Claim:
1. A measurement apparatus comprising: a control unit configured to control an on/off state of illumination that does not contribute to acquisition of measurement data on the basis of an acquisition time period of the measurement data, wherein the measurement apparatus acquires the measurement data by scanning an object to be measured with a laser, detects, using a light detector, light reflected from the object, and further includes a data acquisition unit that generates an image on the basis of the measurement data, wherein the control unit turns on the illumination between acquisition of measurement data corresponding to a pixel of the generated image and acquisition of measurement data corresponding to another pixel of the generated image; wherein the control unit activates the data acquisition unit and deactivates the illumination in response to the acquisition time period of the measurement data being in an active state or an inactive state, respectively; wherein the control unit switches the on/off state of the illumination at a frequency of 50 Hz or more.
