acquiring first information representing resolution of the second image and second information representing a position of the third image relative to the second image on the image supplier;
converting the first coordinates into second coordinates in a coordinate system of the first image, which represent a position in the first image, based on the first information and the second information;
transmitting the second coordinates to the image supplier;
receiving, by a display apparatus, the image signal; and
estimating, by the display apparatus, the first information based on the image signal.
