Abstract
Disclosed are CCD imagers, each with a composite image register comprising two component image registers with interleaved charge transfer channels is operated with charge transfer in opposite directions from the two image registers. Also disclosed are apparatuses for suppressing transfer smear from the output video signals supplied from such CCD imagers.
Claims2
A CCD imager having:
- first and second charge-coupled-device image registers each comprising a respective plurality of charge transfer channels and having their respective charge transfer channels spatially interleaved to receive a radiant energy image, each of said charge transfer channels having a respective output connection;
- means for recurrently transferring charge packets in parallel through the charge transfer channels of said first image register in a first direction to the respective output connections of its charge transfer channels;
- means for recurrently transferring charge packets in parallel through the charge transfer channels of said second image register in a second direction opposite the first direction to the respective output connections of its charge transfer channels;
- and
- means responding to the charge packets transferred from the output connections of the charge transfer channels in said first image register and in said second image register for generating a video output signal.
