Method for manufacturing imaging module and imaging-module manufacturing device

A method for manufacturing an imaging module,

• wherein the imaging module comprises;
• a lens unit having a lens group and an imaging device unit being fixed to the lens unit and having an imaging device that captures an image of an object through the lens group, and
• wherein the lens unit comprises;
• a movable image-stabilizing unit having the lens group and a magnetic member and an elastic support unit supporting the movable image-stabilizing unit such that the movable image-stabilizing unit is movable in a direction perpendicular to an optical axis of the lens group and tiltable around an axis perpendicular to the optical axis,
• the method comprising:
• a first step of holding the lens unit and the imaging device unit on an axis perpendicular to a measurement chart;
• a second step of changing a relative position of the lens unit and the imaging device unit, held on the axis perpendicular to the measurement chart, and the measurement chart on the axis and capturing images of the measurement chart using the imaging device at the respective relative position;
• and
• a third step of calculating a compensation amount using image-capturing signals acquired as a result of the imaging device capturing the images of the measurement chart, adjusting a tilt of the imaging device unit relative to the lens unit, and fixing the imaging device unit to the lens unit,
• wherein in the second step, the images are captured in a state where a magnetic field having a magnitude equal to a magnitude of a magnetic field applied to the movable image-stabilizing unit, when the lens unit is installed in an electronic device including a magnetic-field generating unit, from the magnetic-field generating unit is applied to the movable image-stabilizing unit,
• the method further comprising:
• a step of measuring an intensity of the magnetic field applied to the movable image-stabilizing unit;
• and
• a step of determining whether or not a measurement result of the intensity of the magnetic field is equal to the magnitude of the magnetic field applied to the movable image-stabilizing unit, when the lens unit is installed in the electronic device including the magnetic-field generating unit, from the magnetic-field generating unit.
