Abstract

PURPOSE:To cover the specified region with uniform color by a simple instruction from the computer, by changing the vector data into the data representing in closed region on the line where the vector data is first and finally read out with the video generator. CONSTITUTION:The data of the picture to be displayed is generated with the computer 1 and it is written in each address of the refresh memory 2. Further, the command register 6 approximates the peripheral of one closed region to be represented with the same digital data with the set of the straight line part, the position data of the end point for the straight line part, it is read out with the vector generator 7 and written in the memory 2 with the graphic pattern generator 8. In this case, in the circuit 8, the vector data is changed into the data representing the closed region on the line where the vector data is first and finally read out, and on the intermediate line, the data present between the vector data are changed into the data representing the closed region. Thus, the specified region can be colored uniformly with a simple instruction from the computer 1.
