The present invention provides a digital X-ray image system, an X-ray irradiation controlling device, and a method therefor in order to find out a main-shot condition for obtaining a main-shot radiograph signal on the basis of a radiograph signal (for example, a reference pixel value) outputted in response to a pre-shot condition using specific characteristics between a radiograph signal (pixel value) and a radiograph condition. The X-ray irradiation controlling device includes: a pre-shot radiography condition determiner determining a radiography condition; a reference pixel value acquirer acquiring a reference pixel value from a pre-shot radiograph obtained under the pre-shot radiography condition; an interrelation acquirer acquiring interrelation between a radiography condition and a radiograph signal on the basis of the reference pixel value; and a main-shot radiography condition determiner determining a main-shot radiography condition using the interrelation.
