Abrégé
(EN)

The present invention proposes a camera module and a method for driving the same, the camera module including an image pick-up unit including a lens to photograph an object, a lens transfer unit configured to move the lens of the image pick-up unit, a focusing driving unit configured to operate the lens transfer unit, and an ISP (Image Signal Processor) configured to select, as an auto-focused image, an image of the object by dividing an image area of the object photographed by the image pick-up unit to a plurality of sections, controlling the focusing driving unit to allow each section to be auto-focused and photographed, detecting and comparing a focusing level of same pixel from each image of the object photographed from each auto-focused section.
