Patent ID: 7259792

Claim:
An optical system controller for a video camera, comprising: a lens barrel having therein a movable optical system including a zooming lens, a focusing lens, and an iris diaphragm; movable mechanisms for focusing control, zooming control, and aperture control, said movable mechanisms being arranged around the lens barrel; a control means that controls the driving of said movable mechanisms for focusing control, zooming control, and aperture control; a first, second, and third optical display means that are arranged near said movable mechanisms for focusing control, zooming control, and aperture control which are arranged around the lens barrel; a first, second, and third detecting means to detect respectively the position of said focusing lens, the position of said zooming lens, and the opening of said iris diaphragm which change in the lens barrel; a first display control means that causes said first optical display means to make a display in response to the position of the focusing lens which has been detected by said first detecting means; a second display control means that causes said second optical display means to make a display in response to the position of the zooming lens which has been detected by said second detecting means; and a third display control means that causes said third optical display means to make a display in response to the opening of the iris diaphragm which has been detected by said third detecting means, wherein the first optical display means is arranged along said focus adjusting movable mechanism, the second optical display means is arranged along said zoom adjusting mechanism, and the third optical display means is arranged along said aperture adjusting movable mechanism.
