摘要： In energy subtraction processing, a high energy image signal SH and a low energy image signal SL are detected from two sets of stimulable phosphor sheets respectively carrying a high energy image and a low energy image of the same object stored thereon. A difference signal Ssub for forming an image of a specific structure of the object is calculated as Ssub=a.multidot.SH-b.multidot.SL+c. The value c is adjusted to a value calculated as c=m.multidot.Smax+n.multidot.Smin-a(m.multidot.SHmax+n.multidot.SHmin)+b(m.multidot.SLmax+n.multidot.SLmin) where Smax and Smin respectively denote the maximum density signal and the minimum density signal representing the maximum density and the minimum density desired in the subtraction image formed by the difference signal Ssub, SHmax and SHmin respectively denote the maximum value and the minimum value of the high energy image signal SH, SLmax and SLmin respectively denote the maximum value and the minimum value of the low energy image signal SL, and m and n respectively denote a constant including O.

摘要： By repeatedly adding items of picture element data representing an identical region of a serial picture element input which arrives serially in time, an improvement is effected in the S/N ratio of a periodic signal mixed in irregular, randomly occurring noise. A memory is provided for storing items of picture element data of one frame at storage locations corresponding to each of the picture elements. For each new item of picture element data that arrives, an item of picture element data of the same region accumulated and stored prior to said arrival is readout of the memory and added to the newly arrived data. The resulting sum is then written back into the memory at the same storage location. Thus, a single memory can be made to store picture data of enhanced S/N ratio merely by increasing slightly the bit storage capacity per data item in conformance with the number of times frames are accumulated.

摘要： A digital image display apparatus for converting a pixel value of medical digital image data such as MRI image data or CT image data into brightness in accordance with a display window including a window level and a window width of a display unit, determines the optimum window level and width for each image as follows. The apparatus obtains a histogram of pixel values from the digital image data and calculates brightness data of a pixel value having a highest frequency, brightness data of a pixel value at a boundary between a background and an image, area data of a portion having middle brightness within a display brightness range, area data of a portion having maximum brightness, and data indicating a ratio between an area of a portion having higher brightness than the middle brightness and an area of a portion having lower brightness than that obtained, when the digital image is to be displayed by a given display window on the basis of the histogram. The apparatus obtains image quality indicating clarity of the image displayed by the given window on the basis of the above data by using arithmetic operations or by using a neural network, thereby determining the optimum display window which provides a maximum image quality.

摘要： A processing device for changing magnification of image data applicable to a digital copier, a facsimile transceiver and other image processing apparatuses changes a magnification electrically, i.e., produces magnification-changed image data by estimating data with a changed magnification from data which are read with a 1 magnification. Nearby ones of original image data are sampled at a predetermined pitch and in synchronism with a data clock DCLK on the basis of a magnification R, which is specified on a 1% basis, so that magnification-changed image data Oij are computed and outputted in synchronism with the data clock. This realizes real-time processing, i.e., produces magnification-changed image data timed to the reading of an original image. Computations for MTF compensation are performed in matching relation to magnifications Rx and Ry, which respectively are specified in the main scanning and subscanning directions, so as to suppress deterioration of an image due to the change of magnification. Moreover, the computation of magnification-charged image data and that of MTF compensation in the main scanning direction are executed in a pair, and so are done the computation of magnification-changed image data and that of MTF (modulation transfer function) compensation in the subscanning direction. This ensures optimum MTF compensation in both of the main scanning and subscanning directions even if the magnifications Rx and Ry are different from each other, allowing a minimum of degradation of image quality with regard to the whole image.

摘要： A method for producing isostatically corrected gravity displays using available gravity data sets. The values of crustal density, density contrast between lower crust and mantle, and crustal thickness at sea level required for the Airy-Heiskanen equation are determined by analysis of the data set. Crustal density is determined by fractal analysis. Density contrast is determined by cross plotting Bouguer anomaly values versus elevation. Crustal thickness is determined by plotting power spectra of free-air gravity grids. The values are then used in the Airy-Heiskanen equation to provide the value of depth to crust-mantle boundary at each data point location in order to make accurate isostatic corrections and to produce accurate isostatically corrected displays.
