Abstract:
An apparatus and method for determining confidence in focus direction detection, including the steps of capturing a plurality of images, calculating sets of matching errors and blur difference estimations relating to the images, capturing a plurality of object images; calculating sets of matching errors and blur difference estimations relating to the images, calculating a confidence indicator as a function of either the matching errors or blur difference estimations, and automatically adjusting a focus control element in response to said confidence indicator exceeding a threshold value.
