In a measurement support device according to an aspect, since information indicating a movement trajectory of a spot when an imaging distance is changed is displayed, it is easy to move the spot to be in the vicinity of a measurement target by changing the imaging distance by operating a head and an imaging unit forward or backward, and the measurement can be swiftly and easily performed. In addition, since an indicator figure (circular marker) having a size set according to the position of the spot is displayed, distance measurement is not necessary, the configuration is simple, and the processing load is low. Further, since the indicator figure and the information indicating the trajectory are displayed in the vicinity of the spot, the difference between the spot position and the position of the indicator figure is small and thus the indicator figure is accurate as an indicator, and since the indicator figure is not displayed in a wide range, the processing load is low.
