An electronic endoscope apparatus has an endoscope unit and an image processing unit. The endoscope unit is configured to be inserted into the subject's body cavity and has a first communication control unit configured to perform bidirectional communication with the image processing unit via a signal line in time-division fashion. The image processing unit has a second communication control unit configured to perform bidirectional communication with the endoscope unit via the signal line in time-division fashion. The second communication control unit transmits a signal to the endoscope unit during a period in which no signals are transmitted to it from the first communication control unit.
