More Information
Summary:An automatic focus method includes: catching an image data in a focus area; calculating the image data to get a contrast value curve via a contrast value algorithm; obtaining a contrast weight of each contrast value; calculating an adapted contrast value by multiplying the contrast value to the contrast weight; and adapting the focus according to the adapted contrast value curve. An automatic focus system using the automatic focus method is further disclosed.
