Description

DETAILED DESCRIPTION OF THE INVENTION <Technical Field> The present invention relates to a document creation and editing device.

<Prior art and its problems> Currently, document creation and editing devices (such as word processors) using microcomputers are in widespread use.

When operating this, the manuscript to be cleaned or referenced and the screen that displays the processing output are separated, so you have to move your eyes, face, or body to check both while proceeding. It is easy to introduce fatigue in specific parts of the body or fatigue in specific parts of the body.

In actual work, we try to bring the manuscript closer to the display screen, but sometimes the black text on the paper and the white, green, or orange colors on the display screen are different.
Eye strain is inevitable.

On the other hand, recently, it has been proposed to enrich the displayed information in measuring instruments by displaying the electrical signal waveform and the accompanying information in the form of letters and numbers on the same screen. , the purpose is to add information, and is not intended to actively assist human operations.

<Object of the Invention> The present invention provides a document creation/editing device that simultaneously displays an image of a document and a processed output to facilitate document creation/editing operations.

<Embodiment> The document creation and editing device of the present invention includes means for displaying an image of a document captured by an image processing device on a screen, and a means for displaying the image of the document and the processed display output on the same screen by superimposing the image of the document and the processed display output. It consists of a combination of means for processing the overlapping portions of these images, and means for appropriately processing the overlapping portions of these images.

An embodiment of the present invention will be described in more detail below with reference to the drawings.

FIG. 1 is a system block diagram.

The image of the document A optically read by the image processing device 1 is sent to the video information memory unit 2 as a serial signal of minute point images by the internal contrast enhancement circuit and digital signal conversion circuit. It will be done. At this time, timing control of scanning for imaging and storage in the video memory of the video information memory section 2 is performed by the display scan control section 3.

FIG. 2 shows details of the imaging processing device 1. The image capture processing device 1 includes an image capture device 1 that optically captures an image of a document A.
It consists of a digital signal converting circuit including a, an amplifier 1b, a comparator amplifier 1c, a buffer 1c', etc.

The alignment, enlargement, and reduction of the original are performed mechanically and optically. In addition, an imaging signal synchronized with the scanning signal from the display scanning control section 3 is extracted from the imager 1a, and a stable threshold value (threshold value can be adjusted by the resistor 1c'') is set using the broadband amplifier 1b. The output signal is amplified by a comparator amplifier 1c, which converts it into a digitized signal of 1 and 0. This digitized signal is sent to the video information memory section 2 as it is.

The video data stored in the video information memory section 2 is updated at any time until the image of the document A is fixed, but once it is fixed, it is held as is until one screen of work is completed. The accumulated video data is displayed on the display 5 via the video signal switching control section 4. This original image is displayed in one-to-one correspondence with a portion or the entire original unless processing as described below is performed.

After completing the settings for the original, you can begin work such as document creation, but before that, if necessary, you can make local corrections to the original image, such as removing unnecessary images due to dust or dirt on the original, or You can add supplements and repairs to the missing parts. This repair function is provided in the control processing device 6, which is composed of a microcomputer, etc., but it is easy to provide the control processing device 6 with functions such as adding and deleting lines and surfaces in addition to point repair.

After the original image is set on the screen, the operator uses the console 7, such as a keyboard, to create sentences on the screen by performing predetermined operations, but character patterns cannot be generated or deleted according to the input. , is performed by the above-mentioned control processing device 6, as is conventionally known. The generated designation data such as characters is stored in the display data memory section 8. Based on this data, a character in the character generation circuit section 9 is selected and outputted to the video signal switching control section 4 as a display output.

Specified data such as characters input from the console 7 is stored in the display data memory section 8, but if necessary, it is stored in an auxiliary memory such as a printer 10 or a magnetic disk as character output from the character generation circuit section 9. It can be output to the device 11. Note that the video information stored in the video information memory section 2 can be transferred to the printer 10 as described above, if necessary.
It is also possible to output to the auxiliary storage device 11.

I will now explain each of the main parts in a little more detail.

The video information memory section 2 is as shown in FIG. 3, and consists of a video signal bypass path 2a, a serial/parallel conversion section 2b, a parallel/serial conversion section 2c, a memory section 2d, and a memory scanning control section 2e.

When aligning the original, etc.,
Since the document image changes moment by moment, if we adopt a processing procedure that stores it one by one in memory and then displays it on the screen, there will be time constraints and it will be necessary to use ultra-high-speed circuit elements, making it impractical. Not on target. Therefore, the video signal from the image processing device 1 is directly bypassed to the display unit 5 through the bypass path 2a.
Make it possible to observe the original image. However, at the same time, the video signal is also stored in the memory section 2d in parallel.

The memory unit 2d is designed to store digital data in units of 8 bits due to the circuit requirements of the entire system, and the video signal input as a serial signal is passed through the serial/parallel converter 2b once and converted into 8-bit data. The data is exchanged with a parallel data signal and transferred to and stored in the memory section 2d.

Then, in response to a command from the console 7 and a control signal from the control processing device 6, the video signal stored in the switching section 2d is switched and outputted instead of the bypassed video signal. The parallel/serial converter 2c converts the stored 8-bit parallel data signal into a serial signal and outputs the serial signal. At this time, the memory scanning control section 2e sequentially scans the memory section 2d corresponding to each line of the document,
The output is displayed on the screen of the display unit 5, but if the scanning speed of the memory section 2d is set to 1/2 speed, 1/3 speed, etc. according to the specification from the console 7, it is easy to display one row (or column) each. can be divided into multiple rows (or columns). However, in this embodiment, row (or column) division is performed mechanically by controlling the scanning speed, so
The uneven number of characters in one row (or column) is not taken into consideration.

The character lines (or columns) written in the manuscript do not necessarily match the lines (or columns) that you want to finalize by editing. While humans judge this appropriately,
Of course, it is possible to edit rows (or columns) by combining or dividing them. However, it goes without saying that if this can be done automatically and the manuscript image can be created, the fair copying work will become much easier. In order to perform such processing, it is sufficient to have a function that can extract character lines (or columns) on a document as lines (or columns).
In the above-mentioned embodiment, by controlling the scanning speed of the memory section 2d, each line of the original can be divided into multiple lines and displayed, and the lines can be matched with the lines (or columns) to be finished as appropriate. be able to.

The data line to the memory section 2d is in the form of a bus in microcomputer systems in consideration of transfer to other sections. Further, the memory scan control section 2e can receive a scan timing signal from the display scan control section 3, and can also be coupled to the address bus of the system. Furthermore, the memory scan control section 2e is also coupled to supply a control signal for changing the scan speed without using a special control line, so that this can be done using the data bus of the system. .

The display data memory section 8 (FIG. 1) may be considered blank at the start of work. Enter FF _H (all 1), etc. as data for all blank spaces. The display data memory section 8 includes a character generation circuit section 9.
Address information for specifying a certain character within is stored, but by entering FF _H etc. in advance, it can also be used to determine whether data has been stored or not. This is detected at the location where the data is stored, and under the control of the video signal switching control section 4, the corresponding section is switched from the video information memory section 2 to the character generation circuit section 9, and the data is displayed according to the work. The output from the character generating circuit section 9 is sent to the device 5. At this time, the image of the document may be completely erased, but the contrast may be lowered to suppress its display.

That is, here, the image of the original and the processing output are displayed simultaneously on the screen of the display device 5 in a superimposed manner, and part or all of the image of the original is suppressed or erased as necessary.

In addition, in this embodiment, a method of outputting and displaying the created character strings via the character generation circuit section 9 was shown as a method of storing and displaying them, but a graphic display method having a dot-by-dot display function may also be adopted. . In this case, the character generating circuit section 9 in FIG. 1 is a memory for graphic display, and the character generating circuit is separately provided inside the control processing device 6. The display data memory section 8 may have the same function as described above, but operations such as accessing the character generation circuit section 9 are no longer necessary.

<Effects of the Invention> As described above, according to the present invention, an image of a manuscript to be drafted or referenced and a processing output generated by console operation are superimposed and displayed at the same time, and can be displayed as necessary. The image of the original document is suppressed and erased as appropriate, making it easier to create and edit documents, and without causing any difference in display color between the original document and the screen, thereby eliminating strain on the eyes. Further, if each row (or column) of the original is divided into a plurality of rows (or columns) and displayed so as to match the row (or column) to be finished, the copying work becomes easier and more convenient.
