The image drawing synthesis processing device 7 for creating the corrected image drawing data.

[Functions of Each Part] The input device 4 inputs a line, a circle, a circular arc, a comment, a region deletion, etc. as a correction instruction C1 for starting and stopping the device and correcting a drawing.

In the image drawing file 1, a drawing read by a scanner or the like is stored as raster image drawing data, and when the drawing is corrected, the corrected drawing is stored as raster image drawing data. To be done. This can be taken out as a drawing on paper by a hard copy or the like.

The display conversion device 2 is a device for converting the image drawing data stored in the image drawing file 1 into display data in a format that can be displayed on the display device 3.

The display device 3 displays the display data from the display conversion device 2, and displays the corrected display data when the drawing is corrected.

The input data analysis device 5 analyzes the correction instruction data of the drawing input from the input device 4 and adds additional vector data D2 for adding lines, circles, arcs, comments and the like to the drawing, and area deletion instruction data D1. The correction instruction data C2 including and is created.

The data conversion device 6 is a device for combining additional vector data to be added to the drawing for correction of the drawing with the image drawing data which is the original drawing and converting it to image drawing data for making a corrected drawing.

The image / drawing combination processing device 7 is an area deletion instruction for deleting additional vector data such as lines, circles, arcs, and comments added to the drawing output from the data conversion device 6 and an instructed area of the original drawing. The data and the image drawing data which is the original drawing stored in the image drawing file 1 are combined to create the corrected image drawing data, which is stored in the image drawing file 7.

[Operation] Next, referring to FIGS. 1 and 2, the operation of correcting the drawing will be described.

The image drawing data which is the original drawing stored in the image drawing file 1 is used as the original drawing F1 in the display conversion device 2
Is converted into display data and displayed on the display device 3.
The correction position is designated while looking at the displayed drawing.

First, in order to delete the circle of the original drawing F1, two center lines of the circle, and a part of the dimension line, the position to be deleted from the input device 4 is designated as an area. The correction instruction C1 is analyzed by the input data analysis device 5 and processed into the area deletion instruction data D1. Since this area deletion instruction data D1 is data of coordinate values, it is converted into raster data by the data conversion device 6 in order to be combined with the image drawing data.
This raster data is bit data in which only the area to be deleted is turned off, and the corrected drawing F2 is created by ANDing the bit data as a combination with the original drawing F1 read from the image drawing file 1 by the image drawing combination processing device 7. Then, the image drawing file 1 is updated. This is displayed on the display device 3 via the display conversion device 2. This procedure first deletes and corrects part of the original drawing.

Next, when adding a circle and two center lines of the circle and the dimension line to the corrected drawing F2, the positions of the circle, the line and the dimension line are designated from the input device 4. The correction instruction C1 is analyzed by the input data analysis device 5 and processed into additional vector data D2. This additional vector data D2 is
