  • Adjusting method of camera module, lens position control device, control device of linear movement device, and controlling method of the same
    Patent number: 10674070
    Abstract: An adjusting method of a camera module, a lens position control device, a control device of a linear movement device, and a controlling method of the same are provided in a state of the cameral module in which an imaging element and an actuator are combined. The camera module includes a position sensor (53) that detects a position of a lens (50) to output a detection position signal, a storage unit (541) that stores and rewrites a position code value corresponding to the position of the lens, a target position signal generation unit (542) that outputs a target position signal based on the position code value and the target position code value, and a control unit (543) that generates a control signal based on the target position signal and the detection position signal.
