Abstract

PURPOSE:To improve the operability of a drawing producer by performing the operations to be carried out on a digitizer on a display means and therefore displaying the picture information obtained by supplying the original drawing information to the same display part without imparing the original drawing. CONSTITUTION:The picture information supplied through a drawing reading part 1 is stored temporarily in a picture memory part 2a. A processing part 2 reads the picture information out of the part 2a and sends it to a display part 3 after the entire original drawing is stored. The part 3 displays the picture information on its screen. Based on the drawing displayed on the part 3, an operating part 4 is actuated to shift an index to a desired coordinate position. Then a coordinate point is supplied with operation of a push-button, etc. provided at the part 4. A processing part 5 codes the indicated coordinate point and graphic information and stores them in a code memory part 2b. At the same time, the part 5 converts the code information into the picture information and displays it to the part 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a drawing creation device using a computer.

[Conventional technology]

Traditionally, computer-based drawing creation devices (generally,
When creating drawings based on existing drawings or handwritten drawings, a device called a digitizer is used in a CAD device. The drawing is fixed on the digitizer, and the digitizer is equipped with a coordinate specifying device for moving over the fixed drawing. When creating drawings,
Fix the above-mentioned existing or handwritten drawing that serves as the original drawing on the digitizer, move the digitizer's coordinate specifying device to the desired location on the drawing, and enter the information on the drawing into the computer by pressing a switch or other operations. do.

Drawings are created in this way, but in the input method using the digitizer, operations are performed on the original drawing, which often causes damage such as dirt to the original drawing. Moreover, it is difficult to tell which parts have been entered and which parts have not been entered, making it easy for input to be omitted, and furthermore, there are many cases where detailed parts on drawings cannot be entered or are entered incorrectly.

[Problem that the invention seeks to solve]

The present invention is intended to solve these problems of damage to original drawings and poor operability.

[Means and effects for solving the problems] This invention has the following features:
For this reason, the original drawing is read and input as image information, and the read drawing information is displayed on the display means, so that operations on a conventional digitizer can be performed on the display means. .

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

The figure shows the configuration of an apparatus according to an embodiment of the present invention, which includes a drawing reading section +11 that converts image information on a drawing into an electrical signal, a storage section (2), and an image stored in the storage section (2). A display unit (3) for displaying images that reproduces and displays signals, and an operation unit (3) for specifying coordinate points and graphic information on the display unit (3).
4), and is equipped with a processing section (5) that performs various data processing such as data storage, reading, and conversion, as will be described later.

The drawing reading unit (1) consists of a drawing reading device that reads the original drawing, reads the entire drawing so that it can be input as image information, and reproduces the drawing based on the read drawing information. The image signal of is stored in the storage section (2
) is recorded electrically. That is, by optically scanning the manuscript drawing, two-dimensional image information is converted into a serial electrical signal and sent to the processing section (5), which converts the serial data into a fixed bit length. (for example, 8 or 16 bits) and sends it to the storage unit (2). The storage unit (2) consists of an image storage unit (2a) and a code storage unit (2b) that stores coordinates and graphic information instructed by the operation unit (4), which are converted by the processing unit (5) as described above. The parallel data is temporarily stored in the image storage section (Za) for storing image information input by the drawing reading section (1). After storing the entire manuscript drawing, the processing unit (2) reads out the image information stored in the image storage unit (2a) and sends it to the display unit (3), where the image information is displayed on its screen. Display.

Further, the processing unit (5) sends data to the display unit (3) for displaying an index indicating the position coordinates on the display unit (3) by the operation unit (4). is now displayed.

The operation unit (4) is equipped with operation means such as push buttons,
Based on the drawing displayed on the display section (3) above, the operation section (4)
is operated to move the index all the way to the desired coordinate position, and then the coordinate point is input using the push buttons on the operating section (4).

The display unit 13) consists of a graphic display device such as a CRT, and the above-mentioned operating means for specifying graphic information on the display unit (3) include a light pen, a tablet notebook,
Pointing devices such as a mouse can be used. - Also, it goes without saying that the image on the display section (3) can be enlarged or reduced as necessary, improving operability and accuracy. The processing unit (5) encodes the coordinate points and graphic information specified by the above method and stores it in the code storage unit (2b), and also converts the code information sequentially input by the above method into image information. and displayed on the display section (3). In this way, the existing drawing is read by the drawing reading section fi+, and code information (vector information) is input on the display section (3) based on the image information (raster information). The base drawing information and the input image information are displayed on the same display section (3), and in that case, the display section (3) displays the original image and the image information based on the code by changing the display color or display brightness. By doing something like this, the two can be distinguished and displayed.

In this way, according to the above-mentioned embodiment device, instead of operating on the original drawing as in the conventional case, the entire drawing is inputted as image information by the drawing reading section (1), and the read drawing information is displayed on the display section ( 3), and operations on a conventional digitizer can be performed on this display section (3), so there is no need to worry about staining the original drawing, and when creating drawings based on existing drawings, etc., the original drawing can be used. can be prevented from causing damage. ±- Since the base one-page information and the input image information are displayed on the same display section (3), the operability is much better, and since they are displayed in different colors, it is easier to use than before. It is also possible to prevent input errors from occurring because it is difficult to distinguish between inputted and uninputted areas.

〔Effect of the invention〕

As described above, the present invention does not require any operations on the original drawing, so it does not damage the original drawing, and the drawing information that is the basis of the original drawing and the input image information can be displayed on the same display, so it is easy to operate. is significantly better. In addition, by displaying both the original drawing information and the input image information on the same display unit, it is possible to easily distinguish between the two by changing their display colors and display brightness, and If the information is displayed as , it is possible to reliably prevent input errors.
