PROBLEM TO BE SOLVED: To provide a technical method which reduces noises within a radiation image data to allow use of the data in a wide range of signal levels and allows a single image processing platform to be used in a wide range of X ray uses. SOLUTION: An embodiment of the technical method, which provides a system and a method for obtaining a low noise measurement in terms of a wide range of analog signal intensities, executes a low gain measurement for the input pixel electric charges which are distributed into two feedback condensers (46, 48) for uniting to provide a relatively low integral gain, and then removes one of the condensers from a feedback loop and distributes the electric charge again in the other condenser to execute a high gain measurement.
