Abstract
Apparatuses, computer readable media, and methods are disclosed for providing composite images and/or videos having a high dynamic range. The apparatus includes a video capture module for capturing video images of a scene at a differing exposure levels. The apparatus further includes a region identification module for identifying regions in the captured video images of the scene that may benefit from being individually optimally-exposed. The apparatus further includes a region adjustment module for updating the positions of the various identified regions within the scene and a region exposure adjustment module for determining optimal exposure settings for the various identified regions of the scene. A video subsystem composites and encodes the various optimally-exposed regions of the scene onto a video image of a static portion of the scene having a high dynamic range that was, e.g., captured at a different moment in time than the various optimally-exposed regions of the scene.
