US Patent 10498971 Systems and methods for high-dynamic range imaging

Aspects of the present disclosure relate to systems and methods for generating High-Dynamic Range (HDR) images. An example device may include a camera, one or more processors, and a memory. The memory may include instructions that, when executed by the one or more processors, cause the device to determine, from a preview image captured with an initial exposure value by a camera, a first exposure value for capturing a reference image, and a second exposure value for capturing a first non-reference image, wherein the second exposure value is based on a difference between the initial exposure value and the first exposure value. Execution of the instructions may further cause the device to capture the reference image using the first exposure value, capture the first non-reference image using the second exposure value, and blend the reference image and the first non-reference image in generating an HDR image.
