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 an image sensor, at least two coded apertures, and a lens; storing in a memory a set of blur parameters derived from range calibration data for each coded aperture; capturing images of the scene having a plurality of objects using each of the coded apertures; providing a set of deblurred images using the captured images from each coded aperture and each of the blur parameters from the stored set; and using the set of deblurred images to determine the range information for the objects in the scene.
