摘要： A superior graphic processing device is provided that performs parallel and fast edge function processing for coverage calculations during an anti-aliasing process. The edge function for each sub-pixel of a pixel can be described separately for the base edge function Bef concerning pixel coordinates, and the sub-edge function Sef concerning sub-pixel references, and when the sum of the values for the edge functions Bef and Sef is substituted as a variable for evaluation function LineIOcheck, whether a sub-pixel is located above, below, or on an edge line can be determined. &Dgr;x

摘要： A plurality of image signals are obtained, which represent a radiation image of a single object or radiation images of the single object, and which have different frequency characteristics, each of the image signals being made up of a series of image signal components. The image signal components of the plurality of the image signals, which image signal components represent corresponding picture elements, are weighted with predetermined weight factors. The weighted image signal components of the plurality of the image signals, which image signal components represent corresponding picture elements, are added to one another, and an addition signal is thereby obtained. The value of the weight factor with respect to the frequency components, which have a low signal-to-noise ratio, is rendered smaller than the value of the weight factor with respect to the frequency components, which have a high signal-to-noise ratio, in accordance with the frequency characteristics of each of the image signals.

摘要： A stimulable phosphor sheet, on which a radiation image has been stored, is exposed to stimulating rays, which cause it to emit light in proportion to the amount of energy stored thereon during its exposure to radiation. The light, which is emitted from the front surface of the stimulable phosphor sheet, and the light, which is emitted from the back surface of the stimulable phosphor sheet, are respectively detected. An image readout from the front surface of the stimulable phosphor sheet and an image readout from the back surface of the stimulable phosphor sheet are thus carried out independently of each other, two image signals being thereby obtained. An abnormal state in the image readout from each of the front and back surfaces of the stimulable phosphor sheet is detected. In cases where an abnormal state has been detected in the image readout from the front or back surface of the stimulable phosphor sheet, the image readout from the surface side of the stimulable phosphor sheet, on which side the abnormal state in the image readout has been detected, is ceased.

Predetermined operation processing is performed on the plurality of the received original image signals in the operation processing device to obtain an operation-processed image signal. Also, at least one original image signal, which is among the plurality of the original image signals, is transferred to an image output device. Image outputting is performed with the image output device and in accordance with the one original image signal having been transferred. After the operation-processed image signal has been obtained from the predetermined operation processing, the operation-processed image signal is fed into the image output device, and image outputting is performed with the image output device and in accordance with the received operation-processed image signal.

摘要： Stimulating rays produced by a line light source are linearly irradiated onto an area of a stimulable phosphor sheet, on which a radiation image has been stored. Light, which is emitted from the linear area of the sheet exposed to the linear stimulating rays, is received and photoelectrically converted by a line sensor. Outputs of the line sensor are corrected in accordance with variation in sensitivity among a plurality of pixel regions of the line sensor, which pixel regions are arrayed along the length direction of the linear area of the stimulable phosphor sheet.

摘要： Upon transferring two image signals to an output apparatus in an image transfer system, the amount of data to be transferred can be reduced. In an image signal output apparatus, subtraction signal generating means generates a subtraction signal from a front-side image signal and rearside image signal, and the subtraction signal as well as either the front-side image signal or the rearside image signal are transferred to an operation and display terminal. When the front-side image signal and the subtraction signal are transferred, the operation and display terminal restores the rearside image signal by carrying out an operation using the subtraction signal and the front-side image signal having been transferred thereto. The front-side image signal and the rearside image signal are similar, and the amount of the subtraction signal is smaller than the amount of the rearside image signal, which results in reduction in the amount of data to be transferred.
