<p>PURPOSE:To obtain the correlation value of the (k-p)th stage by using the K stages of FET (first Fourier transformer) connected into a pipeline form and making use of the operation result obtained by the FET of the (k-p)th stage. CONSTITUTION:The picture data (f) having the 2<k> length N and the reference data (g) are stored in a buffer 2 after the operation of the 1st stage carried out by butterfly operation devices 1 and 1. Hereafter the FETs are successively executed in the same way via the buffers 21, 22-. The outputs of (k-p) stages are supplied to a multiplier 3 to perform a correlative operation. The result of this operation is supplied again to a pipeline FET device, and an operation adverse to that mentioned above is carried out over (k-p) stages. Then the final result (h) is obtained. Thus a correlative operation is possible with no increment of operation quantity.</p> |
