Abstract

PURPOSE: To make it possible to perform the selection processing in arrangement patterns in a high speed, by using array data to select constituents of the compactly expressed array graphic form in the selection region.
CONSTITUTION: In case that the graphic data selecting circuit is utilized as the external circuit of the computer and so on, selection region data [(X1, Y1), (X2, Y2)] are stored from computer 1 to the selection region register in deciding circuit 3 by signal line 100. Next, array data (M, N, Δx, Δy) are stored in the array data register in array expanding circuit 2 similarly. After that, each time graphic data are sent by the signal line, respective array element positions are calculated and graphic data are converted to new graphic data and sent to deciding circuit 3 by signal line 101. In this case, array position data (I, J) indicating the current array position are sent to computer 1 by signal line 102. Deciding circuit 3 compares graphic data and contents of the selection region register with each other and interrupts computer 1 by signal line 103 for condition agreement to recognize the array position of current selection graphic data from array position data.
