Patent ID: 8786959

Claim:
An AF camera module comprising: an lens module for capturing an image of an object; an image sensor aligned with the lens module for sensing the image captured by the lens module; a color separation unit electrically connected to the image sensor and configured for separating the image sensed by the image sensor into red image, green image and blue image; a main processor unit electrically connected to the color separation unit, the main processor unit being configured for calculating MTF values of the image and determining a shooting mode of the AF camera, wherein the shooting mode comprises a close shooting mode and a long shooting mode; an image processing unit electrically connected to the main processor unit, the image processing unit processing the image according to the MTF values calculated by the main processor unit to compensate blurs of the image caused by out of focus when the long shooting mode is selected; and a driving unit electrically connected to the main processer unit, the driving unit moving the lens module to an optimum focusing position according to the MTF values calculated by the main processor unit when the close shooting mode is selected.
