DIGITAL TWO-DIMENSIONAL FILTER AND TWO-DIMENSIONAL FINITE IMPULSE RESPONSE (FIR) FILTER

摘要

PURPOSE: To provide new technique for an FIR two-dimensional filter capable of optimizing a vertical filter without exerting bad influence upon the realization of a related horizontal filter. ;CONSTITUTION: A scanning conversion circuit 10 to give vertical stripe scanning by output 11 is contained. The circuit is followed by two delay memories of p-line + p-data (here p=4). C, B, A are buses to carry the outputs of the conversion circuit 10, a first delay memory 12 and a second delay memory 14 respectively. These outputs C, B, A are sent to the vertical filter 16, and if necessary, to other analog vertical filter.;COPYRIGHT: (C)1993,JPO
