7. The display control apparatus according to claim 1 , wherein the processor is configured to, in response to detection of a plurality of users from the detection information, obtain a gaze direction of each of the plurality of users based on the detection information, select a user who directs the user's gaze more to the display apparatus than another or other users as a user of interest based on the gaze direction of each user, and estimate the being time for the user of interest.

8. The display control apparatus according to claim 2 , wherein the processor is configured to, in response to detection of a plurality of users from the detection information, obtain a gaze direction of each of the plurality of users based on the detection information, select a user who directs the user's gaze more to the display apparatus than another or other users as a user of interest based on the gaze direction of each user, and estimate the being time for the user of interest.

9. The display control apparatus according to claim 3 , wherein the processor is configured to, in response to detection of a plurality of users from the detection information, obtain a gaze direction of each of the plurality of users based on the detection information, select a user who directs the user's gaze more to the display apparatus than another or other users as a user of interest based on the gaze direction of each user, and estimate the being time for the user of interest.

10. The display control apparatus according to claim 1 , wherein the processor is configured to, in response to detection of a plurality of users from the detection information, estimate an attribute of each of the plurality of users based on the detection information, select a user who has a same or similar attribute to an attribute of a user to which video data displayed on the display apparatus is targeted as a user of interest, and estimate the being time for the user of interest.

11. The display control apparatus according to claim 2 , wherein the processor is configured to, in response to detection of a plurality of users from the detection information, estimate an attribute of each of the plurality of users based on the detection information, select a user who has a same or similar attribute to an attribute of a user to which video data displayed on the display apparatus is targeted as a user of interest, and estimate the being time for the user of interest.

12. The display control apparatus according to claim 3 , wherein the processor is configured to, in response to detection of a plurality of users from the detection information, estimate an attribute of each of the plurality of users based on the detection information, select a user who has a same or similar attribute to an attribute of a user to which video data displayed on the display apparatus is targeted as a user of interest, and estimate the being time for the user of interest.
