摘要：An arrangement (100) for determining the position of the energy center (o') ofthe image (S') of a luminous object by barycentric calculation within a window (122)surrounding said image (S') and covering p.sub.l . times.p.sub.c elements of a charge-transfer matrix (120). According to the invention, the arrangement has:

a first mode of operation, during which on the one hand said matrix (120) is read bygrouping the N.sub.l lines m-by-m (m < p.sub.l) in the output register (121), whereas onthe other hand, the output register (121) is emptied by grouping, in the readarrangement (123) of the matrix (120), l (l < p. sub.c) consecutive elements from theoutput register (121), so as to determine the brightest zone m×l (124) of the matrixdefining the approximate position of the image (S') on the matrix,

a second mode of operation, during which the matrix (120) is first read, by groupingthe lines n-by-n (n > p.sub.l), thereafter, line by line in a zone (125) of k lines (k > p.sub.l)located around said brightest zone (124), and finally, by again grouping the lines n-by-nuntil all the N. sub.l lines have been used up.

Use: solar view finders.
