1. An image processing device, comprising:
a central processing unit (CPU) configured to calculate one of a band-corresponding gain or band-corresponding gain calculation parameters to match a first output value of a reference camera with a second output value of an adjustment camera that is a first multispectral camera, based on:
a reference machine band-corresponding pixel value that is a first pixel value within a specific band, wherein
the first pixel value is acquired based on the first output value of a first imaging element of the reference camera; and
an adjustment machine band-corresponding pixel value that is a second pixel value within the specific band, wherein
the second pixel value is acquired based on the second output value of a second imaging element of the adjustment camera.
