摘要: The accuracy of servo control of a corrective lens in an image stabilization control circuit is prevented from decreasing due to non-linear characteristics of a position-detecting element. A signal representing a component of vibration of an image pickup apparatus is generated based on an angular velocity signal from a vibration-detecting element. A microcomputer corrects the vibration component signal according to a predetermined correction function and generates a target position signal representing a target position of the lens. A position-detection signal based on an output from the position-detecting element is compared with the target position signal, and the position of the lens is servo-controlled. The correction function is set so that the characteristics of variation of the target position signal relative to the target position will be the same as the characteristics of variation of the position-detection signal relative to the actual position of the lens.

摘要: An electromagnetic induction device having a flat configuration that requires a relatively small space for installation on a circuit substrate includes a flat bobbin (1T) having a length (D1) smaller than a radial size (D2) thereof has primary and secondary windings (11, 12) wound thereon. This bobbin (1T) has coaxially aligned throughholes (20, 22) defined therein into which core legs (24T and 24T) of generally T-shaped first and second core pieces (23T, 23T) are inserted from opposite directions, respectively. Respective core arms (25T, 25T) of the first and second core pieces (23T, 23T) extend parallel to each other.
