Abstract: Multiple regions of a scene are identified, for example through user inputs to a touchscreen while the touchscreen displays preview frames of the scene. Multiple exposure settings are determined based on the identified regions. Each exposure setting is determined based on one of the identified regions, for instance to optimally expose that region. Multiple image frames are captured of the scene, with each image frame captured at a different one of the determined exposure settings. A high dynamic range (HDR) image of the scene is generated by merging the multiple image frames of the scene.
