ABSTRACT:
Methods and apparatus for creating a digital image in which exposure varies by region of the image are described. The image may be created from first and second images. In one embodiment, a method comprises writing pixels of the first image that are within a first region of a space to pixel locations in a memory that correspond with coordinates of the respective first image pixels. A replacement pixel is generated by combining a pixel of the first image that is within the first region with a spatially corresponding pixel of a second image. The replacement pixel is written to a pixel location in the memory that corresponds with the coordinates of the replacement pixel. Pixels of the first image that are within a second region of the space may be written to pixel locations in the memory that correspond with the coordinates of the respective first image pixels.
