Abstract
This disclosure provides systems, methods, and devices for image signal processing. In a first aspect, a method of image processing includes controlling an image sensor to capture image data for determining a standard dynamic range (SDR) representation of a scene, the image data comprising a first series of image frames captured with a first exposure level and a second series of image frames captured at a second exposure level. The SDR representation of the scene may be generated by determining a first output image frame based on at least a first image frame of the first series of image frames. Determining of an exposure level for the image sensor during the SDR image capture may be based on a second image frame of the second series of image frames captured by the image sensor in a multi-frame sensor configuration. Other aspects and features are also claimed and described.
