    • An image processing apparatus including: at least one connector including at least one connection pin configured to be connected to an external device; an interface which interfaces transmission of signals to the connection pin through a first wiring formed between the interface and the connection pin; a switching unit which is switched on to transmit a signal through a second wiring which is formed differently from the first wiring to feedback the signal from the connection pin to the interface; a controller which controls the switching unit to allow the feedback of the signal through the second wiring to transmit a preset test signal from the interface to the first wiring at the time of inspecting a signal transmission state of the connection pin and the first wiring, and determines the signal transmission state based on a change of the test signal feedbacked to the interface through the second wiring.
    • 一种图像处理设备,包括:至少一个连接器,包括被配置为连接到外部设备的至少一个连接引脚; 接口,其通过形成在接口和连接引脚之间的第一布线将信号传输到连接引脚; 开关单元,其被接通以通过不同于第一布线形成的第二布线发送信号,以将信号从连接引脚反馈到接口; 控制器,其在检查所述连接引脚和所述第一布线的信号传输状态时,控制所述切换单元允许通过所述第二布线的所述信号的反馈,将来自所述接口的预设测试信号传输到所述第一布线;以及 基于通过第二布线反馈到接口的测试信号的变化来确定信号传输状态。
