Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
82 words
A device for suppression of inhomogeneous responses in the series of elements of a charge coupled imaging device comprising: a first series of drain means for storing said responses of each said elements to a uniform blurred image; a second series of drain means for storing said responses of said elements to said image in focus; means for comparing said stored responses of said first series of drain means with said responses of said second series of drain means to eliminate inhomogeneity.
Claim 2
Independent Claim
82 words
A device for suppression of inhomogeneous responses in the series of elements of a charge coupled imaging device comprising: a first series of drain means for storing said responses of each said elements to a uniform blurred image; a second series of drain means for storing said responses of said elements to said image in focus; means for comparing said stored responses of said first series of drain means with said responses of said second series of drain means to eliminate inhomogeneity.
Claim 3
Dependent Claim
14 words
The device of claim 1 wherein said means for comparing said responses comprises capacitors.
Claim 4
Dependent Claim
13 words
The device of claim 1 wherein said means for comparing comprises a register.
