Abstract: PURPOSE: A device and a method for controlling the operation of a camera module are provided to reduce current consumption required for autofocusing. CONSTITUTION: A device for controlling the operation of a camera module includes a lens module (400), a first stopper, a second stopper, and a control unit. The lens module moves along an optical axis. The first and second stoppers limit a maximum movement part of the lens module. The control unit sets the effective movement section by applying a first correction value to the maximum movement section so that the lens module is moved between points spaced at a predetermined interval from the first and second stoppers. If the minimum of distances between the first and second stoppers and the lens module is larger than a predetermined threshold value, the control unit sets the corrected effective movement section by applying a second correction value.

Abstract: A stepping motor is provided to transmit power even in a slimed volume by converting transmitted rotatory power into linear advance and retreat movement with a shift as a main driving axis to transmit the rotatory power, thereby being applied to small portable digital instruments and digital camera. A stepping motor comprises a rotation unit(130) and a yoke unit. The rotation unit includes a ring-shaped permanent magnet(133), a pipe-shaped coupling member, and a shift(131). The pipe-shaped coupling member is inserted into a center of the permanent magnet and has a screw thread on an inner circumferential surface. The shift advances and retreats along the screw thread by being screw-coupled to the screw thread of the coupling member. The yoke unit includes a ring-shaped bobbin(143), upper and lower yokes(141,142), and electromagnetic coils(141a,142b). The ring-shaped bobbin surrounds a lateral surface of the permanent magnet. The upper and lower yokes are coupled symmetrically up and down about the bobbin and have a plurality of teeth or tooth units(141b,142a) protruded toward the bobbin side. The electromagnetic coils surround circumferences of the teeth or tooth units.
