Abstract
Various embodiments provide improved image resolution using a High Dynamic Range (HDR) image sensor. A computing device calculates long exposure settings and short exposure settings for image sensors of a computing device. The long exposure settings and the short exposure settings are applied to a first image sensor of the image sensors, and only the short exposure settings are applied to a second image sensor of the image sensors. Some embodiments use an interleaved High Dynamic Range (iHDR) image sensor as the first image sensor, and a Clear or Mono image sensor for the second image sensor. Various embodiments generate a synchronized image that includes a first image generated by the first image sensor and a second image generated by the second image sensor. Upon receiving the synchronized image, some embodiments fuse the first image and the second image to improve the image resolution of the first image capture.
