Claim Text:
1. A camera module, the camera module comprising: an image sensor photographing an image of an object; an image signal processor processing the image of the object photographed by the image sensor and outputting the processed image; a display displaying the image of the object processed by the image signal processor; a touch detector detecting whether a particular region of the image of the object displayed on the display is touched by a user; a memory stored with an auto focus calibration code of the particular region, wherein the memory includes a look-up table sequentially recorded with addresses allocated with codes relative to infinity auto focus calibration and macro auto focus calibration; and an auto focus driver performing an auto focus on the image of the object touched on the display using the auto focus calibration code of the particular region stored on the look-up table in the memory, wherein each of auto focus calibration codes corresponds to each of a plurality of particular regions divided from the image of the object displayed on the display and is recorded as the address on the look-up table in the memory, wherein the auto focus driver receives a coordinate of the particular region detected by the touch detector, reading out from the memory the auto focus calibration code corresponding to the particular region of the image of the object touched on the display, and driving an auto focus actuator to perform an auto focus scan to the particular region of the image of the object touched by the user on the display.
