Abstract

An object is to realize a control system capable of displaying a display screen of a television receiver (control target device) including a high-resolution display device and quickly performing processes such as a movement of the display, a change in a display magnification, a change in a display angle, and the like through intuitive operations. In the control system (1000), by specifying one point of a display screen on a second display unit (23) of a remote control device (2), that is, acquiring one-point specifying information, it is possible to perform a display position changing process (movement process) using absolute position coordinates. Accordingly, for example, when a control target device (1) serves as a television receiver (control target device) including the high-resolution display device, the second display unit (23) of the remote control device is able to display a display screen of the control target device and quickly perform movement of the display through an intuitive operation.
