[0037] specific implementation
[0038] In the following description, well-known functions or structures will not be described in detail to avoid unnecessary confusion with the content of the present invention.
[0039] The digital camera device and method with autofocus system disclosed by the present invention can be completed by the following devices and steps:
[0040]In the process of shooting the scene, the image to be taken is captured by the image sensor 1 at the beginning of the image, and the image is converted into electric charge by the A / D digital conversion circuit 8, and then enters the image processing unit 7, and is processed by the image The autofocus algorithm module AF 3 in the processing unit performs calculations and judges the sharpness of the image, and the microcontroller MCU 4 outputs a PWM pulse width modulation signal 5 according to the processing result of the image processing unit 7, thereby further generating a signal cont...
