Abstract: A beam diameter varying portion varies a first beam diameter of a measuring beam incident on an optical portion to a second beam diameter larger than the first beam diameter. An adjustment portion adjusts a condensing position of the measuring beam on the optical portion based on intensity information of a return beam from a position of an inspection object with the first beam diameter.

A condensing position can be adjusted in a relatively short time because the measuring beam small in beam diameter is used, and a combined beam can be acquired with high transverse resolution because the measuring beam large in beam diameter is used.

Abstract: An HMD (10a) generates region information indicating a region having, as an axis, a line which passes through the position of the HMD (10a) and that of a wireless I/F (105a). The HMD acquires position information of each of wireless I/Fs of other image processing apparatuses (11b, 11c). The HMD determines if the position indicated by the acquired position information is included in the region indicated by the region information. The HMD selects one of the wireless I/F (105a) and other wireless I/Fs as a wireless communication partner according to the determination result, and receives images via wireless communication with the selected wireless I/F.
