摘要： Supplementary information related to original data is embedded in the original data without being lost or altered and without degrading the quality of the original data. A photographing condition or the like regarding photographing of the original image data is generated as the supplementary information by supplementary information generating means and stored in a database on a network by supplementary information storing means. Storage management information such as a URL address of where the supplementary information is stored is generated by storage management information generating means and embedded by embedding means in the original image data by using deep layer encryption. The original image data in which the storage management information has been embedded are recorded in a recording medium. Since the storage management information has a smaller amount of data than the supplementary information, quality of the original data is prevented from being degraded even when the storage management information is embedded in the original image data.

摘要： An intruding object detecting method and an intruding object detecting apparatus for judging whether an detected object is an intruding object or not even in the condition that there are shadows of moving objects other than target objects to be detected, such as shaking trees, leaves thereof, etc. An image signal is supplied from an image pickup device; a moving object is extracted from the image signal by a subtraction method; division is made between the image signal and a reference background image signal for every pixel so as to produce a ratio image; a histogram of luminance values (pixel values) is calculated on a part of the ratio image corresponding to the moving object extracted in the extracting step; a pixel value on the part of the ratio image corresponding to the extracted moving object is calculated in ratio representation from the calculated histogram; the calculated pixel value in ratio representation is estimated; and the extracted moving object is judged to be an intruding object or not, on the basis of the estimation of the pixel value in ratio representation. Thus, intruding objects are detected in the field of view to be monitored.

摘要： When sharpness processing is carried out on image data coded after being decomposed into multiple resolution spaces and attached with sharpness processing information regarding a highest resolution image, appropriate sharpness processing can also be carried out on image data at an intermediate resolution. A coded image file storing data having been coded after being decomposed into multiple resolution spaces is stored in an image server together with information regarding sharpness processing to be carried out on the highest resolution image. Coded image data at an intermediate resolution are read from the coded image file, and decompressed by decompression means to obtain restored image data. Parameter setting means sets a parameter for sharpness processing to be carried out on the restored image data, based on the information and the resolution of the coded image data. Sharpness processing is carried out by sharpness processing means on the restored image data based on the parameter, and the processed image data are reproduced by reproduction means.

摘要： An original image signal, which represents an original image and are composed of original image signal components representing a plurality of sampling points, that are arrayed at predetermined intervals and in a lattice-like form, is obtained. A judgment is made as to whether an interpolation point belongs to an image edge portion, at which the change in the original image signal is sharp, or belongs to a flat portion, at which the change in the original image signal is unsharp. Interpolating operation processes, one of which is to be employed for the interpolation point, is changed over to each other in accordance with the results of the judgment. Interpolated image signal components corresponding to interpolation points are thereby obtained from the interpolating operation processes such that a visible image, in which a character pattern and an image edge portion are free from any step-like pattern and are sharp and a flat portion has an appropriate level of sharpness, can be reproduced from the interpolated image signal components.

摘要： When an image signal representing a radiation image is compressed and decompressed, and a visible radiation image is reproduced from the decompressed image signal, a compressing process to be employed is changed in accordance with conditions, under which the image signal before being subjected to compression processing has been generated. A moire is thereby prevented from occurring on a reproduced radiation image, the compression processing speed and the compressibility are kept high, and the image quality (the sharpness) of the reproduced radiation image is prevented from becoming worse.

摘要： A MIM nonlinear device is provided having a large nonlinearity coefficient that represents the sharpness of the voltage-current characteristic. A liquid-crystal display panel may be manufactured using the device to exhibit high image-quality. A method for manufacturing such a MIM nonlinear device is also provided. A MIM nonlinear device may include a first conductive film, an insulating film and a second conductive film laminated on a substrate. The insulating film may contain water at a content gradient descending in the direction of the film thickness from the surface facing the second conductive film. The hydrogen spectrum that is derived from the water and obtained by a secondary ion-mass spectrography (SIMS) elemental analysis with the radiation of cesium primary ions exhibits a peak near a surface of the insulating film facing the second conductive film. Additionally, the thermal desorption spectroscopy of the insulating film has a peak derived from water in the insulating film within a range of 220.degree. C..+-.5.degree. C.

摘要： Frequency signals of a plurality of different frequency bands are obtained by transforming each of image signals into a multi-resolution space. Each image signal represents one of radiation images of a single object, which have been formed respectively with a plurality of kinds of radiation having different energy distributions and in which different images of at least part of the object are embedded. Signal components of the frequency signals, which are of an identical frequency band and correspond to different image signals, are weighted with weight factors, which are set in accordance with the frequency band, the signal components representing corresponding picture elements in frequency images represented by the frequency signals. The weighted signal components of the frequency signals are subtracted from one another. Difference signals are thus obtained for the plurality of the different frequency bands. An inverse transform is carried out on the difference signals, and an energy subtraction signal is thereby obtained.

摘要： Radiation images of an object, which have been recorded on recording media and in which different images of at least part of the object are embedded, are read out from the recording media, and a plurality of original image signals, each of which is made up of a series of image signal components, are thereby obtained. The image signal components of the original image signals, which represent corresponding picture elements in the radiation images, are then subtracted from each other, and a difference signal representing an image of a specific structure of the object is thereby obtained. A smoothing process is carried out on an original image signal, and a smoothed image signal is thereby obtained. The image signal components of the original image signal and the difference signal, which represent corresponding picture elements in the images, are weighted such that the weight given to the original image signal may be made larger as the image density represented by the smoothed image signal with respect to a picture element becomes lower. The weighted image signal components are then averaged. A composite image signal obtained from the weighted averaging process is utilized for reproduction of a visible radiation image of the object.
