Image data processing device, image data processing method, image data processing program, and imaging system

An image data processing device that processes image data captured by an imaging device including an optical system which spectrally separates incident light into a plurality of wavelengths, polarizes light with the spectrally separated wavelengths in a specific direction, and emits the polarized light and an imaging element including a plurality of pixel sets each of which includes different types of polarizers, the image data processing device comprising:

• a processor configured to perform:
• a process of acquiring the image data;
• a process of detecting a pixel whose pixel value is out of a predetermined range as an abnormal pixel from the acquired image data;
• a process of 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
• a process of generating images of the spectrally separated wavelengths from the image data in which the pixel value of the abnormal pixel has been corrected in a case in which the abnormal pixel is detected,
• wherein the process of detecting the abnormal pixel includes:
• a process of detecting a pixel set including the abnormal pixel;
• and
• a process of specifying the abnormal pixel from the detected pixel set.
