Abstract
This disclosure provides systems, methods, and devices for image signal processing that support improved detail keeping in photography through increased dynamic range and/or highlight-keeping. The image signal processing may be performed on data received from a split-pixel image sensor with two sets of sensor elements with different sensitivities. The image signal processing may include receiving image data comprising: first data from a first set of sensor elements and second data from a second set of sensor elements capturing a representation of the scene with a different sensitivity that the first set of sensor elements; determining an output dynamic range for an output image frame; and determining an output image frame based on at least one of the first data and the second data and based on the output dynamic range. Other aspects and features are also claimed and described.
