1. An inspection support system for erroneous attachment, the inspection support system comprising:
a controller including a processor and a memory communicably connected with the processor; and
an imaging device communicably connected with the controller and configured to capture an image that represents a state in which multiple components are attached to each other, wherein
the controller is configured to
convert a color space of the image captured by the imaging device into an HSV color space,
create a comparative image on a basis of hue and saturation in the HSV color space,
determine whether the multiple components are each a correct component and whether the multiple components are attached to each other in a correct manner by comparing the comparative image with a correct image, the correct image being based on the hue and the saturation and representing a state in which the multiple components are attached to each other correctly, and
detect the erroneous attachment of at least one of the multiple components, in a case where the erroneous attachment detector determines that the at least one of the multiple components is not the correct component and/or that the at least one of the multiple components is not attached in the correct manner, and
wherein the comparative image is constituted by only hue (H) and saturation (S) in the HSV color space of the image and omits value (V) in the HSV color space of the image.
