CALCULATING APPARATUS FOR IMAGE SIGNAL CORRELATION

摘要

In a correlation computing device including circuits for segmenting (1, 2, 3) a digital input signal into two kinds of digital signals according to a predetermined rule, arithmetically processing (4, 6) the two digital signals for each of the segments, and cumulatively adding (7) the results of signal processing for each of the segments, a high-order bit elimination circuit (9) is provided for eliminating high-order bits of the digital input signal prior to the signal processing.
