Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention draws in advance a screen group composed of a group of figures and characters determined by a plurality of coordinates and a screen, and stores it in a display controller so that it can be stored in a host computer. The present invention relates to an automatic image conversion conversion input method for a graphic display device that displays a command screen according to the display command.

[0002]

2. Description of the Related Art Conventionally, when drawing a screen, a drawing design drawing describing display figures, coordinates, and necessary attributes is created.
This drawing design drawing is directly input to the drawing device, or is input by a digitizer based on the drawing design drawing. Also, a method of displaying the screen read by the scanner as it is is adopted.

[0003]

However, when inputting directly from the drawing design drawing to the drawing device or when inputting with the digitizer, the drawing device and the drawing design drawing are specified for each coordinate designation and for each drawing. In contrast, there is no choice but to strictly proceed with the drawing operation while confirming the correctness, the operator's burden is very large, and the drawing work must spend a lot of time, which is extremely inefficient. In addition, when displaying the screen read from the scanner as it is, the document to be read is required to have high quality with no inconvenient display and has a large memory capacity. ， It is not practical to display. The present invention has been made in view of the above-mentioned points, and an object of the present invention is to automatically recognize a drawing such as a drawing design drawing, a design drawing, or a photograph read from a scanner to identify a drawing order. The present invention aims to provide an automatic image conversion conversion input method for a display device which can approximate a rough sketch and can store and display a large number of screens.

[0004]

[Means for Solving the Problems] In other words, a means for achieving the object is to draw a fixed image portion in advance and display a display controller regardless of the presence or absence of a function of dynamically displaying data, graphs and the like online. This is stored in, and the screen is read online by a command from the host computer, and as a drawing input means for the display device, a draft drawing such as a drawing design drawing, design drawing and photograph is received from the scanner and read by the drawing device, In a drawing device that has display position correction and arbitrary enlargement / reduction functions, and creates a screen with graphic figures such as straight lines, broken lines, chain lines, triangles, quadrangles, circles, arcs and fans The number of colors that can be displayed is summarized and displayed,
Except for the specified erase-prohibited figure, by deleting the same color dot groups of a certain size or less, the display that is inconvenient for drawing is erased, and comments etc. are added to the draft and this is set in advance as the automatic conversion prohibited area. By means of this means, it is possible to clearly indicate the correction after the automatic drawing conversion processing.

Next, a means for recognizing a figure that can be drawn by the drawing device is provided by a figure search cursor that includes a line width capable of drawing a group of dots of the same color, and the figure type is sequentially overwritten from the figure. It is a method that makes it possible to perform approximate reproduction display of the underline by recognizing, drawing the reverse order of the recognized figure as the drawing order, downloading this to the display controller, and setting it as the drawing order. Note that the fourth aspect is that a known fuzzy theory that improves the accuracy of recognition of the figure type is applied.

[0006]

The present system is effective in that it has the following functions. (1) The reading screen can be enlarged or reduced. (2) The position of the screen can be moved. (3) It is possible to display the gradation of the color read by the scanner. (4) It is possible to set to erase a group of dots of the same color that are smaller than a certain size, but to prohibit the erase even if the size is a certain size. (5) A graphic that can be drawn by the drawing device can be recognized and drawn from the drawing graphic group. (6) It is possible to replace with the drawing format that the drawing device has. (7) If it is not overwritten by the figure drawn by item (5), it can be specified as a figure that can be drawn by the drawing apparatus. (8) According to the items (5) and (7), the order of drawing and drawing is determined so that the overwriting portion is post-processed. (9) Automatic conversion and setting of prohibited areas are possible in advance, and after the conversion processing, the display can be overwritten by the item (3).

[0007]

[Table 1]

Table 1 is an example of figures that can be drawn by the drawing apparatus. Among them, a multi-line figure is a figure formed by three or more single-line figures, and a quadrangle is two horizontal lines and two horizontal lines. A figure formed by a vertical line of a book and a figure formed by a single-line figure having two or more sides including an irregular quadrangle is classified as a polygon. Surface-based graphics are a general term for graphics with color filling, and are roughly classified into paint-based and paint-based graphics. The fill system is a method for filling a single figure formed by sides, arcs, or both of a multi-line figure other than a polygon, a circle, a fan, etc., and is drawn simultaneously with the figure by specifying attributes. The painting system is a painting on an irregular figure formed by a polygon, an edge, and an arc, and is drawn separately from the figure. An embodiment of the present invention will be described in detail below with reference to the drawings.

According to the drawing apparatus 12 as described above,
In the drawing, the drawing device that consists of the same drawing of the drawing design drawing, the design drawing, and the rough sketch of the photograph.
In addition to recognizing the figures that can be drawn on the display device and drawn on the display device, the figures that can be drawn are sequentially extracted if they are not overwritten by the figure, and are recognized as a set of irregular figures composed of edges and arcs. Approximately, the extraction order and the reverse order are set as the drawing order, the drawing command and the attribute unique to the display controller are converted and received by the display controller 14, and a predetermined screen is displayed by a command from the host computer 16.

According to a second aspect of the present invention, on a screen read by the scanner 11, a means for erasing dots having the same color and having a predetermined size or less such as dirt that is inconvenient for display, and erasing by the function. This is a method that allows you to specify a graphic that is prohibited.

Further, in claim 3, the automatic conversion prohibited area can be set prior to the automatic drawing conversion, and the conversion prohibited command portion and the automatic conversion impossible portion are converted on the screen where the automatic drawing conversion is performed. This is a method that can be displayed by means that can be distinguished from the completed part. Further, in claim 4, in the recognition of the figure, in order to increase the accuracy thereof, a method which is generally well known is applied to the fuzzy theory.

Next, these functions will be described. A draft such as a drawing design drawing or a design drawing read by the scanner 11 is input to the drawing device 12. The drawing device 12 has a display position correction function and an arbitrary enlargement / reduction function, and creates a screen with graphic figures such as a straight line, a broken line, a chain line, a triangle, a quadrangle, a circle, an arc, and a fan. The color data read from is composed of dots of the same color and is drawn.

Further, the drawing device 12 recognizes a figure which can be drawn on the display device, and if the figure does not overwrite the above-mentioned graphic figure drawn on the drawing device 12, the drawing device 12 The figures that can be drawn are sequentially extracted, further recognized and approximated as a set of indeterminate figures composed of edges and arcs, and the drawing order is defined as the extraction order and the reverse order, and the replacement drawing is performed to transmit this to the display controller 14. Drawing commands and attributes are converted. Then, the converted drawing command data is received by the display controller 14, and in response to a command from the host computer 16, causes the graphic display 15 to display the screen in which the above-described graphic figure is specified.
