Abstract
In a TV control apparatus, a focus controller and a zoom controller are used to adjust a flange back focal length of a master lens. If a select switch switches the function of a focus controller from a focus lens control function to a master lens control function, a control signal is transmitted as a master lens control signal to a CPU from the focus controller. The master lens is controlled in accordance with the control signals. The focus lens is at a standstill during this period. The focus controller is also used as a master lens controller. If the zoom is at a wide-angle side, the focus controller is switched to the master lens controller, and if the zoom is at a telephoto side, the master lens controller is switched to the focus controller. If a flange back focal length adjustment switch is turned on and the zoom controller sets the zoom at the wide-angle side, the focus controller functions as a controller for adjusting the position of the master lens group. On the other hand, if the zoom is set at the telephoto side, the function of the focus controller is switched to the focus control function for adjusting the position of the focus lens group. This makes it possible to blur an image by operating the controller at hand.
