Abstract
A video camera having a control target which can be controlled by an external control apparatus via communication, and a control method of the video camera. In first memory of the video camera, predetermined standard control data for the control target is stored. When communication is established with an external control apparatus, control data from the external control apparatus is temporarily stored in second memory, and it is determined whether or not a communication error has occurred in the communication with the external control apparatus. If no error is detected in the determination, the control data stored in the second memory is stored in the third memory, but if an error is detected, the control data stored in the second memory is deleted, and the control target is controlled based on the control data stored in the third memory or predetermined standard data stored in the first memory.
