IPC: G02B7/28
Filed: 1995-04-12
Abstract: PURPOSE: To attain zooming operation without causing blurring by driving a focusing lens on the basis of information on the in-focus position of the focusing lens with respect to the position of a variable power lens which is divided by a divisor within the movable range of the variable power lens. CONSTITUTION: A microcomputer (AF microcomputer) 116 for controlling AF detects the current position Zn of the variable power lens 102 by counting the number of step driving pulses supplied to a zooming motor 119. What position X on a locus table stored in the microcomputer 116 the variable power lens 102 exists at is calculated by X=Zn/ΔV...a. ΔV is the quotient when the number of step pulses equivalent to the movable range of the lens 102 is divided by the division number of the divisor. When the remainder (a) is not found, the data on the position of the focusing lens 105 equivalent to the position of an address X is read out of the locus table in the microcomputer 116. When the remainder (a) is found, an interior division point is read out. By setting the point as the in-focus position, the focusing lens 105 is driven.
