Abstract: A method and apparatus are disclosed for restoring an image captured through an extended depth-of-field lens. Preprocessed data relating to image degradation is stored and used during an image restoration process.

Abstract: Systems and methods are provided for performing optical simulations using parallel computations. In some embodiments, the optical simulations can be performed on a computer system using raw image data provided by a camera. The computer system may include a central processing unit (CPU) and a graphics processing unit (GPU), where the GPU may be configured for the parallel computations. The CPU can build a lookup table of lens characterization data, such as point spread function (PSF) data. Using the lookup table, the GPU can perform the optical simulations. For example, the GPU can compute a plurality of convolutions in parallel, each using PSF data and a window of pixels. The result of each convolution may produce a pixel value that approximates the effect of the lens on that pixel.
