Imaging information processing apparatus, X-ray imaging apparatus, X-ray imaging system, control method, and program for causing computer to execute control method

A radiography apparatus, comprising:

• a detection circuit configured to detect that irradiation of radiation is started;
• an X-ray sensor including a plurality of photoelectric converter elements and configured to obtain an X-ray image in response to detection by the detection circuit;
• and
• a driving circuit configured to drive the X-ray sensor;
• wherein the detection circuit changes a condition for detecting the start of irradiation of radiation such that the start of irradiation of radiation is less likely to be detected in a case where the start of irradiation of radiation is detected on the basis of electric charges generated by the photoelectric converter elements in a first period than in a case where the start of irradiation of radiation is detected on the basis of electric charges generated by the photoelectric converter elements in a second period.

An information processing apparatus comprising:

• a communication circuit configured to communicate with an X-ray imaging apparatus, the X-ray imaging apparatus including a detection unit configured to detect irradiation of radiation by photoelectric conversion and an X-ray sensor configured to obtain an X-ray image in response to the detection by the detection unit;
• and a control circuit,
• the control circuit being configured to perform
• a discriminating process of discriminating between a valid imaging period and an invalid imaging period, and
• a display control process of causing a display unit to display an icon for checking that the X-ray image is transferred from the X-ray imaging apparatus in response to the detection unit detecting irradiation of radiation in a period determined to be the invalid imaging period.

An information processing method comprising:
