1. A method, comprising:
detecting blooming in a depth map at least in part from pixel brightness information;
identifying a depth range affected by the blooming;
invalidating pixels that are both at the depth range and within or adjacent to the blooming; and,
generating another depth map that includes invalidated depths for the invalidated pixels but retains depths for other pixels at the depth range that are not adjacent to the blooming.
