Abstract: Systems, methods, and non-transitory media are provided for reducing resource and power usage and requirements in staggered high dynamic range (HDR) applications. For example, a first exposure including a set of image data associated with a frame can be stored in memory. The first exposure has a first exposure time and is captured by an image sensor during a first time period associated with the frame. The first exposure can be obtained from the memory, and a second exposure including a set of image data associated with the frame can be obtained from a cache or the image sensor. The second exposure has a second exposure time and is captured by the image sensor during a second time period associated with the frame. The sets of image data from the first and second exposures can be merged, and an HDR image generated based on the sets of image data merged.
