1. A display control apparatus comprising:
at least one memory that is configured to store instructions; and
at least one processor that is configured to execute the instructions to:
detect a first situation using audio data including a sound around a display device or detect a second situation using image data including surroundings of the display device, the first situation being a situation in which target information being displayed by the display device can be viewed by a person other than a specific person, the second situation being a situation in which the target information being displayed by the display device can be captured by a camera; and
change an output state of the target information in the display device in response to detection of the first situation or the second situation,
wherein a change of the output state is processing of stopping output of the target information or processing of reducing visibility of the target information as compared with visibility before the change,
wherein the display device displays screen data that is transmitted via a network, and
wherein the change of the output state of the target information includes cutting off transmission of the screen data or adding change to the screen data in a relay device configured to relay transmission of the screen data from the device being a transmission source.
