Abstract
Abstract Apparatus for compensating for forward image motion in panoramic cameras by rotating the image about the optic axis of the camera. In an aircraft camera a first scanning mirror is rotated relative to a second scanning mirror about their common axis in order to provide compensation for the forward motion of the plane.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
100 words
In a panoramic camera including a first reflective member for scanning an area of interest and a second reflective member for receiving radiation from the first reflective member and projecting an image on the film of the camera the improvement in which one of said reflective members is offset by a predetermined fixed angle relative to the other about their common optic axis for rotating the image at the film about the optic axis a predetermined amount relative to the path of the image across the film to produce a component of image motion to compensate for forward image motion.
Claim 2
Dependent Claim
100 words
In a panoramic camera including a first reflective member for scanning an area of interest and a second reflective member for receiving radiation from the first reflective member and projecting an image on the film of the camera the improvement in which one of said reflective members is offset by a predetermined fixed angle relative to the other about their common optic axis for rotating the image at the film about the optic axis a predetermined amount relative to the path of the image across the film to produce a component of image motion to compensate for forward image motion.
Claim 3
Dependent Claim
12 words
The camera of claim 1 in which said reflective members are mirrors.
Claim 4
Dependent Claim
102 words
In a panoramic camera including lens means rotatable about its nodal point for scanning an area of interest and projecting an image of that area onto the film of the camera the improvement comprising deflection means disposed in the optic axis of said lens means and rotated about the optic axis a predetermined amount relative to the path of the image across the film for rotating the image at the film about the optic axis by a predetermined angle relative to the path of the image across the film to produce a component of image motion to compensate for forward image motion.
Claim 5
Dependent Claim
102 words
In a panoramic camera including lens means rotatable about its nodal point for scanning an area of interest and projecting an image of that area onto the film of the camera the improvement comprising deflection means disposed in the optic axis of said lens means and rotated about the optic axis a predetermined amount relative to the path of the image across the film for rotating the image at the film about the optic axis by a predetermined angle relative to the path of the image across the film to produce a component of image motion to compensate for forward image motion.
Claim 6
Dependent Claim
14 words
The camera of claim 3 in which said deflection member is a Dove prism.
Claim 7
Dependent Claim
99 words
In a panoramic camera including optical scanning means for scanning an area of interest and projecting an image of said area onto a film in the camera the improvement comprising optical means disposed on the optic axis of said optical scanning means rotated and a predetermined amount about the optic axis relative to the path of the image across the film for rotating the image at the film about the optic axis by a predetermined angle relative to the path of the image across the film to produce a component of image motion to compensate for foreward image motion.
Claim 8
Dependent Claim
99 words
In a panoramic camera including optical scanning means for scanning an area of interest and projecting an image of said area onto a film in the camera the improvement comprising optical means disposed on the optic axis of said optical scanning means rotated and a predetermined amount about the optic axis relative to the path of the image across the film for rotating the image at the film about the optic axis by a predetermined angle relative to the path of the image across the film to produce a component of image motion to compensate for foreward image motion.
