Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
90 words
An endoscope for internally producing an image of a field of view, said image occupying an area larger than a cross-sectional area of said endoscope, the endoscope comprising: longitudinal walls; an image distorter for distorting light received from said field of view into a compact shape;; and an image sensor arranged in said compact shape to receive said distorted light to form an image thereon, wherein said image sensor is arranged along said longitudinal walls, the endoscope further comprising a light diverter for diverting said light towards said image sensor.
Claim 2
Dependent Claim
90 words
An endoscope for internally producing an image of a field of view, said image occupying an area larger than a cross-sectional area of said endoscope, the endoscope comprising: longitudinal walls; an image distorter for distorting light received from said field of view into a compact shape;; and an image sensor arranged in said compact shape to receive said distorted light to form an image thereon, wherein said image sensor is arranged along said longitudinal walls, the endoscope further comprising a light diverter for diverting said light towards said image sensor.
Claim 3
Dependent Claim
48 words
An endoscope according to claim 1 , wherein said image sensor comprises two parts, said distorter comprises an image splitter for splitting said image into two parts, and said light diverter is arranged to send light of each image part to a respective part of said image sensor.
Claim 4
Dependent Claim
26 words
An endoscope according to claim 2 , wherein said sensor parts are aligned on facing lengths of internal sides of said longitudinal walls of said endoscope.
Claim 5
Dependent Claim
27 words
An endoscope according to claim 2 , wherein said sensor parts are aligned successively longitudinally along an internal side of one of said walls of said endoscope.
Claim 6
Dependent Claim
28 words
An endoscope according to claim 1 , said image distorter comprising an astigmatic lens shaped to distort a square image into a rectangular shape of substantially equivalent area.
Claim 7
Dependent Claim
29 words
An endoscope according to claim 1 , further comprising a contrast equalizer for compensating for high contrasts differences due to differential distances of objects in said field of view.
Claim 8
Dependent Claim
19 words
An endoscope according to claim 1 , said image sensor comprising a plurality of pixels responsive to white light.
Claim 9
Dependent Claim
21 words
An endoscope according to claim 1 , said image sensor comprising a plurality of pixels responsive to different wavelengths of light.
Claim 10
Dependent Claim
23 words
