IMAGE PROCESSING APPPARATUS AND CONTROL METHOD THEREOF

摘要

An image processing apparatus according to an embodiment of the present invention includes: a signal receiving unit which includes at least one connector which is connected to the plug of an external device and is able to receive a signal from the external device through the plug which is connected to the connector; a signal processing unit which processes a signal which is received in the signal receiving unit according to a predetermined process; a storage unit in which a predetermined test signal is stored; and a control unit which transmits the test signal which is stored in the storage unit when electrically connecting a first terminal and a second terminal to the first terminal about any one connector which includes the first terminal and the second terminal, and determines and checks the signal transmission state of the connector about the signal processing unit based on whether the preset signal feature of the test signal which is fed back through the second terminal is changed or not.
