With the simple lens of the eye, this sort of chromatic aberration results in images of different color being focused slightly differently. Pure fields of any given color can be brought into proper focus, through the adaptive action of the lens, but if objects of very different colors are seen in close proximity, a problem arises. The problem is at its worst, of course, with colors at the extremes of the visual spectrum – blue and red. If bright examples of both colors are seen together, the eye cannot focus correctly on both; the blue image focuses “behind” the red, as seen in Figure 2-9.
It takes time for this information to be conveyed to the brain and to be processed. We can reasonably expect, then, that there will be a maximum rate at which such changes can be perceived at all, but that this rate will vary with certain conditions, such as the brightness or contrast of the changing area relative to the background, the size of the object within the visual field, and so forth. We also should understand that the eye/brain system has evolved to track moving objects – to follow them and fixate upon them, even while they are moving – and how this occurs.
This is done in order to raise the flicker component to twice the frame rate, and thus minimize the perception of flicker by the audience. TEMPORAL RESPONSE AND SEEING MOTION 29 Figure 2-11 To show standard motion pictures (shot at 24 frames/s) on US standard television (approx. 60 fields/s), a technique known as “3:2 pulldown” is used. However, the uneven duration of the original frames, as seen now by the viewer, can result in certain objectionable motion artifacts. Figure 2-12 Effect of mismatched refresh and update rates.
