本发明提供一种能够在多个波长下获取透射波长位移少的图像的摄像装置及能够根据在多个波长下获取的透射波长位移少的图像来进行被摄体的测量的图像处理装置。成像于像高高的位置的高像高光束相对于光轴以较大的角度入射，因此透射波长位移会增加，但在第1方式所涉及的摄像装置中，第1光学系统使高像高光束以上光线与下光线平行的状态入射于第1滤光器及第2滤光器。因此，在第1、第2滤光器中，高像高光束的入射角度差导致的透射波长位移得到抑制，能够在多个波长下同时获取透射波长位移少的图像。 Provided are an imaging apparatus capable of acquiring an image having a small transmission wavelength shift at a plurality of wavelengths and an image processing apparatus capable of measuring a subject on the basis of an image which has a small transmission wavelength shift and which is acquired at a plurality of wavelengths. High image height rays imaged at a position of which an image height is high is incident at a large angle with respect to the optical axis. Therefore, the transmission wavelength shift increases. However, in the imaging apparatus according to the first aspect, the first optical system causes the high image height rays to be incident into the first optical filter and the second optical filter in a state where the upper ray and the lower ray are parallel.
