デオカメラ装置。[Claims for Utility Model Registration] A video camera body capable of external synchronization control, and a memory into which a captured video signal supplied from the video camera body is written based on the synchronization signal and read out at a timing synchronized with a reference video signal. a control comprising: a phase comparison means for comparing a frame phase and a line phase of the captured video signal and a reference video signal; and a synchronization control signal forming means for forming a synchronization control signal based on a comparison output by the phase comparison means. What is claimed is: 1. A video camera apparatus comprising: a video camera unit, wherein a synchronization control signal is supplied from the control unit to the video camera body to perform synchronization control of captured video signals.
