even- and odd-parity frames where the frames contain fixed
points of the image arranged in lines and represented by
digital values obtained by converting analog values output by
the detector, comprising the steps of:
aiming the camera at a scene;
destructuring the image of the scene, for a given lapse
of time, by making inconsistent changes to the camera settings
including modifying the focus of the camera and modifying a
direction of the camera line of sight;
acquiring, during the given lapse of time when the image
of the scene is destructed, m, where m is a positive integer,
frames with a same parity to calculate a mean frame in which
each point within the mean frame has approximately the mean
value of the digital values of corresponding points in the m
frame;
memorizing a correction frame in which the value of each
point corresponds to the value of corresponding points in the
mean frame to within a given constant value;
adjusting the camera settings to correctly observe the
scene; and
subtracting, for each point in the correctly observed
scene, the memorized value of the corresponding point from the
correction frame.
The Examiner relies on the following reference:
