An image control method that is executable to cause a computer (40, 60) to perform a process, the process comprising: displaying a plurality of items of selection option information on a display device; receiving, using the display device, a selection operation by a user of an item of the selection option information, and storing, in a first storage section, the selected item of the selection option information in association with a timing at which the selection operation for the selected item of the selection option information is received; detecting, using a detection device, detection information indicating at least one of a state of an area at which the display device is disposed or a state of a user present in the area at which the display device is disposed, and storing, in a second storage section, the detection information in association with time information indicating a time at which the detection information is detected; extracting, from the second storage section, time information that is associated with detection information indicating that at least one of the area or the user is in a predetermined state; identifying an item of the selection option information stored at the first storage section in association with a timing that corresponds to the extracted time information from the second storage section; associating a specific change timing with the identified item of the selection option information, the change timing being a duration that elapses starting from the start of display of the item of selection option information on the display device, and storing the identified item of the selection option information and the associated change timing in a third storage section; determining whether or not a change timing of any of the plurality of items of the selection option information displayed on the display device has arrived, by referencing the third storage section; effecting control so as to display, on the display device, the item of the selection option information that has been determined such that the change timing thereof has arrived using a different display mode from that of other displayed items of the selection option information; and effecting control so as to return the one of the other displayed items of the selection option information currently using the different display mode to its original display mode. displaying a plurality of items of selection option information on a display device; receiving, using the display device, a selection operation by a user of an item of the selection option information, and storing, in a first storage section, the selected item of the selection option information in association with a timing at which the selection operation for the selected item of the selection option information is received; detecting, using a detection device, detection information indicating at least one of a state of an area at which the display device is disposed or a state of a user present in the area at which the display device is disposed, and storing, in a second storage section, the detection information in association with time information indicating a time at which the detection information is detected; extracting, from the second storage section, time information that is associated with detection information indicating that at least one of the area or the user is in a predetermined state; identifying an item of the selection option information stored at the first storage section in association with a timing that corresponds to the extracted time information from the second storage section; associating a specific change timing with the identified item of the selection option information, the change timing being a duration that elapses starting from the start of display of the item of selection option information on the display device, and storing the identified item of the selection option information and the associated change timing in a third storage section; determining whether or not a change timing of any of the plurality of items of the selection option information displayed on the display device has arrived, by referencing the third storage section; effecting control so as to display, on the display device, the item of the selection option information that has been determined such that the change timing thereof has arrived using a different display mode from that of other displayed items of the selection option information; and effecting control so as to return the one of the other displayed items of the selection option information currently using the different display mode to its original display mode.
