摘要： A magnetic disc apparatus capable of selectively driving at least two types of the magnetic discs having signal recording portions on their major surfaces and having different recording densities. The magnetic disc apparatus includes a main head carriage mounted for movement on a base block, a supporting arm having its one end supported by a main head carriage, and a magnetic head having a first transducer having a slider, and a first core and adapted for accessing information signals at a first recording density, and a second transducer having a second core and adapted for accessing information signals at a second recording density higher than the first recording density. A magnetic gap for the first transducer and a magnetic gap for the second transducer are formed on the surface of the magnetic head facing the major surface of the magnetic disc. The magnetic disc apparatus also includes a flat-plate-shaped pivoting member for pivotably supporting the magnetic head in a state in which the slider and the base block are disposed on one and the opposite sides of the pivoting member. The magnetic head is changed in its posture to the magnetic disc to follow surface deviation of the magnetic disc produced during driving to achieve correct accessing of the magnetic disc by the magnetic head.

摘要： A plurality of image signals are obtained, which represent a radiation image of a single object or radiation images of the single object, and which have different frequency characteristics, each of the image signals being made up of a series of image signal components. The image signal components of the plurality of the image signals, which image signal components represent corresponding picture elements, are weighted with predetermined weight factors. The weighted image signal components of the plurality of the image signals, which image signal components represent corresponding picture elements, are added to one another, and an addition signal is thereby obtained. The value of the weight factor with respect to the frequency components, which have a low signal-to-noise ratio, is rendered smaller than the value of the weight factor with respect to the frequency components, which have a high signal-to-noise ratio, in accordance with the frequency characteristics of each of the image signals.

摘要： A first image signal representing a radiation image of an object is obtained by exposing a stimulable phosphor sheet, on which the radiation image has been stored, to stimulating rays, which cause the stimulable phosphor sheet to emit light in proportion to the amount of energy stored thereon during its exposure to radiation, the emitted light being detected. A second image signal representing the radiation image is thereafter obtained by again exposing the stimulable phosphor sheet to stimulating rays, the light emitted by the stimulable phosphor sheet being detected. Read-out conditions, under which the second image signal is to be obtained, and/or image processing conditions, under which the second image signal having been obtained is to be image processed, are adjusted on the basis of the first image signal. A storage device stores information representing a standard pattern of radiation images. A signal transforming device transforms the first image signal representing the radiation image into a transformed image signal representing the radiation image, which has been transformed into the standard pattern. A condition adjuster is provided with a neural network, which receives the transformed image signal and feeds out information representing the read-out conditions and/or the image processing conditions.

摘要： An original image is transformed into a multi-resolution space and thereby decomposed into images, each of which is of one of a plurality of different frequency bands. An operation for multiplying by an emphasis coefficient is carried out on an image of a predetermined frequency band, which is among the plurality of the different frequency bands. The emphasis coefficient is set such that the degree of emphasis for an image portion in the image of the predetermined frequency band may become higher than the degree of emphasis for the other portions in the image of the predetermined frequency band, the image portion corresponding to a portion in an image of a frequency band lower than the predetermined frequency band, at which portion the absolute value of the signal value of the image of the lower frequency band is comparatively large. An inverse multi-resolution transform is carried out on the image of the predetermined frequency band, which has been obtained from the operation for multiplying by the emphasis coefficient, and the images of the other frequency bands. A processed image is thereby obtained.

摘要： An original image is transformed into a multi-resolution space and is thereby decomposed into images, each of which is of one of a plurality of different frequency bands. An image of the lowest frequency band, which is lowest among the plurality of the different frequency bands, is processed with the formulag.sub.L '=g.sub.L +f.sub.1 (g.sub.L)=f.sub.2 (g.sub.L)wherein f.sub.1 (g.sub.L) represents a function, the value of which decreases monotonically as the signal value g.sub.L of the image of the lowest frequency band increases. A processed image of the lowest frequency band is obtained from the processing. An inverse multi-resolution transform is then carried out on the processed image of the lowest frequency band and the images of the other frequency bands, and a processed image is thereby obtained.

摘要： In a digital image recording apparatus, an image processing is carried out on a first digital image signal obtained by sampling at a predetermined density an image signal representing an original image. The image processing is for increasing the amount of information carried by the first digital image signal and reducing frequency components of the first digital image signal which are higher than the Nyquist rate of the first digital image signal, thereby obtaining a second digital image signal. The second digital image signal is reproduced on a recording medium at a density higher than the predetermined density, thereby forming an image which is higher in resolution than that obtained from the first digital image signal and equal to that obtained from the first digital image signal in size.

摘要： An interpolating operation is carried out on original image signal components which make up an original image signal representing an original image and represent values of original picture elements arranged in a grid pattern at predetermined intervals to obtain interpolation image signal components representing values of interpolation picture elements arranged in a grid pattern at intervals different from those of the original picture elements. Each interpolation image signal component is operated by multiplying the image signal components for a plurality of original picture elements adjacent to the interpolation picture element by respective interpolation coefficients calculated from the image signal components for the adjacent original picture elements. The density vector at the interpolation picture element on the original image represented is calculated, distances of the respective adjacent original picture elements from a segment perpendicular to the density vector are calculated, the interpolation coefficient is corrected to be smaller as the density vector and/or the distance of the original picture element from the segment becomes larger, and the interpolating operation is carried out on the basis of the corrected interpolation coefficient.
