Title:
CAMERA MODULE ADJUSTMENT METHOD, LENS POSITION CONTROL DEVICE, CONTROL DEVICE AND CONTROL METHOD FOR LINEAR MOTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/083356
Kind Code:
A1
Abstract:
The present invention pertains to a camera module adjustment method, a lens position control device, and a control device and control method for a linear motion device that enable optimization of any focus-subject distance using the state of a camera module in which an image pickup element and an actuator are combined. The present invention comprises: a position sensor (53) that detects the position of a lens (50) and outputs a detection position signal; a storage unit (541) that stores a position code value corresponding to a lens position serving as the focal length of the lens, and that is rewriteable; a target position signal generation unit (542) that outputs a target position signal on the basis of a position code value and a target position code value; and a control unit (543) that generates a control signal on the basis of the target position signal and the detection position signal.
