Abstract: The method includes in order to generate a composite image: identifying, in the frame of a video stream captured by a camera, a motion characteristic associated with moving objects in a scene while the camera captured a sliding window of the video stream. The method includes for a plurality of frames in the sliding window: controlling, by the processing circuitry, a weight of blending of the frame based on the identified motion characteristic to enable the composite image to be generated according to the controlled weights of blending of the plurality of frames in the sliding window.

Abstract: A method includes obtaining, using at least one processing device of an electronic device, multiple image frames having different exposure levels. The method also includes determining whether a moving saturated region is present in at least some of the image frames. The method further includes selecting one of the image frames as a reference frame, where the selected image frame depends on whether the moving saturated region is present in at least some of the image frames. The selected image frame may have a first exposure level when the moving saturated region is present in at least some of the image frames, and the selected image frame may have a second exposure level longer than the first exposure level when the moving saturated region is not present in the image frames.

Abstract: A method includes obtaining multiple image frames captured during a multi-frame capture operation. The method also includes determining that two or more of the multiple image frames are available for selection as a reference frame, where the two or more image frames are associated with at least two different exposure levels. The method further includes determining whether a moving saturated region is present in the two or more image frames. The method also includes, in response to determining that the moving saturated region is present, selecting an image frame from among the two or more image frames having a first exposure level. In addition, the method includes, in response to determining that the moving saturated region is not present, selecting an image frame from among the two or more image frames having a second exposure level, where the second exposure level is longer than the first exposure level.

Abstract: A method includes obtaining, using at least one processor of an electronic device, a high dynamic range (HDR) input Bayer image. The method also includes generating, using the at least one processor of the electronic device, a plurality of synthesized images at different exposure levels based on the input Bayer image. The method further includes fusing, using the at least one processor of the electronic device, the synthesized images to generate a fused image. The method also includes generating, using the at least one processor of the electronic device, a gain map based on the fused image. In addition, the method includes applying, using the at least one processor of the electronic device, a gain based on the gain map to the input Bayer image.
