Claim 4 specifies in pertinent part the following
limitations: "means for adjusting disparity while adjusting
focal length of the zoom lenses to avoid loss of stereo
effect." Similarly, claim 13 specifies in pertinent part the
following limitations: "adjusting disparity while adjusting
focal length of the zoom lenses to avoid loss of stereo
effect.” Accordingly, claims 4 and 13 require inter alia
linking the adjustment of disparity with the adjustment of the
focal length of zoom lenses of right and left cameras to avoid
loss of stereo effect.
The examiner fails to show a teaching or suggestion of
the limitations in the applied prior art. Robinson links the
adjustment of several parameters of a camera. In one
instance, “[p]arallel tracking of the zoom control, and focus
control of the two camera lenses 14, is achieved ....” Col.
