摘要： Electronic devices may include image sensors. Image sensors may be used to capture images having rows of long-exposure image pixel values that are interleaved with rows of short-exposure image pixel values. The long-exposure and short-exposure values in each interleaved image frame may be interpolated to form interpolated values. A combined long-exposure image and a combined short-exposure image may be generated using the long-exposure and the short-exposure values from the interleaved image frames and the interpolated values from a selected one of the interleaved image frames. The combined long-exposure and short-exposure images may each include image pixel values from either of the interleaved image frames in a non-motion edge region and image pixel values based only on the image pixel values or the interpolated values from the selected one of the interleaved images in a motion or non-edge region. High-dynamic-range images may be generated using the combined long-exposure and short-exposure images.
