摘要： An imaging device includes: an imaging element; a lens disposed on a path of incident light to the imaging element; an actuator configured to displace the lens in a plane perpendicular to an optical axis; a position detecting element configured to generate a position detection signal indicating a displacement of the lens; and an actuator driver configured to feedback-control the actuator based on the position detection signal and a target code indicating a target displacement of the lens. The actuator driver includes: a correction circuit that converts a first detection code corresponding to the position detection signal into a second detection code having a linear relationship with an actual displacement of the lens; and a control circuit that controls the actuator so that the second detection code approaches the target code.

A low-impedance wiring is formed occupying a predetermined region. A first wiring pattern includes multiple copper wiring members arranged in parallel with predetermined intervals in a first copper wiring layer, each of which has a rectangular shape extending in a first direction. A second wiring pattern includes multiple copper wiring members arranged in parallel with predetermined intervals in a second copper wiring layer adjacent to the first copper wiring layer, each of which has a rectangular shape extending in a second direction orthogonal to the first direction. The region occupied by the first wiring pattern and that occupied by the second wiring pattern are arranged such that they at least overlap. The first wiring pattern and the second wiring pattern are electrically connected so as to have the same electric potential.

摘要： An actuator positions a movable portion including a lens in a first direction (Z-axis direction). An acceleration sensor generates first acceleration information ACC that indicates the acceleration applied to the image capture apparatus in the first direction. An actuator driver IC superimposes a correction value that corresponds to the first acceleration information on a base instruction value that corresponds to the target position to be set for the lens in the first direction. The actuator driver IC controls the actuator according to a corrected instruction value thus obtained.

摘要： A first detector compares an electric signal to be monitored with a first threshold. A second detector compares the electric signal with a second threshold. A first memory stores setting data of the first threshold. A second memory stores setting data of the second threshold. An interface circuit receives data from an external processor, and writes the data thus received to the first memory and the second memory. The protection circuit is configured such that data writing to the first memory is possible only when a predetermined condition is satisfied.

摘要： A position detection unit generates a position detection value PFB that indicates the position of a control target. A temperature detection unit generates a temperature detection value that indicates the temperature. A correction unit corrects the position detection value PFB. A controller generates a control instruction value SREF such that the position detection value PFB_CMP subjected to the correction matches a position instruction value PREF that indicates the target position of the control target. A driver unit applies a driving signal that corresponds to the control instruction value SREF to an actuator. The correction unit corrects the position detection value PFB such that the relation between the position detection value PFB and the actual position exhibits linearity that is uniform independent of the temperature.
