Abstract
A method for extending the dynamic range of a depth map by deriving depth information from a synthesized image of a plurality of images captured at different light intensity levels and/or captured over different sensor integration times is described. In some embodiments, an initial image of an environment is captured while the environment is illuminated with light of a first light intensity. One or more subsequent images are subsequently captured while the environment is illuminated with light of one or more different light intensities. The one or more different light intensities may be dynamically configured based on a degree of pixel saturation associated with previously captured images. The initial image and the one or more subsequent images may be synthesized into a synthesized image by applying high dynamic range imaging techniques.
