Abstract: An auto-focus device includes a distance sensor, an actuator, a digital auto-focusing unit, and a controller. The distance sensor is configured for measure an object distance from an object to a lens module. The actuator is configured for drive the lens module to focus on an image sensor. The digital auto-focus unit is configured to process a blur image captured by the image sensor without focusing the lens module on the image sensor to get a sharp image. The controller is configured to activate the actuator when the object distance is shorter than a preset distance or otherwise activate the digital auto-focus unit.

Abstract: An image stabilizer control device includes a biaxial gyroscope, a processing unit and an actuator unit. The biaxial gyroscope senses movement of an imaging module and detects a first angular velocity of the imaging module in two reference planes perpendicular to each other. The processing unit generates a first driving signal in response to the first angular velocity. The actuator unit moves the imaging module to compensate the movement in response to the first driving signal. The biaxial gyroscope detects a second angular velocity of the imaging module in the two reference planes upon completing movement compensation associated with the first driving signal. The processing unit converts the second angular velocity into a second angle, compares the second angle with a predetermined angle range and generates a second driving signal in response to the comparison result. The actuator unit moves the imaging module in response to the second driving signal.
