摘要： When carrying out further color balance adjustment processing on color-balance adjusted image data having been through color balance adjustment processing, processing performance of the further color balance adjustment processing is sufficiently used. In a digital camera, by carrying out processing such as first AWB processing and chroma enhancement processing on original image data obtained by photographing, output image data are obtained. The output image data are then input to a printer. In the printer, processing which is the inverse of processing carried out in processing means of the digital camera and inverse AWB processing which is the inverse of the first AWB processing is carried out on the output image data, and inverse AWB image data which can be regarded as the original image data are obtained. Processed image data are then obtained by carrying out second AWB processing different from the first AWB processing on the inverse AWB image data, and a print is generated by output means based on the processed image data.

摘要： Volume data (32) including slice images (30) captured by a CT apparatus (12) is transferred to an image server (14). A CPU (40) of the image server (14) allows a region recognizing section (46) to recognize a region of each slice image (30) included in the volume data (32). The recognized region is recorded in a tag area (36) of each slice image (30) as region information (36c). The CPU (40) references the region information (36c) of each slice image (30) and judges if the volume data (32) includes regions or not. If the CPU (40) judges that the volume data (32) includes regions, an image compressing section (47) selects a common compression mode and compresses each slice image (30) in a common compression mode at a compression ratio.

摘要： Volume data formed of tomographic images (medical images) is stored in a storage unit of a data center. Recorded in a tag area of each tomographic image is site information indicating the site contained in each tomographic image. A data server of the data center reads the volume data from the storage unit in response to a transmission request from a medical facility. Then, the data server extracts from the volume data the tomographic images of the same site as designated by the transmission request. The data server transmits the extracted tomographic images to the medical facility which made the transmission request.

摘要： A method of restoring phase information using a phase-contrast method, which can improve estimated accuracy of a phase. This method is a method of restoring phase information by detecting intensity of radiation, and includes the steps of: (a) obtaining three first differential signals representing differentials between one image signal and another image signal based on four image signals obtained by detecting intensity of radiation on four planes and representing radiation image information respectively; (b) obtaining second and third differential signals representing differentials between image signals relative to two directions orthogonal to each other within the planes with respect to the three image signals; (c) obtaining a Laplacian of phase based on the three image signals and three sets of the first to third differential signals; and (d) performing inverse Laplacian operation on the Laplacian of phase so as to restore phase information.

摘要： Radiation is irradiated to an object, and the radiation, which carries image information of the object, is detected at a plurality of positions for image recording, which are set at different distances from the object, a plurality of radiation images of the object being thereby acquired. The acquisition of the radiation images is performed by use of a plurality of two-dimensional detectors, such that the radiation, which carries the image information of the object, at a position for image recording, which is remote from the object, is detected with a two-dimensional detector having a sensitivity higher than the sensitivity of a two-dimensional detector for detecting the radiation at a position for image recording, which is close to the object.

摘要： Each of image signals representing radiation images of a single object is weighted with a weight factor. Signal components of the weighted image signals representing corresponding pixels in the radiation images are subtracted from each other, and a difference signal representing an image of a specific structure of the object is obtained. The weight factor is set for each pixel in each radiation image and in accordance with a difference between logarithmic values of radiation doses with respect to corresponding pixels in the radiation images, or in accordance with a logarithmic value of a ratio between the radiation doses with respect to the corresponding pixels in the radiation images.
