1. A method comprising:
determining a set of exposure settings;
providing, in first and second sequential timing windows to a sensor, respective first and second exposure settings from the set of exposure settings;
capturing, by the sensor, a sequence of images from a local area, the capturing such that the sensor first outputs a plurality of stale frames where no images are captured in the first and second sequential timing windows followed by a set of image frames where images are captured in third and fourth sequential timing windows at the respective first and second exposure settings, wherein each image frame is captured at a different exposure setting of the set of exposure settings; and
generating a (high-dynamic range) HDR image using the captured sequence of images.
