1. A display system comprising:
a display device that displays an image to be visually recognized by a user and that includes a first geomagnetic sensor detecting a posture of the display device; and
an information processing device that connects to the display device, and that includes:
an operation screen display part displaying an operation image;
a second geomagnetic sensor detecting a posture of the information processing device; and
a display control part (i)storing a predetermined position between the display device and the information processing device that is set by the user, (ii)obtaining a relative position between the display device and the information processing device based on the posture of the display device and the posture of the information processing device, (iii)determining whether the relative position between the display device and the information processing device is the predetermined position that is set by the user, and (iv)changing a display mode of the display device in which a brightness of the image displayed on the display device is darker than a brightness of the operation image displayed on the operation screen display part of the information processing device when the relative position between the display device and the information processing device is the predetermined position that is set by the user.
