摘要： An image signal is read out by use of a stimulable phosphor sheet having a layer of stimulable phosphor which emits stimulated emission in proportion to the stored energy of radiation upon exposure to stimulating light and a solid image sensor having a photoconductive material layer which exhibits electric conductivity upon exposure to the stimulated emission from the stimulable phosphor sheet. Stimulating light is caused to scan a stimulable phosphor sheet which has been exposed to radiation and has stored an image, the photoconductive material layer is caused to be exposed to stimulated emission emitted from the stimulable phosphor sheet upon exposure to the stimulating light. Then electric charges generated in the photoconductive material layer upon exposure to the stimulated emission is detected by applying an electric field to the photoconductive material layer. The stimulable phosphor sheet has a layer of stimulable phosphor which is stimulated by stimulating light in a wavelength range of not shorter than 600 nm and emits stimulated emission in a wavelength range of not longer than 500 nm. The solid image sensor has a photoconductive material layer whose major component is a-Se, and the electric field is such as to generate an avalanche amplification effect in the photoconductive material layer.

摘要： A connector is capable of selectively connecting different types of cards. The connector has a first connector portion having a first contact for connection to a first card, and a second connector portion having a second contact for connection to a second card. The first contact and the first card are connected together in a fitting/removal direction, while, the second contact and the second card are connected together in a direction crossing the fitting/removal direction. When the first contact and the first card are connected together, the second contact is prevented from contacting the first card. When the second contact and the second card are connected together, the first contact is prevented from contacting the second card.

摘要： Stimulating light is projected by a stimulating light projector onto the stimulable phosphor sheet to expose a linear portion of the stimulable phosphor sheet extending in a main scanning direction to the stimulating light and stimulated emission emitted from the stimulable phosphor sheet upon exposure to the stimulating light is detected by a line sensor extending in the main scanning direction with an imaging optical system intervening between the stimulable phosphor sheet and the line sensor or with the line sensor held in the vicinity of the stimulable phosphor sheet. The stimulable phosphor sheet is fixed in a read-out position, and the radiation image is read out while the stimulating light projector and the line sensor are being moved relatively to the fixed stimulable phosphor sheet in a sub-scanning direction intersecting the main scanning direction.

摘要： Two image signals representing radiation image information are acquired from opposite surfaces of a stimulable phosphor sheet, on which the radiation image information has been stored. Operation processing is performed on the two image signals in accordance with predetermined operation processing parameters, and an operation-processed image signal representing the radiation image information is obtained. A ratio between read-out sensitivities with respect to the opposite surface sides of the sheet and/or the predetermined operation processing parameters with respect to at least either one surface side of the sheet are controlled in accordance with read-out conditions employed at the time of the image signal acquisition.

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.

摘要： White light and excitation light are applied to an internal body part. An electronic endoscope captures a normal image of the internal body part irradiated with the white light, and a special image of autofluorescence emitted from living body tissue of the internal body part irradiated with the excitation light. An object distance detector detects an object distance between a CCD and an inspection area of the internal body part based on the normal image. A binning processing section applies a binning process to the special image. There are two types of binning processes, i.e. an intensity adjustment process and a resolution adjustment process. In the intensity adjustment process, the binning number is increased with increase in the object distance. In the resolution adjustment process, the binning number is decreased with increase in the object distance. Which process to perform is determined by operation on a processing type selector.
