1. A method for controlling an image display system, the method comprising:
displaying, by an image supplier, a second image contained in a first image;
transmitting, by the image supplier, an image signal based on a third image contained in the first image and different from the second image to a display apparatus;
displaying, by the display apparatus, a fourth image based on the image signal;
detecting, by the display apparatus, a position to which a pointing element is pointing on the fourth image;
identifying, by the display apparatus, first coordinates in a coordinate system of the fourth image, the first coordinates represent the position to which the pointing element is pointing in the fourth image;
acquiring, by the display apparatus, 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, by the display apparatus, 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, by the display apparatus, the second coordinates to the image supplier;
carrying out a process, by the image supplier, based on the second coordinates when the image supplier receives the second coordinates from the display apparatus;
receiving, by the display apparatus, the image signal; and
estimating, by the display apparatus, the first information based on the image signal.
