Radiographic-image capturing device and radiographic-image capturing system

A radiographic-image capturing device comprising:

• a detecting unit provided with a plurality of scanning lines and a plurality of signal lines arranged so as to intersect with each other, and a plurality of radiation detection elements arranged two-dimensionally each of which is arranged at each of areas partitioned by the plurality of scanning lines and the plurality of signal lines;
• a read-out circuit which reads out electric charges from the radiation detection elements via the signal lines, converts the electric charge to an electric signal for each of the radiation detection elements, and outputs the electric signal as image data;
• and
• a compression section which performs compression processing to image data for each of the radiation detection elements,
• wherein the compression section prepares difference data by calculating difference between image data of the radiation detection elements adjoining to each other for each of the image data outputted from a plurality of radiation detection elements connected to a same signal line, and performs compression processing to the difference data.

• a thinned-out data preparing section for thinning and, from the image data, abstracting image data per scanning line unit and preparing thinned-out data;
• and
• a compression section which performs compression processing to the thinned-out data,
• wherein the compression section performs compression processing to thinned-out data adjoining in a direction of the signal line, or performs compression processing to difference data for the thinned-out data adjoining in the direction of the signal line by calculating difference for the thinned-out data adjoining in the direction of the signal line and generating the difference data.
