A FOV(field of view) dependent LOS(line of sight) scan method and
apparatus for a turret aided camera system with continuous zoom optics is
disclosed. According to this invention, the scan width and rate of the
LOS are automatically determined as a function of the FOV selected by the
user: scan width=f1(FOV, m) and scan rate=f2(FOV, te) where m is the
observation range constant and te is the eye integration time. Moreover,
the sensitivity to the FOV can be controlled by adjusting the relevant
parameter sets (said m and te), allowing the user to select the scan
condition proper to himself. This invention is quite useful for all kinds
of turret aided camera system (the IR or day light TV cameras) for
reconnoitering application.
