Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method in which sensitivity distribution of an imaging element of an imaging device is measured by a simple way and calibration of an image display device is performed using the imaging device as a measuring apparatus.SOLUTION: Disclosed is a measurement device for measuring sensitivity distribution of an imaging element. This measurement device includes: acquisition means for acquiring a first image data and a second image data obtained by imaging an image of a subject by an imaging element under two conditions of different positions on the imaging element where the image of the subject is formed or different focal distances of the optical system capable of changing the focal distance forming the image of the subject on the imaging element; and calculation means for calculating the sensitivity distribution of the imaging element based on the first image data and the second image data. 【課題】簡易な方法で撮像装置の撮像素子の感度分布を測定し、撮像装置を測定器として用いて画像表示装置のキャリブレーションを行う方法を提供する。【解決手段】撮像素子の感度分布を測定する測定装置であって、被写体の像が形成される撮像素子上の位置、又は、被写体の像を撮像素子上に形成する合焦距離を変更可能な光学系の合焦距離が異なる、2つの撮像条件で前記撮像素子により被写体の像を撮像して得られる第1の画像データ及び第2の画像データを取得する取得手段と、前記第1の画像データと前記第2の画像データとに基づき前記撮像素子の感度分布を算出する算出手段と、を備える測定装置。【選択図】図19
