Claim 7:
8. The method of claim 1, wherein continuously monitoring the display component of the display device for display of the first particular image comprises:
capturing video images of the first particular image in a first sequence of video frames in an image plane of the video camera; and
for each respective video frame of at least a first subset of the first sequence of video frames, computationally comparing the video image of the first particular image captured in the respective video frame with a first template image,
and wherein detecting that the first particular image ceases being displayed after having been detected in the display component during the monitoring comprises:
detecting at least one failed computational comparison for which the captured image of the first particular image fails to match the first template image to within a first matching threshold, wherein the at least one failed computational comparison follows one or more consecutive affirming computational comparisons for each of which the captured image of the first particular image matches the first template image to within the first matching threshold.
