PROBLEM TO BE SOLVED: To provide a technique that can acquire transmission images of high image quality where uneven density is suppressed.SOLUTION: The information processing apparatus detects radiation that is radiated from a radiation generation part and transmits a specimen in a detection part, and performs processing for obtained value distributions that are detected by a detection part. The information processing apparatus includes a value distribution acquisition unit for acquiring the value distributions, and a corrector for correcting the value distributions according to the distributions of value corresponding to a given chart part where the degree by which the radiation transmits is known out of the value distributions.COPYRIGHT: (C)2012,JPO&INPIT【課題】濃度ムラが抑制された高画質の透過像を取得することができる技術を提供する。【解決手段】放射線発生部から放射され、検体を透過する放射線を検出部で検出して得られた値分布に対して処理を行う情報処理装置であって、値分布を取得する値分布取得手段と、該値分布のうち、放射線が透過する度合いが既知である所定のチャート部に対応する値の分布に応じて、該値分布を補正する補正手段と、を備える。【選択図】図1
