Abstract: When image data are compressed, a degree of image quality degradation can be recognized. At the time of compressing the image data, compression information is added as tag information in a file header of the image data. In this manner, by referring to the compression information, compression history of the compressed image data can be understood, and a degree of image quality degradation of the image data obtained by decompressing the compressed image data can be known.

Abstract: In an image processing method for obtaining a processed image signal from an original image signal representing an original image having a certain picture element density, a plurality of intermediate image signals which are different in frequency band are made on the basis of the original image signal. A plurality of transformed image signals are obtained by carrying out a transformation processing on the respective intermediate image signals on the basis of respective transformation functions, and a processed image signal is obtained from the transformed image signals. The transformation functions are defined by determining transformation function defining parameters for the transformation functions on the basis of the picture element density of the original image.

Abstract: To provide a PTFE laminated article having a sufficient adhesive strength and a PTFE backing sheet having a low permeability, in which a specific weight of a PTFE sheet can be maintained high. A specific weight of the PTFE sheet is maintained at 2.175 or more by carrying out thermo-fusing of the PTFE sheet and a film or sheet of heat-meltable resin such as PFA after interposing a layer of PTFE fine particles between them or by carrying out treatment for preventing a rapid temperature lowering after the thermo-fusing without interposing the layer of PTFE fine particles.

Abstract: A steam turbine plant partially utilizes a hydrocarbon fuel such as an LNG as a fuel to improve the efficiency of the plant. A steam turbine plant includes a boiler, a steam turbine, a feedwater system, and a superheating combustor. The boiler generates steam, and the steam turbine is driven by the steam generated in the boiler. The feedwater system recovers the steam exhausted from the steam turbine and supplies the steam to the boiler as a feedwater. The superheating combustor is provided between the boiler and the steam turbine, wherein fuel originated from hydrocarbon fuel and oxidizer are mixed with the steam generated in the boiler and combusted in the superheating combustor to increase the temperature of the steam.

Abstract: Disclosed herein is a method of storing or transferring an image along with an image-processing parameter for processing the image. When storing or transferring a second image for storage or transfer which has a second resolution for storage or transfer differing from a reference resolution, a reference image-processing parameter set according to a reference resolution image having the reference resolution is corrected based on a difference between the reference resolution and the second resolution, so that it becomes a second parameter corresponding to the second image. The second parameter obtained by the correction is stored or transferred along with the second image.

Abstract: A locking/unlocking mechanism for an operable cover of a body such as a printer to lock and unlock the body with a single operation and to a printer having an operable cover and a locking/unlocking mechanism for the operable cover. The operable cover is locked when a cover side engaging part in the cover engages a body-side engaging part in the body. The printer has a cover opening button 10 which is depressed to a first operating position 10B, causing a locking lever 14 in the locking/unlocking mechanism 11 to slide from a locked position 14A to an unlocked position 14B. The locking lever has an engaging channel 15 which releases the cover-side engaging part 12 of the operable cover 4, thereby disengaging the operable cover 4 but not opening it.

Abstract: A linear stimulating ray source produces stimulating rays and linearly irradiates them to a portion of a stimulable phosphor sheet, on which a radiation image has been stored. A photoelectric read-out system divides light, which is emitted from the portion of a front surface of the stimulable phosphor sheet exposed to the stimulating rays and/or the portion of a back surface of the stimulable phosphor sheet corresponding to the portion of the front surface exposed to the stimulating rays, into picture elements along a length direction of the portion exposed to the stimulating rays, and photoelectrically reads out the divided picture elements by arraying them in a two-dimensional form. A scanning system moves the stimulable phosphor sheet with respect to the linear stimulating ray source and the photoelectric read-out system and in a direction, which is approximately normal to the length direction of the portion exposed to the stimulating rays.

Abstract: Output-size information G1 and reference-resolution information G0 are input to a zoom-rate section. The zoom-rate section derives zoom-rates M1 and M2, based on the output-size information G1 and the reference-resolution information G0. A reconstruction section reconstructs an image at the resolution level corresponding to the specified zoom-rate M1. A parameter-setting section derives an image-processing parameter K1 suitable for the resolution level of a reconstructed-image signal S1, based on the zoom-rate M1, reference-resolution information G0, and reference-processing parameter K0, and sets the derived parameter K1 to the image-processing section. The image-processing section obtains a processed-image signal S2 by performing image processing, using the image-processing parameter K1. A zoom-processing section performs a zoom process on the processed-image signal S2, using the zoom rate M2.

Abstract: Band-limited image signals representing images, each of which is of one of different frequency bands, are formed from an original image signal representing an original image. A pixel vector at each of pixels in each of the band-limited images, which are represented by the band-limited image signals, is calculated. A noise component and an edge component of each of the band-limited images are separated in accordance with the calculated pixel vector. Smoothing processing for the noise component and/or enhancement processing for the edge component is performed on each of the band-limited image signals to obtain a processed band-limited image signal. A processed image signal is then obtained in accordance with the thus obtained processed band-limited image signals. The image processing is thus performed such that noise components contained in the image become imperceptible, and such that a structure pattern contained in the image becomes perceptible.

Abstract: Similarity is judged with accuracy between images. Two image data sets are input to input means and metadata sets attached thereto are extracted. The metadata sets include characteristic information on objects included in images represented by the two image data sets. Object evaluation means calculates evaluation values representing similarity between the objects, based on the characteristic information. Image evaluation means calculates a similarity value between the two images, based on the evaluation values. Image classification means classifies the image data sets according to the similarity value and stores the image data sets in storage means together with a classification result.

Abstract: Image data transferred progressively can be processed efficiently. Image data are transferred progressively from an image server to a display terminal via a network. Images are progressively displayed on a monitor and a user views the images reproduced progressively on the monitor. The user inputs an interruption of transfer by using input means when a image has a sufficient resolution for reading. In response, the image server interrupts progressive transfer of the image data. In this manner, data at a resolution unnecessary for reading are not transferred after the interruption, and time necessary for data transfer can be shortened. In this manner, an efficient diagnosis can be carried out.
