Abstract:
1. A method for generating a high dynamic range (HDR) image from a set of multiple input images, each input image being assigned a bracket index, comprising: (a) dividing each input image into a set of tiles, wherein all images are divided into the same set of tiles; (b) determining a reference bracket index for each tile of the set of tiles, comprising: (c) based on the set of reference bracket indices for the tiles, detecting ghost-inducing pixels in the set of input image on a tile-by-tile basis by comparing, for each tile, each input image whose bracket index is not the reference bracket index with the input image whose bracket index is the reference bracket index, and generating a ghost map for each input image which indicates ghost-inducing pixels in that image; and (d) generating a HDR image using the set of input images and the corresponding ghost maps.
