Problems solved by technology
However, the disadvantage of the extended depth-of-field imaging module is that it cannot restore the close-up subject image into a clear image, so when the imaging module is close to the subject, the extended depth-of-field imaging module will cause the problem of image blur
[0005] Since the auto-focus imaging module and the extended depth-of-field imaging module have different device structures and imaging methods, it is difficult for the traditional imaging module to combine the advantages of both, and it still consumes a lot of energy or cannot take close-up shots. The problem

The invention provides an image capturing module, which includes a lens group, an image sensing component, an image processing unit, an actuator and a control unit. The image sensing component is arranged on the image side of the lens group for sensing the image formed by the lens group and outputting an image signal. The control unit drives one of the image processing unit and the actuator according to the definition of the image signal. The image processing unit is used for performing digital image processing on the image signal, so as to improve the definition of the image signal. The actuator is connected to the lens group to mechanically adjust the focus or position of the lens group to obtain a clear image. The invention also provides an imaging method.
Description
technical field [0001] The invention relates to an imaging module and an imaging method thereof. Background technique [0002] The current image capturing method is to project the image onto a charge coupled device (CCD) sensor or a complementary metal oxide semiconductor (complementary metal oxide semiconductor, CMOS) sensor. Due to the problem of the so-called depth of field in imaging, for the fixed-focus imaging module, only objects within a certain distance from the imaging can be clearly imaged. [0003] The autofocus (AF) technology enables the imaging module to automatically adjust the position of the focusing lens group of the imaging module according to the distance of the object, so that the image of the imaging module on the imaging plane is clear. Therefore, the auto-focus imaging module needs to have a certain actuating mechanical structure, and the position of the focusing lens group is continuously adjusted by the actuating mechanical structure to provide im...
