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.
