Claim One:
1. A method for detecting and capturing a focused image, said method comprising: obtaining a plurality of images of a subject sequentially by changing focus and identifying a region of interest in each of the obtained images; calculating an edge strength value for each of the identified regions; determining a change in the edge strength value of the identified regions in consecutive images; determining a peak edge value from the edge strength values of the identified regions; upon determining the peak edge value, obtaining a plurality of the images and identifying the region of interest until the edge strength value of one of the identified region reaches a predefined threshold value; changing the focus and a obtaining plurality of the images; and capturing an image when the edge strength value of the identified region in one of the obtained images reaches a predefined value of the peak edge value, wherein the predefined value is 90% value of the peak edge value.
