4.6.2.9 Issue: Iris Mismatch (Depth of Field/Exposure)
Iris mismatch occurs when images in an image pair present different
maximum and minimum focal near and far focal planes (Figure 4.9) . This
typically takes the form of an area of interest coming into or leaving sharp
focus at different times in L and R during a zoom or camera move. This
mismatch may vary over the course of the shot because of variations in
the L and R image paths. In some cases, this mismatch is due to a simple
mis-synchronization of L and R. Mismatches in iris also impact color and
more specii cally, exposure.
4.6.2.10 Solution: Correct or Duplicate
Reduce or increase blur or focus of L relative to R or vice versa to simulate
the correct iris setting. Depending on the amount of the manipulation you
need to do, you might get additional artifacts from altered image in relation
to the unaltered image.
