RADIATION IMAGING APPARATUS AND METHOD OF CONTROLLING THE SAME, RADIATION IMAGE PROCESSING APPARATUS AND METHOD THEREOF, AND COMPUTER-READABLE STORAGE MEDIUM |
| 摘要 |
A radiation imaging apparatus acquires a radiation image from radiation detected by a radiation detection unit, corrects a first pixel that is a correction target in the radiation image by referring to a second pixel other than the first pixel, calculates an evaluation value that evaluates an increase in a noise level caused by correcting the first pixel, and performs processing of reducing the noise level for the first pixel after the correction based on the calculated evaluation value. |

1. A radiation imaging apparatus comprising:
an acquisition unit configured to acquire a radiation image from radiation detected by a radiation detection unit; a correction unit configured to correct a first pixel that is a correction target in the radiation image by referring to a second pixel other than the first pixel; a calculation unit configured to calculate an evaluation value that evaluates an increase in a noise level caused when the first pixel is corrected by the correction unit; and a reduction unit configured to perform processing of reducing the noise level for the first pixel after the correction based on the evaluation value calculated by the calculation unit. |
