Patent ID: 7710491

Claim:
An optical equipment for forming an object image on a predetermined plane via an optical system including a focus lens and a zoom lens that move along an optical axis, comprising: a first storage unit that stores control information which represents a first relationship between a position of the focus lens and a position of the zoom lens for keeping an object of a predetermined distance in-focus; a second storage unit that stores correction data for correcting the control information stored in said first storage unit, the correction data representing a difference between the first relationship and a second relationship between a position of the focus lens and a position of the zoom lens for keeping the object of the predetermined distance in-focus, the first relationship being a relationship provided before production and the second relationship being a relationship provided after production; and a control unit that controls the focus lens and the zoom lens on the basis of the control information in said first storage unit and the correction data in said second storage unit, the control unit reading out the correction data stored in said second storage unit after the position of the focus lens is detected.
