The key to the auto-focusing technique based on image processing is the selection of focus measure reflecting image definition. Usually the measures derived are on the premise of the images acquired with the same scene. As for the remote-sensing camera working in linear CCD push-broom imaging mode
the premise doesn't exist because the scenes shot are different at any moment
which brings about difficulties to the selection of the focus measure. To evaluate the image definition
the focus measure based on blur estimation for rough adjustment is proposed to estimate the focused position by only two different lens positions
which greatly saves the auto-focusing time. Another evaluation function based on edge sharpness is developed to find best imaging position in the narrow range. Simulations show that the combination of the two measures has the advantages of rapid reaction and high accuracy.
