INTEGRATED CIRCUIT FOR PROCESSING PICTURE

摘要

PURPOSE: To minimize the number of the connection lines to peripheral circuits of a circuit for a data processing by sliding a window of a prescribed dimension by one row each and simultaneously performing the processing arithmetic operation of source pictures for local pictures stipulated by the window. CONSTITUTION: A picture memory 11 receives picture data through a bus 10. A control processor 13 generates an address for reading the memory 11 and an integrated processing circuit 14 reads data from the memory 11, performs the processing arithmetic operation of the pictures and outputs the result to the bus 15. The picture memory is the matrix of I×J pieces of picture elements dij. A processor 14 uses the four windows W1 -W4 of (5 rows × 5 column) shifted by one row each, successively takes out the local pictures and performs a picture processing. When the windows W1 W4 reach the respective final rows, the windows W1 -W4 are moved in a group and the same processing is repeated.
