IMAGE PROCESSOR AND X-RAY IMAGE PROCESSOR

摘要

PROBLEM TO BE SOLVED: To reduce X-ray exposure dose of a subject while securing sufficient visibility of an X-ray image.SOLUTION: An image processor in one embodiment includes an acquisition part and a correction part. The acquisition part acquires a first X-ray image radiographed with a first radiographing method and a second X-ray image radiographed with a second radiographing method different from the first radiographing method. The correction part corrects a luminance value of the second X-ray image so that the noise amount of the second X-ray image comes close to the noise amount of the first X-ray image.
