Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
147 words
A camera which includes: a housing; a transparent closure at one end of said housing; an image pick-up tube within said housing; a lens within said housing positioned with its field of view extending through said transparent closure, adapted to form an image on said pick-up tube; means for rotating said lens about a scan axis so that its field of view will sweep from side to side, the plane in which said lens rotates passing through the axis of said housing; an optical joint rotatable about said scan axis to transmit said image from said lens toward said image pick-up tube; image rotating means adapted to rotate said image on said pick-up tube and in a plane perpendicular to the plane of rotation of said lens; and motor means operable to rotate said lens about said scan axis and simultaneously to rotate said image rotating means.
Claim 2
Dependent Claim
147 words
A camera which includes: a housing; a transparent closure at one end of said housing; an image pick-up tube within said housing; a lens within said housing positioned with its field of view extending through said transparent closure, adapted to form an image on said pick-up tube; means for rotating said lens about a scan axis so that its field of view will sweep from side to side, the plane in which said lens rotates passing through the axis of said housing; an optical joint rotatable about said scan axis to transmit said image from said lens toward said image pick-up tube; image rotating means adapted to rotate said image on said pick-up tube and in a plane perpendicular to the plane of rotation of said lens; and motor means operable to rotate said lens about said scan axis and simultaneously to rotate said image rotating means.
Claim 3
Dependent Claim
21 words
A camera as described in claim 1, in which said image rotating means includes means for rotating said image pick-up tube.
Claim 4
Dependent Claim
28 words
A camera as described in claim 1, in which said image rotating means includes prism means in the optical path between said lens and said image pick-up tube.
Claim 5
Dependent Claim
22 words
A camera as described in claim 1, in which said lens has a back focal length greater than its nominal focal length.
Claim 6
Dependent Claim
30 words
A camera as described in claim 1, in which said lens has a portion of its elements before said optical joint and the remainder of its elements after said joint.
Claim 7
Dependent Claim
36 words
A camera as described in claim 1, in which said motor means drives a rotatable member that, in turn, drives said image rotating means, and said image rotating means drives said image for rotating said lens.
Claim 8
Dependent Claim
35 words
A camera as described in claim 6, in which said image rotating means includes means for rotating said image pick-up tube, and said lens has a back focal length greater than its nominal focal length.
