Abstract
An auto-focusing camera module includes a lens module, an image sensor, a color separation unit, a controller, and a shape memory alloy. The lens module captures light signal of an object. The image sensor senses the light and forms an image. The color separation unit separates the image into red image, green image and blue image. The controller calculates MTF values of the image and determines a shooting distance between the lens module and the object. When the shooting distance is greater than a predetermined distance value, the controller processes the image according to the MTF values to compensate blurs of the image caused by out of focus; when the shooting distance is equal to or less than the predetermined distance value, the controller controls the shape memory alloy drive the lens module to an optimum focusing position for focus according to the MTF values.
