Display apparatus and control method

A control method, comprising:

• capturing a moving image of a user in a predetermined imaging space with respect to a direction in which an image is displayed by a display unit;
• analyzing the captured moving image and calculating a position of the user in the predetermined imaging space, wherein the analyzing:
• determines whether the user should be guided to an optimum viewing position in the predetermined imaging space, and
• determines whether the user does not need to be guided to the optimum viewing position in the predetermined imaging space,
• the determining being made based on the analysis of the captured moving image,
• causing the display unit to perform display to display information to guide the user to the optimum viewing position when the calculated position of the user is at a position other than the optimum viewing position.

A display apparatus, comprising:

• an imaging unit configured to capture an image of at least one user in a predetermined imaging space with respect to a display direction of a display unit;
• an image analyzer configured to detect the at least one user in the captured image, to calculate a direction of the at least one user with respect to an optical axis of the imaging unit, and to calculate a viewing position to which the at least one user should be guided;
• at least one sensor configured to detect a distance between the at least one user and the display apparatus;
• a display controller configured to cause the display unit to display information to guide the at least one user to the viewing position by checking the calculated direction and the detected distance,
• wherein the image analyzer is further configured to make a determination of whether the at least one user should be guided to the viewing position, by checking the calculated direction of the at least one user and the detected distance between the at least one user and the display apparatus.
