Abstract

PURPOSE:To accurately correct an original drawing in a short period by adding a corrected image onto an original drawing output image with a color having a hue different from the original drawing image to turn the output image into a code and controlling the coded corrected image data and the original drawing with correspondence secured between them. CONSTITUTION:A control means 17 gives the command control to a drawing storage means 11, an image output means 12, a corrected image output means 13, a corrected image adding means 14, a drawing reading means 15, and a graphic memory means 16. A corrected color image having a different hue from an original drawing is added onto the output original drawing image after a coded drawing is outputted. Therefore the original drawing image can be clearly identified from the corrected image and the drawing data on the corrected image can be easily coded in a short time. Thus it is possible to store and control both the original drawing and the corrected image data and also to prepare, store and control the different types of corrected image data against the same original drawing.
