X-ray image generating module, X-ray imaging system and method for generating X-ray image

The present invention relates to an x-ray detecting panel, an x-ray image creating module, an x-ray photographing apparatus and an x-ray image creating method. An x-ray image creating module includes a plurality of pixel groups having a plurality of pixels and to detect an x-ray to convert the x-ray into an electric signal. Each of the pixel groups includes an x-ray detecting panel to detect x-rays of mutually different energy bands; and an image processing unit to read out data for one part of an x-ray image from an electric signal of at least one of the pixel groups, calculating prediction data of another part of the x-ray image based on the plurality of read data, and combining the read data and the prediction data with each other to create an x-ray image corresponding to the x-ray in a specific energy band.
