Imaging systems and methods for generating motion-compensated high-dynamic-range images

A method of capturing images, comprising:

• capturing a first interleaved image having rows of long-exposure image pixel values that are interleaved with rows of short-exposure image pixel values;
• capturing a second interleaved image having rows of short-exposure image pixel values that are interleaved with rows of long-exposure image pixel values;
• detecting a motion region using the first interleaved image and the second interleaved image;
• selecting either the first interleaved image or the second interleaved image as a reference image;
• and
• generating a high-dynamic-range image by generating image pixel values in the motion region that are based exclusively on the long-exposure image pixel values and the short-exposure image pixel values from the interleaved image that was selected as the reference image.

A system, comprising:

• a central processing unit;
• memory;
• input-output circuitry;
• and
• an imaging device, wherein the imaging device comprises:
• an image sensor configured to capture first and second interleaved images each having rows of short-exposure image pixel values that are interleaved with rows of long-exposure image pixel values;
• and
• circuitry configured to detect a motion region using the first and second interleaved images, select either the first interleaved image or the second interleaved image as a reference image, and generate a high-dynamic-range image having image pixel values in the motion region that are based exclusively on the long-exposure image pixel values and the short-exposure image pixel values from the interleaved image that was selected as the reference image.
