1. An image processing device, comprising:
circuitry configured to:
receive a vegetation index value set image in which a vegetation index value is set as a pixel value;
generate a corrected image of the vegetation index value set image, wherein the vegetation index value indicates a plant activity;
calculate, for each of pixels that constitute the vegetation index value set image, a first average pixel value of a pixel and neighboring pixels;
generate an averaged image in which average pixel values calculated for the each of the pixels that constitute the vegetation index value set image are set;
binarize a difference image between the vegetation index value set image and the averaged image based on a threshold;
generate a binarized image based on the binarized difference image; and
generate, as the corrected image of the vegetation index value set image, a multiplication image based on multiplication of the vegetation index value set image and the binarized image.
