Abstract
An image capture device is used to identify object range information, and includes: providing an image capture device, an image sensor, a coded aperture, and a lens; and using the image capture device to capture a digital image of the scene from light passing through the lens and the coded aperture, the scene having a plurality of objects. The method further includes: dividing the digital image into a set of blocks; assigning a point spread function (psf) value to each of the blocks; combining contiguous blocks in accordance with their psf values; producing a set of blur parameters based upon the psf values of the combined blocks and the psf values of the remaining blocks; producing a set of deblurred images based upon the captured image and each of the blur parameters; and using the set of deblurred images to determine the range information for the objects in the scene.
