TV CAMERA APPARATUS, AND CAMERA CONTROL UNIT AND CAMERA HEAD FOR USE IN THE APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a head-separated type TV camera apparatus, a camera control unit and camera head for use in the apparatus capable of achieving a no-adjustment of a circuit to improve clock jitters and compensate phase-delay caused by a phase-delay factor of transmission path, for example, a length of a cable. SOLUTION: In the TV camera apparatus, a camera control unit sends a clock signal 6a' to a camera head via a camera cable 4 from a camera control unit, the camera head sends back a received clock signal 4a' to the camera control unit via the cable 4 and the camera control unit samples video charge output in response to the sent-back clock signal 4b'.
