System and method to capture depth data of an image

摘要

Systems and methods of generating depth data using edge detection are disclosed. In a particular embodiment, first image data is received corresponding to a scene recorded by an image capture device at a first focus position at a first distance. Second image data is received corresponding to a second focus position at a second distance that is greater than the first distance. Edge detection generates first edge data corresponding to at least a first portion of the first image data and generates second edge data corresponding to at least a second portion of the second image data. The edge detection detects presence or absence of an edge at each location of the first portion and the second portion to identify each detected edge as a hard or soft edge. Depth data is generated based on the edge data generated for the first and second focus positions.
