1. An image processing device for performing correction processing on original image data generated by an image-capturing element configured to receive light with a plurality of pixels through a color filter including segments of a red color and at least one complementary color, the image processing device comprising a processing circuitry being configured to perform operations including:
converting the original image data into primary color-based image data represented in a primary color-based color space;
acquiring a statistical value of a plurality of pieces of pixel data corresponding to the plurality of pixels from the primary color-based image data;
calculating a correction parameter by using the statistical value; and
correcting the original image data based on the correction parameter,
wherein the correcting comprises a first correction processing and a second correction processing, the second correction processing being performed subsequently to the first correction processing, and
in the second correction processing, corrected image data generated in the first correction processing is corrected.
