Abstract
A method of using an image capture device to identify range information for objects in a scene, includes providing an image capture device having at least one image sensor, a lens and a coded aperture, storing in a memory a set of blur kernels derived from range calibration data for the coded aperture, capturing a first and second image of the scene having a plurality of objects, corresponding to first and second optical magnifications, respectively. The method further includes providing a set of deblurred images using the capture images from each magnification and each of the blur kernels from the stored set, and using the set of deblurred images to determine the range information for the objects in the scene.
