Abstract
Systems, methods, and computer-readable mediums for autofocusing cameras in a videophone are disclosed. A videophone system may include a camera having a lens, a lens actuator configured to move the lens, and an image sensor configured to capture images received through the lens. The videophone system may also include a distance sensor configured to determine an object of focus distance between the camera lens and the object of focus. The system includes memory for storing instructions that when executed by a processor cause the camera lens to automatically focus on the object of focus. The processor includes a lookup table configured to correlate an object of focus distance determined by the distance sensor with a digital number that can be converted by a digital to analog converter to a power value sufficient to power lens actuator to move the lens to a predetermined focus position. The lookup table is configured to correlate an object of focus distance returned by the distance sensor with a digital number representing a lens position, such that the object of focus falls within a depth of field about a focal plane corresponding to the lens position.
