Abstract
Method of using an image capture device to identify range information for objects in a scene includes providing an image capture device at least one image sensor, a coded aperture, a first optical path including the coded aperture and a second optical path not including the coded aperture; storing in a memory a set of blur parameters derived from range calibration data for the coded aperture; capturing a first and second image of the scene, corresponding to the first and second optical paths, the second image having equal or higher resolution than the first; providing a set of deblurred images using the first capture image and each of the blur parameters from the stored set; using the set of deblurred images to determine the range information for the objects captured by the first optical path; and using the range information to control the image capture or processing of second image.
