An image output apparatus that is capable of switching between a normal status and a low power status in which power consumption is lower than that in the normal status, the image output apparatus comprising: an interface for acquiring an image signal; a signal detector configured to detect a signal at the interface, the signal including a connection signal that reflects that an external device is connected to the interface; a power status switching controller; and a power status switching setting storage; wherein the signal detector is configured to generate a detection signal based on the signal detected at the interface and report the detection signal to the power status switching controller, wherein the detection signal includes a connection detection signal that reflects that the signal detector detects the connection signal, and in the event that the image signal is acquired at the interface, the signal detector is further configured to generate an input detection signal that reflects that the signal detector detects the image signal, and to report the input detection signal to the power status switching controller; the power status switching setting storage being configured to store a power status switching setting, the power status switching setting being set to one of a first setting and a second setting, the first setting indicating that the apparatus is to be switched from the low power status to the normal status if the connection signal is reported by the signal detector and the second setting indicating that even if the connection signal is reported by the signal detector, the apparatus is not to be switched from the low power status to the normal status unless the input detection signal is also reported by the signal detector; the power status switching controller being configured to switch the apparatus from the low power status to the normal status based on the power status switching setting stored in the power status switching setting storage. an interface for acquiring an image signal; a signal detector configured to detect a signal at the interface, the signal including a connection signal that reflects that an external device is connected to the interface; a power status switching controller; and a power status switching setting storage; wherein the signal detector is configured to generate a detection signal based on the signal detected at the interface and report the detection signal to the power status switching controller, wherein the detection signal includes a connection detection signal that reflects that the signal detector detects the connection signal, and in the event that the image signal is acquired at the interface, the signal detector is further configured to generate an input detection signal that reflects that the signal detector detects the image signal, and to report the input detection signal to the power status switching controller; the power status switching setting storage being configured to store a power status switching setting, the power status switching setting being set to one of a first setting and a second setting, the first setting indicating that the apparatus is to be switched from the low power status to the normal status if the connection signal is reported by the signal detector and the second setting indicating that even if the connection signal is reported by the signal detector, the apparatus is not to be switched from the low power status to the normal status unless the input detection signal is also reported by the signal detector; the power status switching controller being configured to switch the apparatus from the low power status to the normal status based on the power status switching setting stored in the power status switching setting storage.
