Abstract
Embodiments are directed towards enabling digital cameras to digitally process a captured a Low Dynamic Range image sequence at a real time video rate, and to convert the image sequence into an High Dynamic Range (HDR) image sequence using a pipelined architecture. Two or more image frames are captured using different exposure settings and then combined to form a single HDR output frame in a video sequence. The pipelined architecture operate on adjacent image frames by performing an image alignment, an image mixing, and a tone mapping on the adjacent image frames to generate the HDR image sequence.
