The ideal focus evaluation function should have the following characteristics: (1) it should be unbiased and have maximum value only when object plane and focal plane overlap; (2) it should have a single-peak: that is, focus evaluation function in the whole range has only one extreme value; (3) it should have high signal-to-noise ratio; in certain noise interference, autofocusing system can accurately detect defocused signal; (4) the computation burden should be as minimum as possible; this is a prerequisite for quick automatic focusing; (5) it should have high sensitivity; that is, autofocusing system should distinguish between focus and defocus; this is an important requirement for focusing precisely [4].
