Βι¶ΉΤΌΕΔ

The number of picture sampling points required for automatic colour-camera registration

Report 1969-25

Published: 1 January 1969

Abstract

It has been proposed that an automatic colour-camera registration system should be developed for use within the Βι¶ΉΤΌΕΔ. The correction system will sample selected areas of picture information and, from these samples, will generate correction waveforms which will be applied to the camera in order to offset the registration errors.

The purpose of this investigation was to ascertain the bandwidths necessary for the correction signals, as these will determine the number of samples of picture information required. The results obtained indicate that the minimum number of samples required to reconstitute the correction waveforms would be thirty-five, in a rectangular array of seven samples horizontally by five samples vertically.
