Blur correction apparatus

Apparatus comprising:

• a) a first member including a coil for generating magnetic flux;
• b) a second member including a hall element;
• c) a third member moveable relative to the first and second members, and including
• 1) an optical element,
• 2) a first magnet facing the coil, and
• 3) a second magnet arranged adjacent to the first magnet, such that the first magnet is arranged between the second magnet and the coil, and such that the second magnet is arranged between the first magnet and the hall element;
• and
• d) a blur correction controller adapted to
• 1) receive a first input indicative of blur due to shaking,
• 2) receive a second input indicative of magnetic flux detected by the hall element,
• 3) determine a blur correction value based on the first and second inputs received, and
• 4) provide an output, based on the determined blur correction value, to induce providing a controlled current through the coil,
• wherein, responsive to current flowing through the coil, the first and second magnets cause the third member to move relative to the first member in a direction perpendicular to an optical axis of the optical element.

Apparatus comprising:

• a) a first member including a two coils, each for generating magnetic flux;
• b) a second member including two hall elements;
• c) a third member moveable relative to the first and second members, and including
• 1) an optical element,
• 2) two first magnets, each facing a respective one of the two coils,
• 3) two second magnets, each arranged adjacent to a respective one of the two first magnets, such that each of the two first magnets is arranged between respective ones of the two second magnets and the two coils, and such that each of the two second magnets is arranged between respective ones of the two first magnets and the two hall elements;
• and
• d) a blur correction controller adapted to
• 1) receive a first input indicative of blur due to shaking,
• 2) receive a second input indicative of magnetic flux detected by a first one of the two hall elements,
• 3) receive a third input indicative of magnetic flux detected by a second one of the two hall elements,
• 3) determine two blur correction values based on the first, second and third inputs received,
• 4) provide a first output, based on a first one of the two determined blur correction values, to induce providing a first controlled current through a first one of the two coils, and
• 5) provide a second output, based on a second one of the two determined blur correction values, to induce providing a second controlled current through a second one of the two coils,
• wherein, responsive to the first and second controlled current flowing through the two coils, the two first magnets and the two second magnets cause the third member to move relative to the first member in a direction perpendicular to an optical axis of the optical element.
