摘要: In an autofocus system, a focus measurement unit receives an image, and accordingly generates an associated focus value. A focus transform unit receives and then transforms the focus value provided by the focus measurement unit, therefore generating an associated transformed focus value. An in-focus position estimation unit obtains an in-focus position, in an analytical manner, according to some transformed focus values and some associated lens positions.
