1. An X-ray fluoroscopic imaging apparatus comprising:
an imaging unit including an X-ray source for irradiating a subject with X-rays and an X-ray detector for detecting X-rays irradiated from the X-ray source;
an X-ray image acquisition unit configured to acquire an X-ray image captured by the imaging unit;
a target distribution learning identification unit configured to output distribution of a target appearing in the X-ray image using a trained learning model;
an image quality improvement processing unit configured to perform image quality improvement processing for improving image quality of the X-ray image; and
a display unit configured to display the X-ray image,
wherein the image quality improvement processing unit is configured to switch between a first image processing mode for performing the image quality improvement processing on the X-ray image using a learning identification result by the target distribution learning identification unit and a second image processing mode for performing the image improvement processing mode on the X-ray image without using the learning identification result.
