Method and system for detecting and capturing focused image

Abstract

The embodiments herein provide a system and method for detecting and capturing a focused image. The system comprises of an image capturing unit, edge detection unit and a focusing unit. The image capturing unit obtains plurality of images sequentially. The edge detection unit identifies region of interest in each of the obtained images and calculates edge strength value for the identified regions. The edge detection unit determines peak edge value from the edge strength values. The edge strength value quantifies degree of focus in the identified region. If the identified region is more focused, the number of edges is relatively more when compared with out-of-focus region. The peak edge value indicates that the identified region is well focused. The focusing unit causes the image capturing unit to capture focused image when the edge strength value reaches a predefined value of the peak edge value.
