Abstract
A mechanism is described for facilitating hybrid tone mapping in camera systems according to one embodiment. A method of embodiments, as described herein, includes detecting a scene having a sequence of frames, and fusing the sequence of frames into a fused raw frame. The method may further include reconstructing the scene by performing global tone mapping and local tone mapping on the fused raw frame, and outputting an image reflecting the reconstructed scene based on the tone-mapped raw frame.
