Radiological image detection apparatus

A portable radiological image detection apparatus comprising:

• an imaging unit that includes a plurality of pixels arranged in a two-dimensional array which detect a radiation and convert the radiation to an electrical signal, and acquires radiological image data based on the electrical signal output from each pixel;
• a storage unit that stores correction data for correcting the radiological image data acquired by the imaging unit while the imaging unit is exposed to the radiation;
• a correction data generating unit that generates new correction data based on dark image data acquired by the imaging unit while the imaging unit is not exposed to the radiation and updates the correction data stored in the storage unit by the new correction data;
• a correction unit that performs a correction process for the radiological image data using the correction data stored in the storage unit;
• a disturbance detection unit that detects a disturbance acting when the imaging unit acquires the dark image data;
• and
• a determination unit that determines whether the updating of the correction data stored in the storage unit by the correction data generating unit is permitted, or whether the acquisition of the dark image data by the imaging unit is permitted, based on the detection result of the disturbance detection unit.
