1. An imaging device for camera and light source synchronization, the imaging device comprising:

  • an image processing module to detect a current location of an object in a captured image generated by the imaging device;

    a location prediction module to predict a next location of the object in a next captured image, generated by the imaging device, based on (i) the current location of the object and (ii) historical data that identifies previously detected locations of the object in corresponding previously captured images generated by the imaging device; and

    an illumination module to (i) determine an illumination interval defining a period of time during which a light source of the imaging device is to illuminate a set of sensor lines of the imaging device during the capture of the next captured image based on the predicted next location of the object, wherein the set of sensor lines corresponds with the predicted next location of the object and (ii) activate the light source of the imaging device to illuminate only the set of sensor lines of the imaging device that was determined to correspond to the predicted next location of the object throughout the determined illumination interval, wherein to active the light source comprises to sequentially expose each sensor line of the set of sensor lines of the imaging device to capture the next captured image.
