Claim 0:
1. An imaging device for triggering an automatic pullback, the imaging device comprising:
one or more processors that operate to:
collect image data from an object, target, or sample, and obtain or identify a reference frame for a region of interest (ROI) in the image data;
determine an amount of a change in an image intensity of each of one or more other frames of the image data showing the region of interest (ROI) relative to an image intensity of the region of interest (ROI) shown or as in the reference frame;
determine whether the amount of, or a level in, the change for each of the one or more other frames of the image data showing the region of interest (ROI) indicates that a partial clearing or a diagnostic clearing of the object, target, or sample is or has been achieved where a clearance metric is above a threshold; and
issue a signal based on the determined amount of, or the determined level in, the change indicating that the partial clearing or the diagnostic clearing of the object, target, or sample is or has been achieved and based on the clearance metric being above the threshold, the signal operating to trigger the automatic pullback.
