A cryopump system includes: a plurality of cryopumps; a plurality of compressor units arranged to operate in parallel in accordance with a control output, respectively, to supply refrigerant gas to the plurality of cryopumps; and a cryopump controller operative to determine the control output for each of the plurality of compressor units. The diffuse illumination arises from varying the diffusion angle of light generated by an LED system. Then, when an SPM synthesizing section generates a stereo image from the object image signal, a partition area setting section sets the luminance level of a partition are on the basis of the exposure information on the parallel object images, the partition area is a median strip used to arrange monocular images of the parallel object images away from each other. Each compartment at least partially encloses the skin-penetration member, the spring actuator, and the needle hub of a respective sampling site.
