20090238454 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND IMAGE PROCESSING PROGRAM - An image processing apparatus includes a red eye candidate detecting section, a gold eye candidate detecting section, and a red eye-gold eye-correcting section. Herein, the red eye candidate detecting section detects a red eye candidate, which is an area of a color included in a color range of a predetermined red color, from image by using a detecting threshold value differentiating a red eye from a gold eye. The gold eye candidate detecting section detects a gold eye, which is an area of a color included in a color range of a predetermined gold color that is not overlapped with a color range of the predetermined red color, from image by using the detecting threshold value. The red eye-gold eye-correcting section performs a predetermined red eye correcting process to a red eye candidate detected by a red eye candidate detecting section, and performs a predetermined gold eye correcting process, which is different from a predetermined red eye correcting process, to a gold eye candidate detected by a gold eye candidate detecting section. | 09-24-2009 |

20100177960 | IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND IMAGE PROCESSING PROGRAM - An image processing apparatus includes a red eye candidate detecting section, a red eye-gold eye separating section, a gold eye converting section, and a red eye correcting section. Herein, the red eye candidate detecting section detects a red eye candidate included in images. The red eye-gold eye separating section judges whether a red eye candidate detected by the red eye candidate detecting section is either red eye or a gold eye respectively specified in a predetermined color range. The gold eye converting section converts a color of the red eye candidate, which was judged as red eye by the red eye-gold eye separating section, into a color, which is judged as a red eye by the red eye-gold eye separating section. The red eye correcting section performs a red eye correction to a color of the red eye candidate converted by the gold eye converting section. | 07-15-2010 |
20110075811 | Radiation detection device, imaging control device, radiation imaging system, and self diagnostic method of radiation detection device - In a cassette-type X-ray detection device, an X-ray detector and a self diagnostic circuit are contained in a cassette casing. When the cassette-type X-ray detection device gets a shock, the self diagnostic circuit is actuated. The self diagnostic circuit reads out from the X-ray detector an offset image being a dark current image, and analyzes the offset image. The self diagnostic circuit finds out an abnormal portion from the offset image, and diagnoses whether the X-ray detector is available, unavailable, or partly available based on the size and position of the abnormal portion. Shock detection and a diagnostic result are displayed on a touch panel provided in the cassette casing, and sent to a console device via a communication unit. | 03-31-2011 |
20120091352 | RADIATION DETECTOR, RADIOGRAPHIC IMAGE CAPTURING SYSTEM, RADIATION DETECTION METHOD, AND RADIATION DETECTION PROGRAM STORAGE MEDIUM - A radiation detector includes an image data detecting unit that detects, as radiographic image data, charge information corresponding to applied radiation; a control unit that determines that radiation has been applied if a read value of the detected charge information is equal to or greater than a threshold value and controls the image data detecting unit to acquire radiographic image data corresponding to radiation that has passed through a subject; and a changing unit that changes the threshold value in accordance with temperature data of the image data detecting unit. | 04-19-2012 |
20120091353 | RADIATION DETECTOR, RADIOGRAPHIC IMAGE CAPTURING SYSTEM, RADIATION DETECTION METHOD, RADIATION DETECTION PROGRAM STORAGE MEDIUM, AND CONTROLLER - A radiation detector includes a detection unit, a detection control unit, an image analyzing unit and a determination unit. The detection unit detects radiographic image data by plural pixels that convert applied radiation into electrical signals and store the electrical signals. The detection control unit controls the detection unit so as to determine that radiation has been applied if a read value obtained by reading the electric signals stored in the plural pixels is equal to or greater than a threshold value, and acquire radiographic image data corresponding to radiation that has passed through a subject. The image analyzing unit performs an image analysis with respect to the radiographic image if the read value is equal to or greater than the threshold value. The determination unit determines based on the result of the image analysis whether or not the radiographic image has been detected at an intended timing. | 04-19-2012 |
20120093291 | RADIOGRAPHIC IMAGING DEVICE, RADIOGRAPHIC IMAGING SYSTEM, COMPUTER-READABLE MEDIUM STORING RADIOGRAPHIC IMAGING PROGRAM, AND RADIOGRAPHIC IMAGING METHOD - The present invention provides a radiographic imaging device including: a detecting section that detects a dose of radiation that has been irradiated when imaging a radiographic image corresponding to irradiated radiation; and a determining section that determines whether the radiographic image is a valid image on the basis of the dose of radiation that has been detected by the detecting section. | 04-19-2012 |
20120305791 | RADIOGRAPHIC IMAGE DETECTOR AND CONTROL METHOD THEREFOR - A flat panel detector has an imaging area, in which pixels are arrayed in a matrix and signal lines for reading out electric signals from the pixels are provided, to detect an image of a subject from x-rays which are incident on the imaging area after penetrating the subject. Detective elements are arranged in the imaging area, to output electric signals corresponding to incident x-rays. Based on previously stored sensitivity data on the detective elements, high-sensitivity elements are selected from among the detective elements. The start of radiation and the end of radiation of x-rays toward the imaging area are detected by monitoring the electric signals from the selected high-sensitivity elements, to control operation of the imaging device on the basis of the detected start and end of radiation. | 12-06-2012 |
20120305792 | RADIOGRAPHIC IMAGE DETECTOR AND CONTROL METHOD THEREFOR - An x-ray image detector monitors the intensity of incident x-rays to detect an end of radiation from an x-ray source when the x-ray intensity decreases to a threshold level or less. The x-ray intensity gets down to zero with a variable time lag from the start of decreasing, called radiation wave tail. Depending on the gradient of declivity in time curve of the decreasing x-ray intensity, calculated at the time when the end of radiation is detected, the x-ray image detector decides a delay time from the end-of-radiation detection time to a reading start time to start reading signal charges from the image detector. Thus, the reading start time may be adjusted to the point when the x-ray intensity gets down to zero, which will improve S/N ratio and prevent shading artifacts. | 12-06-2012 |
