Abstract
PURPOSE:To provide an easy and immediate display of even a result that has not been processed completely by filtering pictures at a high speed. CONSTITUTION:The picture processing system is provided with a plural number of picture memory FM1 - FM3, memory address control circuit MAC, arithmetic circuit ALU, read badk circuit RBC, etc. When the original picture is stored from the external memory M into FM1 through host computor HCPU, interface circuit INF and common bus, it is read out by the address signal from MAC, each specified picture element number subjected to scanning and reading is integrated in ALU, the result of integration is transfered by RBC to another picture memory (for example, FM2), the scanning-reading direction of this picture memory is set to the direction at right angles to the first scanning-reading direction and, then, the integration of each specified picture element number is made in ALU again. Therefore, smoothing or filtering such as the secondary differential calculus, etc. can be executed at a high speed by comparing certain picture elements with boundary picture elements.
