An output control apparatus includes circuitry configured to acquire image data of a plurality of target objects captured at a site by an image capture device as captured image data; detect the plurality of target objects included in the captured image data; estimate a recognition level of an observing person on the detected plurality of target objects; identify a specific target object having lower recognition level among the detected plurality of target objects based on the estimated recognition level; and output screen-display image data including additional information set for the identified specific target object having lower recognition level, the screen-display image data generated for the acquired captured image data.
