To facilitate setting of a parameter at the time of generating an inspection image from an image acquired by using a photometric stereo principle. A photometric processing part generates an inspection image based on a plurality of luminance images acquired by a camera. A display control part and a display part switch and display the luminance image and the inspection image, or simultaneously display these images. An inspection tool setting part adjusts a control parameter of the camera and a control parameter of an illumination apparatus. Further, when the control parameter is adjusted, the display control part updates the image being displayed on the display part to an image where the control parameter after the change has been reflected.
