Abstract
A system for generating high dynamic range (HDR) imagery obtains a history frame associated with a first timepoint and with a first set of image capture parameters. The system obtains an image frame associated with a particular set of image capture parameters and captured at a second timepoint that is subsequent to the first timepoint, and the particular set of image capture parameters comprises the first set of image capture parameters or a second set of image capture parameters. The system generates a normalized image frame by applying a normalization operation to the image frame. The normalization operation may be determined based upon the particular set of image capture parameters. The system generates a weight map based upon at least the normalized image frame and generate an HDR image frame based upon the normalized image frame, the history frame, and the weight map.
