Abstract

In a correlation system, such as may be used in an autolock follow arrangement, the correlation is effected on the basis of line integrals of data relating to pictures of substantially the same scene obtained at different times. The formation of line integrals allows a straightforward, linear processing technique to be used for the correlation.
