Charge coupled device/charge super sweep image system and method for making

DETAILED DESCRIPTION I claim: 1.
A method for processing an image for a charge coupled device (CCD) image system comprising: sensing said image on an array of photosites, each of said photosites accumulating charge in response to light transmitted by said image; selecting a row of said photosites for processing; transferring charge accumulated by said row of photosites representing a first line of signal into an associated series of charge transfer channels; using a resistive gate traveling wave technique for sweeping the first line of signal to a storage buffer adjacent said array within a single horizontal blanking interval of said image system; repeating said steps of sensing, selecting, transferring and sweeping for at least a second line of signal within said single horizontal blanking interval; and reading out said first and second lines of signal from said storage buffer as a multi-channel output signal from said image system.
2.
The method of claim 1 further including the step of applying a first charge clearing sweep of said charge transfer channels prior to selection of the row of photosites.
3.
The method of claim 1 further including the step of applying a charge clearing sweep of a selected portion of said storage buffer prior to sweeping said first or second line of signal into said storage buffer.
4.
The method of claim 1 further including directing excess charge in said charge transfer channels into clearing drains during said sweeping of said first or second line of signal into said storage buffer.
5.
A method for processing an image for a charge coupled device (CCD) image system comprising: sensing said image on an array of photosites, each of said photosites accumulating charge in response to light transmitted by said image; selecting a row of said photosites for processing; transferring charge accumulated by said row of photosites representing a line of signal into an associated series of charge transfer channels; using a resistive gate traveling wave technique for sweeping the line of signal to a storage buffer adjacent said array within a single horizontal blanking interval of said image system; repeating said steps of sensing, selecting, transferring and sweeping for all said lines of signal on said array; reading out said lines of signal in said storage buffer as a multi-channel output signal from said image system
