Claim 15:
16. The system of claim 15, wherein continuously monitoring the display component of the display device for display of the second particular image comprises:
capturing video images of the second particular image in a second sequence of video frames in the image plane of the video camera; and
for each respective video frame of at least a second subset of the second sequence of video frames, computationally comparing the video image of the second particular image captured in the respective video frame with the second template image,
and wherein the operations further include:
detecting at least one failed further computational comparison for which the captured image of the second particular image fails to match the second template image to within the second matching threshold, wherein the at least one failed further computational comparison follows one or more further consecutive affirming computational comparisons for each of which the captured image of the second particular image matches the second template image to within the second matching threshold; and
recording information indicative of at least the second particular image and a further second timestamp marking a further second time at which the second particular image ceased being displayed in the display component.
