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
摘要翻译：提供了一种优越的图形处理装置，其在抗混叠处理期间执行用于覆盖计算的并行和快速边缘功能处理。可以针对像素坐标的基本边缘函数Bef和关于子像素参考的子边缘函数Sef，以及边缘函数Bef的值之和分别描述像素的每个子像素的边缘函数并且Sef被替代为评估函数LineIOcheck的变量，可以确定子像素是否位于边缘线上方，下方或边缘线上。 DELTAx << x和DELTAy << y被建立，子边缘函数Sef的值远小于基本边缘函数Bef的值。当相对于一个相对较大的Bef处理单元设置多个相对较小的Sef处理单元时，可以设计集成在小区域中并具有相同覆盖计算能力的LSI。此外，Bef计算和多个Sef计算可以并行执行。

摘要： A radiation image read-out apparatus includes a condenser optical system which converges stimulated emission emitted from a radiation image convertor panel upon exposure to stimulating light. A photodetector receives the stimulated emission converged by the condenser optical system and has a sensitivity to light longer in wavelength than the stimulating light and a stimulating light cut filter is disposed in the optical path of the stimulated emission between the photodetector and the radiation image convertor panel to transmit the stimulated emission and to cut the stimulating light. A longer wavelength light cut filter which transmits the stimulated emission and attenuates the intensity of light components longer in wavelength than the stimulating light is provided in the optical path of the stimulated emission between the photodetector and the radiation image convertor panel.

摘要： An image recording sheet and a solid-state image detector are used. The sheet has a stimulable phosphor layer laminated on a base, and the solid-state image detector includes a photoconductive layer containing amorphous selenium as its main component and electrodes disposed on opposite sides of the photoconductive layer. An electric field is applied across the photoconductive layer so that avalanche amplification is obtained within the photoconductive layer. The sheet is scanned under the electric field with stimulating light of wavelength of about 600 nm, and photostimulated luminescence light of wavelength of about 400 nm emitted from the fluorescent layer is incident on the photoconductive layer via an optical guide and a stimulating light cut filter. Electric charge generated within the photoconductive layer is detected by a current detecting circuit, whereby a radiation image signal is obtained.

摘要： Initial image data having a pixel size smaller than a pixel size of a final image are obtained by using line sensors arranged in a main scan direction and a vertical scan direction, and the final image becomes of high quality by processing the initial image data to prevent the image from becoming uneven. Integration processing means carries out a first conversion process to convert the initial image data comprising signals detected by the line sensors into data for pixels divided in the main scan direction. The integration processing means carries out a second conversion process in which, whenever the data are obtained for three consecutive pixels in the main scan direction, the data are added to become data for one pixel of the final image. The data for the final image are then subjected to an equalization process such as dark current correction carried out by a correction means.

摘要： A stimulable phosphor sheet, on which radiation image information has been stored, is exposed to stimulating rays, which cause the stimulable phosphor sheet to emit light in proportion to the amount of energy stored thereon during its exposure to radiation. Light, which is emitted from opposite surfaces of the stimulable phosphor sheet when the stimulable phosphor sheet is exposed to the stimulating rays, is detected, and two original image signals representing the radiation image information are acquired. A read-out sensitivity and/or a read-out gain with respect to at least either one surface side of the stimulable phosphor sheet at the time of the image signal acquisition is controlled in accordance with specifications of the stimulable phosphor sheet.

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 emitted by the front surface of the stimulable phosphor sheet and the light emitted by the back surface of the stimulable phosphor sheet, are detected photoelectrically. The image signal components of the two image signals are subtracted from each other, which represent corresponding picture elements on the front and back surfaces of the stimulable phosphor sheet, difference values being thereby obtained. A judgment is made as to whether each of the difference values falls or does not fall within a predetermined range. In cases where a difference value is judged as being outside the predetermined range, it is determined that an abnormal signal component is contained in at least either one of the two image signals.
