Abstract:
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), wherein histograms are stored in a training database and are based on at least two captured images of respective scenes, and wherein the stored histograms are associated with respective target pixel values; determining a TET sequence for capturing images of the scene, wherein determining the TET sequence comprises determining a scene histogram based on at least one of the images in the first plurality of images of the scene, comparing the scene histogram to at least one stored histogram, determining one or more target pixel values for the scene based on the respective target pixel values, and selecting one or more TET values to use in the TET sequence based on the one or more determined target pixel values; 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.
