Abstract: One aspect of the present invention is an image display system including an image transmission device and a plurality of image display devices communicatively connected via a network. The image transmission device includes: an image converter configured to perform conversion into first image data which is image data representing a feature of an image on the basis of an input detected image which is an image displayed by an image display device of a connection target among the plurality of image display devices; and a communicator configured to transmit the first image data to the plurality of image display devices. Each of the plurality of image display devices includes: an image converter configured to convert a displayed image into second image data; an image data determiner configured to compare the first image data received from the image transmission device with the second image data and determine whether or not the first image data matches the second image data obtained by converting the displayed image; and a communicator configured to transmit connection permission information for connecting to the image transmission device to the image transmission device in accordance with a determination result of the image data determiner.

Abstract: A display control system includes a personal attribute information acquirer, a content specifier, and a display output. The personal attribute information acquirer acquires personal attribute information indicating an attribute of people present in an area including a vicinity of a display area for displaying video content based on a captured image of the area. The content specifier specifies target video content items, which are video content items to be displayed on the display area, based on the personal attribute information. The display output sets a plurality of screen areas in the display area based on the number of the target video content items and allocates and outputs the target video content items to the plurality of screen areas.
