etc. During a calibration operation, the shutting meansis closed, and the correction meansdetermines a correction coefficient for correcting fluctuations in the amount of infrared radiation from the optical systemby using the output of the infrared detectorimaging the shutting means

An image coding apparatus includes an image feature extraction means for generating character data which includes character codes corresponding to character images included in a document image and auxiliary information indicating the sizes and positions of the respective character images in the document image based on image data indicating the document image. The image coding apparatus generates a predictive document image for the document image based on the character data, and subjects the document image data to arithmetic coding in which the probability model is changed with reference to predictive document image data. In the image coding apparatus, the probabilities of white pixels and black pixels indicated by the probability model are very close to those in the character image, whereby the coding efficiency for the character image data in the arithmetic encoder is improved.

A control method is to monitor a person's attributes and based on the results, in predetermined content of the control, to control equipment to be controlled, further, to monitor said person's peripheral environment and also by using these results to execute said control.

Control method

To provide an image detection method for judging whether a specific image is present in an input image by temporarily holding the input image signal, obtaining data from the held data like a circle having a radius r, calculating the characteristic value of the circular data, judging whether the characteristic value is included in a specific pattern in accordance with the similarity between the characteristic value and a reference characteristic value, obtaining data like a circle having a radius r' different from the radius r when judging that the characteristic value is included in the specific pattern, calculating a new characteristic value, and repeating the operation of judging whether the new characteristic value is included in a specific pattern over circular data having a plurality of radiuses. Thereby, it is possible to efficiently detect the presence or absence of a specific image whose arrangement conditions such as the angle and position in an input image are unknown.

This dielectric resonator microwave oscillator has enhanced negative resistance and positively starts the oscillation even when there is a low reflection coefficient of the resonance circuit. Using a circuit which consists of a capacitor and inductor between the source and the output terminal, a further increasing of negative resistance at the gate of the FET is obtained.
