Abstract
Video data recording using a plurality of video camera devices can be performed more conveniently than in the conventional technique. A video camera device working as a parent device has a signal sending/receiving function and a control function for the whole system, and a video camera device working as a child device has a signal sending/receiving function. The parent device sends synchronization data for time synchronization, and each child device performs a shooting operation in time synchronization with the parent device in accordance with the received synchronization data.
