摘要： A digital image signal, which represents values of picture elements arrayed along X and Y directions of an image, is subjected to operation processing carried out with the formulaQ'=Qorg+.beta.(Qorg-Qus),wherein Qorg represents the original image signal representing each picture element, Qus represents an unsharp mask signal corresponding to super-low frequency with respect to the picture element, and .beta. represents an emphasis coefficient. The image signal obtained from the operation processing is fed into a reproducing apparatus, which reproduces an image by operations for scanning along X and Y directions. The operation processing is carried out with respect to the X and Y directions, under characteristics varying for different directions, and in accordance with a difference between responses of the reproducing apparatus along the X and Y directions. Final levels of sharpness of a visible image, which is reproduced by the reproducing apparatus, along the X and Y directions are thereby adjusted to be approximately equal to each other.

摘要： In a monochromatic image display system, the number of tone levels which can be expressed is multiplied. As a display device, a liquid crystal panel 40 which can express each picture element 41 of a monochromatic image by three cells 41a, 41b and 41c is employed. A tone number conversion processing means 20 carries out a tone number conversion processing on an input original image signal Sorig according to the maximum number of tone levels which can be expressed by the liquid crystal panel 40, thereby obtaining a monochromatic image signal So. Luminance of the monochromatic image signal So is allotted to the cells 41a, 41b and 41c. Time modulation is carried out on each cell by a time modulation means 12 which can express four tone levels (but tone level 0) so that each cell outputs allotted luminance. In this manner, the liquid crystal panel 40 can express thirteen tone levels (4×3+1=13) in total (tone level 0 inclusive).

摘要： 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.

摘要： The method of gradation correction of input image data to be displayed on an image display apparatus converts to logarithmic data first characteristic values which represent the display characteristics inherent in the image display apparatus and second characteristic values which represent the desired gradation to be eventually realized with the image display apparatus, respectively, and optionally interpolating both the logarithmic data, constructs a gradation correction table based on both the logarithmic data of the first characteristic values and the logarithmic data of the second characteristic values and performs gradation correction on the input image data to the image display apparatus using the gradation correction table. The image display system displays on the image display apparatus the thus corrected image data on which the gradation correction is performed by implementing the method. The method and system are capable of producing a smooth enough correction LUT (look-up table) to allow gradation correction to be performed in such a way that the image display apparatus will eventually provide the intended display characteristics. Therefore, the system can display a high quality image that has no defects such as artifacts.

摘要： A gradation converting process is carried out on an image signal and in accordance with a predetermined gradation converting table, and a visible image, which is represented by an image signal having been obtained from the gradation converting process, is displayed on an image displaying device. In the gradation converting process, the amount of depletion of luminance of the image displaying device is detected, and the gradation converting table is corrected in accordance with the detected amount of depletion of luminance such that the depletion of luminance of the image displaying device may be compensated for. A visible image having good image quality is thereby displayed on the image displaying device regardless of depletion of luminance of the image displaying device.
