1. A method comprising:
capturing, by an image sensor, a first plurality of images of a scene, wherein each image of the first plurality of images is captured with a different total exposure time (TET); based at least on the first plurality of images, determining a TET sequence for capturing images of the scene, wherein determining the TET sequence comprises determining that the scene is a high dynamic range (HDR) scene and defining a short TET value, a long TET value, and a fallback TET value; capturing, by the image sensor, a second plurality of images of the scene, wherein images in the second plurality of images are captured using the TET sequence; and based at least on the second plurality of images, constructing an output image of the scene, wherein constructing the output image of the scene comprises (a) attempting to align (i) one or more of the images in the second plurality of images captured with the short TET value, with (ii) one or more of the images in the second plurality of images captured with the long TET value, (b) determining that alignment of (i) the one or more of the images in the second plurality of images captured with the short TET value, and (ii) the one or more of the images in the second plurality of images captured with the long TET value has failed, and (c) in response to determining that the alignment has failed, aligning and combining one or more of the images in the second plurality of images captured with the fallback TET value to form the output image. |
