    摘要: An image acquisition unit acquires an X-ray image obtained by irradiating a subject with an X-ray and a dark image obtained without irradiating the X-ray. A dark correction mode input unit inputs a dark correction mode for correcting the X-ray image using the dark image. A control unit sets a noise suppression parameter according to the dark correction mode received from the dark correction mode input unit. A dark correction unit corrects the X-ray image based on dark image according to the dark correction mode received from the dark correction mode input unit. A noise suppression unit performs noise suppression processing on the X-ray image corrected by the dark correction unit, using the noise suppression parameter received from the control unit.

    摘要: An image processing apparatus for performing tone conversion on an image imaged by an X-ray imaging system extracts a reference region that is to serve as a reference for the image, and, if there is a change in the image, performs tone conversion so as to suppress variation in contrast resulting from the change in the image in the extracted reference region, and so as to reflect variation in the contrast in the remaining region.
