1. An electronic device comprising:

  • a first imaging camera;

    a second imaging camera;

    a modulated light projector to project at least a modulated light pattern;

    an ambient light sensor to detect an ambient light condition of the electronic device;

    a depth sensor including the modulated light projector and at least one of the first imaging camera and the second imaging camera;

    a controller to control at least one of a frequency, an intensity, and a duration of projections of the modulated light pattern by the modulated light projector responsive to the ambient light condition;

    wherein the electronic device is to determine depth data for detected spatial features using stereoscopic analysis of image data from the first imaging camera and image data from the second imaging camera responsive to the ambient light condition being greater than a threshold; and

    wherein the electronic device is to determine depth data for detected spatial features using reflections of the modulated light pattern captured by one of the first imaging camera or the second imaging camera responsive to the ambient light condition being less than the threshold.
