PROBLEM TO BE SOLVED: To extract a featured value for precisely recognizing various photographing parts of a wide range from a head to bones of extremities with respect to a radiation image. SOLUTION: This processor has a signal change extracting means 30 for detecting the amount of radiation transmitted through an object and detecting signal change with its neighboring pixel concerning an optional pixel on the radiation image corresponding to the detected amount, a pattern detecting means 40 for detecting one or plural patterns from the space distribution and the intensity distribution of the signal change obtained by the signal change extracting means, and a featured value extracting means 50 for extracting the featured value based on a pattern detected by the pattern detecting means. |
