Claim:
1. A method of operation of an image processing system comprising: providing an image processing device having a lens system; receiving a source image on the image processing device; detecting an edge of the source image; calculating an edge profile of the edge, the edge profile having an amplified glitch; calculating a gradient profile of the edge profile based on the amplified glitch; eliminating the amplified glitch by eliminating a gradient value, which is less than a gradient threshold, from the calculated gradient profile to create a smoothed gradient profile; calculating an edge width measure of the edge from the smoothed gradient profile; determining a parabolic curve from the calculated edge width measure; retrieving a depth from a least edge width measure which is a lowest point of the determined parabolic curve; and adjusting the lens system to the depth for capturing an image of an object.
