<p>PURPOSE: To provide a data processing method capable of quickly and precisely predicting the movement of a moving image. CONSTITUTION: High speed Fourier transformation is applied to a reference block R and a target block array T to find out Y (α,β) and Z (α,β), a multiplier 11 finds out a product of Y (α,β) and Z (α,β) and the inverted Fourier transformation (IFFT) of the product is executed to find out a 1st calculation result 12. Similarly high speed Fourier transformation is applied to a reference block R1 and a target block array T1 to find out YY (α,β) and H (α,β), a multiplier 13 finds out a product of YY(α,β) and H (α,β) and the IFFT of the product is executed to find out a 2nd calculation result 14. A difference between twice the 1st calculation result 12 and the 2nd calculation result 14 is found out by a subtracter 15 and a square error e (k, l) is calculated. The position of the most coincident block (K, L) can be detected by searching the minimum value of the e (k, l).</p> |
