Radiation video processing device, radiation video capturing device, radiation video capturing system, radiation video processing method and program storage medium

A radiographic video processing method, comprising:

• detecting whether or not a video image formed from a plurality of frames is being captured using a radiation detector in which a plurality of pixels are disposed in a matrix formation, each pixel including a sensor portion that generates charges according to irradiated radiation and a switching element that reads charges generated at the sensor portion, by switching the switching elements ON and OFF to read the charges and converting the read charges to voltage, and detecting whether or not a number of the pixels, from which charges are combined and read by the switching elements included in adjacent pixels, has been increased;
• and
• controlling such that, if it is detected that the number of pixels has been increased, the gradation signals expressing the charges distributed in a higher density range than that for frames subsequent to a predetermined frame are used as image data, from a frame at a time of the increase up until the predetermined frame.

A non-transitory storage medium storing a program that causes a computer to execute radiographic video processing, the processing comprising:

• detecting whether or not a video image formed from a plurality of frames is being captured using a radiation detector in which a plurality of pixels are disposed in a matrix formation, each pixel including a sensor portion that generates charges according to irradiated radiation and a switching element that reads charges generated at the sensor portion, by switching the switching elements ON and OFF to read the charges and converting the read charges to voltage, and detecting whether or not a number of the pixels, from which charges are combined and read by the switching elements included in adjacent pixels, has been increased;
• and
• controlling such that, if it is detected that the number of pixels has been increased, the gradation signals expressing the charges distributed in a higher density range than that for frames subsequent to a predetermined frame are used as image data, from a frame at a time of the increase up until the predetermined frame.
