This is a kind of focusing controlling module used in image photography, which can drive a walking motor or a piezoelectricity material and control the focus distance between at least a lens and a image photography subassembly. This module comprises a image figuring unit, a displacement controlling unit, a walking motor driving unit and a piezoelectricity material driving unit. Thereinto the image figuring unit can receive the image signals incepted by the image photography subassembly, and calculate the best resolving ratio value. The displacement controlling unit can determine the best focusing distance between the lens and the image photography subassembly according to the best resolving ratio value, to output a displacement controlling signal to the walking motor driving unit or the piezoelectricity material driving unit, so as to control the focusing distance between the lens and the image photography subassembly and achieve the purpose of compatible use in the walking motor or the piezoelectricity material. Besides it can get rid of the trouble of changing the controlling module in the producing process.
Description
technical field [0001] The present invention relates to a focus control module for image capture, in particular to a focus control module used on an image capture device. . Background technique [0002] With the advent of the digital age, coupled with the vigorous development of related software and hardware technologies, various digital devices have begun to gain people's recognition and are widely used in daily life. For example, in digital image processing, it used to be It belongs to the work of professionals, but now with the popularization of digital cameras (DC), digital video cameras (DV), digital image scanners and other products, coupled with the advancement of computer equipment and image software functions, anyone can become a professional. Professional image processing personnel. [0003] The imaging quality of a general digital image capture device (such as a digital camera) is not only related to image capture components, such as a charge coupled device (CCD...
