An endoscopic system includes a speckle reduction unit which is reduce speckle generated on an observed portion by light that has coherence, a controller which controls an operation of the speckle reduction unit and a plurality of observation modes including a speckle observation mode of observing the observed portion based on the speckle generated on the observed portion by the light. The controller controls the operation of the speckle reduction unit in accordance with the observation modes such that the speckle reduction unit does not reduce the speckle in the speckle observation mode and the speckle reduction unit reduces the speckle in the observation modes other than the speckle observation mode.
