AUTOFOCUS METHOD OF CAMERA USING TEMPERATURE AND GRAVITY SENSORS, APPARATUS FOR CONTROLLING CAMERA, AND SYSTEM INCLUDING THE SAME |
摘要 |
A camera controller controls a camera module, which includes a plastic lens and an actuator controlling a position of the lens in an open-loop mode. The camera controller includes an offset determiner configured to determine a first offset corresponding to a measured temperature of a camera and a second offset corresponding to a measured posture of the camera, a lens moving range determiner configured to determine a moving range of the lens based on the first offset and the second offset, and an autofocus calculator configured to output a position control signal for controlling a position of the lens and seek a focus position of the lens based on the lens moving range. |
