Patent ID: 7349013

Claim:
A camera system comprising: a lens device having: a variator lens means for performing a zooming operation; lens-side zoom operating means for operating said variator lens means; lens-side information output means for outputting first zoom operating information, which is received from said lens-side zoom operating means, and zoom position information on a zoom position of said variator lens means; lens-side information input means for receiving second zoom operating information and zooming inhibition information from an external device; and variator control means for controlling a zooming operation of said variator lens means according to the received second zoom operating information and the zooming inhibition information and the first zoom operating information, and an imaging apparatus having: imaging means for imaging an object and for outputting an image signal; camera-body-side information input means for receiving the first zoom operating information and zoom position information from said lens-side information output means; camera-body-side zoom operating means for receiving the second zoom operating information to be supplied to said variator lens means; camera-body-side information output means for outputting said lens-side information input means the second zoom operating information and the optical zooming inhibition which is used for inhibiting said variator lens means from performing a zooming operation; electronic zooming means for performing electronic enlargement processing on an image represented by the image signal; and electronic zooming control means for controlling said electronic zooming means according to the first zoom operating information, the zoom position information and the second zoom operating information, wherein a cycle of transmission and reception of information between said lens-side information output means and said camera-body-side information input means and between said lens-side information input means and said camera-body-side information output means is nearly equal to a cycle of a standard television vertical synchronization signal.
