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.

摘要： Systems and methods for easily and at high speed re-encrypting data recorded on a magnetic recording medium when the data is encrypted using an encryption key and the encryption key is changed. A track where effective user data is not recorded is set as a first reserved track, then data is read out from the first updating source track and decrypted using a first encryption key KEY 1, which is reencrypted using a second encryption key KEY 2 and recorded in the first reserved track, next, the first updating source track is set as a second reserved track, and a second updating source track is set, and the encryption key is updated by repeating these steps until all tracks to be subjected to the key updating processing have been subjected to the key updating processing.

摘要： Stimulating rays containing red light and infrared rays are reflected from a reference plate, which has reflection characteristics to the infrared rays approximately identical with those of a stimulable phosphor sheet, and which is free from characteristics of emitting light when being exposed to the stimulating rays. The stimulating rays reflected from the reference plate are received with a light receiving device via a cut-off filter for transmitting light emitted by the sheet and blocking the red light, and an infrared ray image signal representing the infrared ray components of the stimulating rays is acquired. The infrared ray image signal is subtracted from a radiation image signal representing a radiation image stored on the stimulable phosphor sheet.

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 radiation image read-out apparatus includes a plurality of radiation image convertor panels superposed one on another in a direction in which radiation passing through an object propagates. A separator separates the superposed radiation image convertor panels exposed to the radiation passing through the object from one another by moving in a parallel displacement and/or rotating about an axis on a plane parallel to the surfaces of the radiation image convertor panels one or more of the superposed radiation image convertor panels relatively to the others. A single detecting head detects stimulated emission emitted from each of the radiation image convertor panels separated by the separator.

摘要： Image processing, which is constituted of a plurality of processes, is carried out on a radiation image signal. An intermediate image signal obtained in at least one process, which is among the processes other than a last process in the plurality of the processes constituting the image processing, is stored on a predetermined storage medium. In cases where an abnormality occurred during the image processing, a process, in which the abnormality occurred, is discriminated quickly, and a cause of the abnormality is specified quickly.

摘要： In a radiation image read-out apparatus, a stimulable phosphor sheet storing thereon a radiation image is exposed to stimulating light and stimulated emission emitted from the stimulable phosphor sheet upon stimulation by the stimulating light is detected and an image signal representing the radiation image stored on the stimulable phosphor sheet is obtained by photoelectrically converting the stimulated emission. A read-out system includes an array of a plurality of read-out heads, each including a stimulating light source which projects the stimulating light onto the stimulable phosphor sheet and a photodetector which detects the stimulated emission. A conveyor system conveys the stimulable phosphor sheet and the read-out system relative to each other in a direction intersecting the direction of the array of the read-out heads.

摘要： Disclosed herein is a method of obtaining an image signal, comprising the steps of preparing an image recording sheet having a stimulable phosphor layer which emits photostimulated luminescent light in a quantity corresponding to stored energy when irradiated with stimulating light, scanning the image recording sheet in horizontal and vertical scanning directions with the stimulating light, and obtaining the image signal by detecting the photostimulated luminescent light emitted by the scanning, with a solid-state image detector having a photoconductor. The signal, output from the solid-state image detector when scanning a non-image region other than an image recording region on the image recording sheet with the stimulating light, is detected as a correction signal. A non-image component, contained in a signal output from the solid-state image detector when scanning the image recording region with the stimulating light, is suppressed with the correction signal.
