More Information
Summary:A radiation image capturing apparatus that generates a plurality of frame images includes: radiation detecting devices that are arranged on a substrate and can generate electric charge; a voltage applying part that applies a reverse bias voltage to the radiation detecting devices; the data reading part that reads image data; and a noise detector that detects a voltage noise of the reverse bias voltage and outputs data, wherein the data reading part includes: an estimator that estimates an offset component; a noise data calculator that calculates noise data on the basis of the data output by the noise detector and the offset component estimated by the estimator; and an image correcting part that generates image data after correction by subtracting the noise data calculated by the noise data calculator.
