Abstract: An image display device includes an approach situation information acquirer that acquires approach situation information indicating approach of at least part of a customer's body to a shelf on which a plurality of items are displayed and indicating, when there is the approach, a position of the approach on the shelf at each time; an associator that associates the approach situation information with one item of the plurality of items according to the position indicated by the approach situation information; an index value calculator that calculates an index value relating to the customer's behavior on the basis of information indicating the item associated with the approach situation information; and a display unit that displays the index value calculated by the index value calculator together with an image of the item on the basis of the association made by the associator.

Abstract: An output control device includes a control unit configured to cause an output device to output first information including a plurality of types of information, and an information determination unit configured to identify a type to be presented to a person and determine second information of the identified type on the basis of the first information output by the output device and a response of the person to the first information, wherein the control unit is configured to cause the output device or another output device to output the second information determined by the information determination unit.

Abstract: The purpose of the present invention is to correct more accurate marketing information. A flow line display system of the present invention includes image-capturing unit, information operation device and display unit. The image-capturing unit captures an image. The information operation device detects an object from the image and identifies a flow line of the object, an orientation of the object, and a time related to the orientation. The display unit displays the orientation of the object and the time related to the orientation together with the flow line of the object.

Abstract: A behavior analysis device includes an approach information acquisition unit configured to acquire approach information indicating whether or not a person has approached a shelf on which a plurality of goods are displayed, a determination unit configured to determine as stockout information a position of a stockout item which is out of stock among the plurality of goods displayed on the shelf and a stockout of the stockout item, and an analysis unit configured to perform behavior analysis of the person on the basis of the approach information and the stockout information.

Abstract: An output control device includes a determination unit configured to determine whether or not a person is a specific person, a processing unit configured to acquire position information of the person, and an output control unit configured to cause a first output device located in the vicinity of the person to output information according to the person on the basis of personal information about the person determined to be the specific person by the determination unit and the position information acquired by the processing unit, wherein the output control unit is configured to cause a second output device to output the information output by the first output device in continuation with the output of the first output device if the person has moved from the vicinity of the first output device to the vicinity of the second output device.

Abstract: The position management device includes: a calculation unit that gives identification on an object being monitored to the object being monitored cyclically imaged, and calculates positional information of the object from an image of the object; a storage unit that associates the identification and an imaging time with the positional information, and stores these items; and a comparison unit that compares, with respect to the object, an absolute value of a difference between the positional information as of a current time and the positional information as of each of the imaging times one and two cycle(s) prior to the current time, as stored in the storage unit, with a predetermined reference value, and outputs the positional information as of the current time if the absolute value for at least one of the imaging times is less than the reference value.

Abstract: Disclosed is a position management device and the like which allow for high precision calculation of the positional information on an object being monitored from an image taken by a monitoring camera.
