PROBLEM TO BE SOLVED: To provide an image processing device capable of acquiring highly accurate normal information from an image of a subject.SOLUTION: An image processing device acquires normal information of a subject using an imaging device having imaging means and lighting means. The image processing device comprises: radiating means that causes the lighting means to radiate light to the subject, at a wavelength in which the intensity of reflected light from the subject becomes equal to or greater than a predetermined value on the basis of the reflection characteristic of the surface of the subject generating means that causes the imaging means to record the reflected light from the subject in sensitivity corresponding to the wavelength, and thereby generates image data and calculating means that calculates the normal information of the surface of the subject, on the basis of at least one of the reflection characteristic, the wavelength and the sensitivity, in addition to the image data generated by the generating means.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】被写体の画像から高精度な法線情報を取得することができる画像処理装置を提供すること。【解決手段】撮像手段と照明手段とを有する撮像装置を用いて、被写体の法線情報を取得する画像処理装置であって、画像処理装置は、前記被写体の表面の反射特性に基づいて前記被写体からの反射光の強度が所定値以上になる波長で、前記照明手段から前記被写体に光を照射させる照射手段と、前記被写体からの反射光を、前記波長に応じた感度で前記撮像手段に記録させて画像データを生成させる生成手段と、前記反射特性、前記波長および前記感度の少なくとも1つと、前記生成手段により生成される画像データとに基づいて、前記被写体の表面の法線情報を算出する算出手段と、を備える。【選択図】 図2
