Latest Patents

Among his latest patents, Park has developed a "Camera module and method for auto focus thereof." This invention relates to an apparatus designed to control the auto focus of a camera module that utilizes a voice coil motor actuator. The camera module includes a sensing unit that detects the movement of the lens unit. A controller manages the lens movement based on signals from the sensing unit. The technology features an initial operation command that prompts the lens to move to an endpoint in its movement range, ensuring precise positioning for focus adjustments. Upon receiving a focus operation command, the controller skillfully aids in the lens movement to achieve a desired focus position by compensating for any errors detected during operation.

Additionally, another patent titled "Apparatus and method for controlling auto focus of camera module" further explores the mechanics of autofocus technology. This invention allows the controller to generate signals comprising first and second frequency signals directed to a moving coil. It processes variable current or voltage from these signals to calculate focus position values, adjusting accordingly while minimizing noise from the Optical Image Stabilization (OIS) system.
