Abstract: Provided are systems and methods for determining timestamp information for High Dynamic Range and/or Wide Dynamic Range composite images. For example, an apparatus is provided that comprises an image sensor configured to capture a plurality of sub-frames of a scene, wherein each sub-frame comprises an image of the scene captured using an exposure time that is different from at least one other exposure time of at least one other sub-frame of the plurality of sub-frames. The apparatus is configured to receive, for each of the plurality of sub-frames, sub-pixel image data corresponding to a first portion of an image frame, determine composite image data corresponding to the first portion of the image frame based on values of the received sub-pixel image data for the plurality of sub-frames, identify an indicator based on the sub-frames corresponding to the received sub-pixel image data, and determine timestamp information, based on the identified indicator.

In one aspect, a method includes capturing multiple images of a scene using a digital imager. The method includes generating a blended image by combining the multiple images, and executing an object detection algorithm on the blended image to locate and identify objects. The method includes determining a region of the identified object that contains a light source, and generating bounding box data around the light source region. The method includes communicating the bounding box data to the digital imager and updating the exposure time of the sensors in the bounding box region.
