<p>PURPOSE: A photographing apparatus, a lens unit, and a control method thereof are provided to perform an AF operation of the improved response rate even through the photographing apparatus performs TV AF control. CONSTITUTION: A photographing device (106) performs charge accumulation and generates an image signal through synchronization with a vertical synchronization signal. A control unit (116) generates control information about each of optical members (101-105) and performs communication with the lens unit through synchronization with the vertical synchronization signal. The control unit performs first communication through synchronization with the vertical synchronization signal and performs second communication through synchronization with the next vertical synchronization signal before performing the next first communication. [Reference numerals] (107) Control unit; (108) Camera signal processing circuit; (109) Monitor display; (110) Recording unit; (111) Zoom driving source; (112) Focus driving source; (113) TVAF gate; (114) TVAF signal processing circuit; (115) Lens microcomputer; (116) Camera microcomputer; (117) Lens unit; (118) Camera unit; (119) Aperture driving source; (120) Signal processing circuit</p> |
