IMAGE CAPTURING MODULE AND METHOD OF ALIGNING AND ASSEMBLING THE SAME

摘要

An image capturing module includes an image sensing unit and an actuator unit. The image sensing unit includes a circuit substrate and an image sensing chip disposed on the circuit substrate. The actuator unit includes a housing frame disposed on the circuit substrate and a movable lens assembly movably disposed inside the housing frame. The image sensing chip includes an image sensing area having a first geometric center line and a first geometric center point, and the movable lens assembly has a second geometric center line and a second geometric center point. Whereby, when the predetermined energy is provided for the actuator unit to shift the movable lens assembly, the second geometric center line (or the second geometric center point) of the movable lens assembly can be accurately aligned with the first geometric center line (or the first geometric center point) of the image sensing area.

主权项

1. A method of aligning and assembling an image capturing module, comprising:
providing an image sensing unit and an actuator unit, wherein the image sensing unit includes an image sensing chip, and the actuator unit includes a housing frame having a predetermined position point or a predetermined position line and a movable lens assembly movably disposed inside the housing frame; providing a predetermined energy for the actuator unit, wherein the center position of the movable lens assembly relative to the predetermined position point or the predetermined position line of the housing frame is shifted to a fixed offset location, for obtaining a predetermined horizontal direction and a predetermined horizontal distance from the predetermined position point or the predetermined position line of the housing frame to the center position of the movable lens assembly; removing the predetermined energy; horizontally shifting the predetermined position point or the predetermined position line of the housing frame relative to the center position of the image sensing chip along a predetermined horizontal offset direction and by a predetermined horizontal offset distance, wherein the predetermined horizontal direction is opposite to the predetermined horizontal offset direction, and the predetermined horizontal distance is the same as the predetermined horizontal offset distance; and fixing the actuator unit on the image sensing unit, when the predetermined position point or the predetermined position line of the housing frame relative to the center position of the image sensing chip has been horizontally shifted along the predetermined horizontal offset direction and by the predetermined horizontal offset distance.
