Abstract: The present disclosure relates to methods and devices for high dynamic range (HDR) processing. In one aspect, the device may generate multiple frames, each frame being generated through a line-based exposure at a camera image sensor. The multiple frames can have at least two different exposure times and have staggered line-based exposure times during the at least two different exposure times. Additionally, the device can obtain movement information associated with the camera image sensor from a gyroscope sensor. The device can also modify the multiple frames based on the obtained movement information from the gyroscope sensor. Moreover, the device can combine the multiple frames into a staggered HDR image. The device can also generate a de-warp mesh for each frame based on the obtained movement information from the gyroscope sensor, and each frame can be modified based on its corresponding generated de-warp mesh.
