A mounting device that, during movement of a mounting head, captures a first image that includes components that are collected in the mounting head and first fiducial marks, captures a second image that includes the components that are collected in the mounting head and second fiducial marks, and generates an image of the components that are collected in the mounting head using the first image and the second image based on the positional relationship of the first fiducial marks and the second fiducial marks. At this time, the mounting device captures the first image after the components and the first fiducial marks enter the same imaging range prior to the second fiducial marks entering the imaging range, and after that, captures the second image after the first fiducial marks come out from the imaging range and the components and the second fiducial marks enter the same imaging range.
