摘要： 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.

摘要： An operation of an iris filter is carried out on an original image signal representing an image, and the degree of centralization of gradients of the original image signal with respect to a picture element is thereby calculated, each of picture elements constituting the image being taken as the picture element. An image portion, which is associated with a high degree of centralization, in the image is detected in accordance with the calculated degree of centralization. Image emphasis processing is then selectively carried out on the detected image portion. Alternatively, a morphology operation is carried out on an original image signal Dorg by using a multiply structure element Bi and a scale factor &lgr;, and a morphology signal Dmor is thereby obtained. The morphology signal Dmor represents whether each of picture elements constituting the image is or is not the one corresponding to an image portion, at which the original image signal Dorg fluctuates in a spatially narrower range than the multiply structure element Bi. Image emphasis processing is then carried out on the original image signal Dorg and in accordance with the morphology signal Dmor.

摘要： An apparatus for computer aided diagnosis of images comprises an entire area image memory for storing an entire area image signal representing a radiation image of an object, and a prospective abnormal pattern detecting device for detecting a prospective abnormal pattern in the radiation image in accordance with the entire area image signal. A judgment device makes a judgment as to the presence or absence of the prospective abnormal pattern in accordance with the results of the detection of the prospective abnormal pattern carried out by the prospective abnormal pattern detecting device. In cases where the judgment device has judged that the prospective abnormal pattern is present, a local area extracting device extracts a local area limited image signal corresponding to a local area containing the prospective abnormal pattern from the entire area image signal having been stored in the entire area image memory. A local area limited image displaying device displays the image of the local area in accordance with the local area limited image signal, which has been extracted by the local area extracting device. An entire area image displaying device displays the entire area of the radiation image of the object in accordance with the entire area image signal.

摘要： At least one kind of image input modality and at least one kind of image information output device are connected to an image processing system. At least one kind of image input modality, which is among connected image input modalities, includes a plurality of image information input apparatuses having different input device characteristics. The image processing system comprises a standardization device for carrying out transform processing on image information such that, in every case where the image information has been received from one image information input apparatus, which is among the plurality of the image information input apparatuses, the received image information may be transformed into standard image information, which does not depend upon the input device characteristics of the one image information input apparatus and depends upon standard device characteristics having been set previously for the image input modality including the one image information input apparatus.

摘要： A filtering process and an interpolating operation process are carried out in steps on an original image signal and, in the respective steps, a plurality of unsharp image signals are formed, which represent images having the same size as the size of the original image and have different frequency characteristics. Band-limited image signals are formed from the unsharp image signals and the original image signal, restricted by conversion, and integrated. An integration signal composed of predetermined frequency components of the original image signal is thereby formed. The frequency emphasis processing is carried out by multiplying the integration signal by an emphasis coefficient, and adding the resulting product to the original image signal. The dynamic range compressing process is carried out by converting a difference signal, which is obtained by subtracting the integration signal from the original image signal, and adding the converted difference signal to the original image signal. An artifact is thereby prevented from occurring at a region in the vicinity of an edge.
