摘要： In the improved thermal recording method in which image data supplied from an image data supply source are subjected to specified image processing jobs and in which a thermal head is driven in accordance with the processed image data so as to perform thermal recording, image processing jobs are performed in a specified order such that sharpness correction and tone correction are followed by shading correction and correction of resistance values which, in turn are followed by compensation for temperature elevation, provided that calculation treatment of respective values of the image data for the compensation for temperature elevation is performed either prior to or after either one of the corrections that are performed subsequent to the tone correction. It is preferred that black ratio correction and/or load variation correction are also performed after the shading correction and the correction of resistance values, and prior to the compensation for temperature elevation. The improved thermal recording apparatus is used to carry out the thermal recording method described above. According to these apparatus and method, high quality images can be recorded consistently.

摘要： Offset correction based on offset correction data is performed on radiographic image data that have been read out from a radiation image detector, and the offset correction data are updated. In the offset correction method, correction data for low-frequency components and correction data for high-frequency components, as the offset correction data, are generated based on offset image data that have been read out from the radiation image detector while the radiation image detector is not irradiated with radiation. Further, the correction data for low-frequency components and the correction data for high-frequency components are separately updated.

摘要： A first leakage current value output from each signal line is stored in a storage unit, with a charge corresponding to an emitted radiation being held in a radiographic image detector, when the radiation is uniformly emitted to the radiographic image detector. A second leakage current value is acquired which is output from each signal line, with a charge corresponding to the radiation dose being held in the radiographic image detector, when the radiation passing through an object is emitted to the radiographic image detector. When the first and second leakage current values are equal to each other for each line corresponding to each signal line, all pixels on the line are determined to belong to a background area (lines A and C). When the second leakage current value is smaller than the first leakage current value and larger than a predetermined value, it is determined that there are the object areas and the background areas on the line (lines B, D, and E), and the total number of pixels in the background area on the line is calculated from the ratio of the first leakage current value to the second leakage current value. In this way, the distribution of the object area and the background area in the image which is held in the radiographic image detector when the radiation passing through the object is emitted is estimated before the reading of the image from the radiographic image detector is completed.

摘要： Correction is performed on the pixel values of a plurality of defective pixels forming a defective area of an image representing a subject image. The defective area is an area corresponding to a defective portion of a detector. A plurality of weighted normal pixel values are obtained by weighting the pixel value of each of normal pixels adjacent to the periphery of the defective area for each pair of a correction-target defective pixel and each of the normal pixels using a weighting coefficient. The weighting coefficient becomes smaller as a distance between the defective pixel and the normal pixel becomes longer. Then, an average value of the plurality of weighted normal pixel values is calculated, and the pixel value of the correction-target defective pixel is corrected using the calculated average value. This process is performed on each of the defective pixels.

摘要： A residual image signal, which represents a residual image remaining on a stimulable phosphor sheet having been subjected to an erasing operation, is acquired. A radiation image of an object is then recorded on the stimulable phosphor sheet, from which the residual image signal has been detected. A radiation image signal, which represents the radiation image of the object, is then acquired, the thus acquired radiation image signal containing a residual image signal, which represents the residual image. The residual image signal is subtracted from the radiation image signal, and a radiation image signal, which represents the radiation image of the object and which is free from the residual image signal, is acquired.

摘要： A stimulable phosphor sheet is conveyed in a sub-scanning direction while projecting the stimulating light in the main scanning direction, an exposed area on the stimulable phosphor sheet is imaged on each light receiving portion of a line sensor which is formed by causing the same to correspond to a sub-scanning direction, the stimulated light emitted from the exposed area is photoelectrically converted by each light receiving portion to obtain a partial image signal, and an image signal representing the radiation image recorded on the stimulable phosphor sheet is obtained by summing the partial image signals obtained by the light receiving portions in each light receiving line arranged in the sub-scanning direction. Each partial image signal is obtained by converting the stimulated light received when the same area on the stimulable phosphor sheet is imaged on the light receiving portions which are arranged in the sub-scanning direction at different timings.
