Abstract

A radiographic imaging device including: a sensor portion that generates an output signal according to an irradiated amount of irradiated radiation; a detector that based on the output signal detects a radiation irradiation start of radiation irradiated from a radiation source during capture of a radiographic image; a noise data generation means that, based on an output signal from the sensor portion in a non-irradiation state of radiation from the radiation source, generates noise data relating to noise incorporated in the output signal; a controller that controls detection sensitivity to radiation irradiation start in the detector according to a degree of variation in noise level expressed by the noise data; and an imaging unit that captures the radiographic image after radiation irradiation start has been detected by the detector.

First claim

What is claimed is:

1. A method of performing radiographic imaging comprising:
generating an output signal according to an irradiated amount of irradiated radiation using a sensor portion;
using a detector to detect, based on the output signal, a radiation irradiation start of radiation irradiated from a radiation source during capture of a radiographic image;
generating noise data with a noise data generator that, based on an output signal from the sensor portion in a non-ir…
