GPU-BASED LENS BLUR RENDERING USING DEPTH MAPS

Abstract:

Embodiments are disclosed for adding lens blur effects to input images. In particular, in one or more embodiments, the disclosed systems and methods comprise receiving a request to apply a lens blur effect to an image an accumulation region of the input image corresponding to a first pixel of an output image, determining a weight for each of the one or more source pixels based at least in part on an iris map for the one or more source pixels and a depth distance value between each of the one or more source pixels and the focal plane, and generating an output pixel value for the first pixel by calculating a weighted sum of the one or more source pixels from the accumulation region.
