PROBLEM TO BE SOLVED: To provide a television lens data output device capable of automatically switching the update and output timing of lens data corresponding to the reception of a trigger signal outputted from the side of a camera. SOLUTION: When a trigger signal is outputted from a main body 12 of camera at the timing synchronized with a vertical synchronizing signal and the signal is received by a CPU 28 of a lens unit 14, the CPU 28 reads the respective positional information of the zoom position, the iris position, the focus position and the extender position at the timing synchronized with the trigger signal, calculates lens data such as the distortion or redistortion of a lens based on the information and outputs the obtd. lens data to the side of the camera. When the trigger signal is not inputted from the camera side, the output system of data is automatically switched so as to acquire and output the lens data at the timing determined by the CPU 28.
