摘要： An image data processing device processes image data captured by an imaging device that includes an optical system which spectrally separates incident light and polarizes light with the spectrally separated wavelengths, and emits the polarized light in a specific direction and an imaging element including a plurality of pixel sets each of which includes different types of polarizers. The image data processing device performs processes of: acquiring the image data; detecting a pixel whose pixel value is out of a predetermined range as an abnormal pixel from the acquired image data; correcting a pixel value of the abnormal pixel on the basis of pixel values of peripheral pixels in a case in which the abnormal pixel is detected; and generating images of the spectrally separated wavelengths from the image data in which the pixel value of the abnormal pixel has been corrected when the abnormal pixel is detected.
