IMAGE PICKUP MODULE MANUFACTURING METHOD, AND IMAGE PICKUP MODULE MANUFACTURING DEVICE

摘要

A manufacturing device holds a lens unit on a Z axis that is orthogonal to a chart surface of a measurement chart, holds an image pickup element unit on the Z axis, picks up an image of the measurement chart by an image pickup element while changing a Z-axis direction position of the image pickup element unit held on the Z axis in a state in which current is applied to a second lens drive unit and a third lens drive unit of the lens unit held on the Z axis, adjusts the position and a tilt of the image pickup element unit relative to the lens unit on the basis of image pickup signals that are obtained in the case where the image of the measurement chart is picked up, and fixes the image pickup element unit to the lens unit.

1. A method of manufacturing an image pickup module including a lens unit that includes a lens group and an image pickup element unit that is fixed to the lens unit and includes an image pickup element for picking up an image of a subject through the lens group,
wherein the lens unit includes a first lens drive unit that moves at least a part of lenses of the lens group in a first direction extending along an optical axis of the lens group and second and third lens drive units that move at least a part of lenses of the lens group in second and third directions, which are orthogonal to the optical axis of the lens group, respectively, the image pickup element unit includes an electrical connection portion that is electrically connected to the image pickup element, the method comprises: a first step of holding the lens unit on an axis orthogonal to a measurement chart so that the second and third directions are perpendicular to the direction of gravity, and holding the image pickup element unit on the axis; a second step of changing relative positions of the lens unit and the image pickup element unit, which are held on the axis, and the measurement chart in a direction of the axis, and driving the image pickup element through the electrical connection portion to pick up an image of the measurement chart at each relative position by the image pickup element; and a third step of adjusting at least the relative positions of the lens unit and the image pickup element unit in the direction of the axis on the basis of image pickup signals, which are obtained in the case where the image of the measurement chart is picked up by the image pickup element, and fixing the image pickup element unit to the lens unit.
