[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image input / editing apparatus, and more particularly to an image input / editing apparatus which handles inputting / editing of image data.

[0002]

2. Description of the Related Art Present image input means include image scanners and television cameras (electronic cameras). Further, there is an OCR or a bar code reader as a device for outputting a figure or a character by combining image input and editing. This is for processing the read digital image data, converting it into a figure or character code, and outputting it. However, in these conventional copy type image scanners, Japanese Patent Application Laid-Open No. 4-245 has been proposed.
As disclosed in U.S. Pat. No. 767, the reading unit and the display unit are separately configured, and there is a drawback that the read document and the display content cannot be compared in real time. Therefore, it is necessary to read the same document many times for alignment of input images.

As a method for solving such a problem, it is possible to prevent an input error of an original by using an image input device using a transmissive display as disclosed in Japanese Patent Laid-Open No. 4-245767.

[0004]

However, the above-mentioned conventional method is intended to prevent the input error of the original document, and to visually overlap the original document to be read and the already read portion of the original document. Limited to prevent reading mistakes. Therefore, it is still impossible to simultaneously perform the editing process such as pasting on the previously read image data to form one image data at the same time when reading the document.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an image input / editing apparatus which can easily perform editing processing such as data pasting processing when reading a document.

The number of passing images is counted to detect the position of the image input unit 12 on the transparent thin display 11. That is, the position detecting slit 20 and the position detecting sensor 24 constitute a position detecting means.

This transparent thin display 11 is shown in FIG.
It is composed of a liquid crystal display (hereinafter referred to as LCD) panel 25 as shown in FIG. The LCD panel 25 is configured such that non-display pixels are transparent without using a color filter.

The LCD panel 25 is driven by an LCD drive section as shown in FIG. Ie LCD
Under the control of the controller 26, when the digital image data for one scanning line read from the frame memory 27 is input to the X driver 28, the voltage corresponding to each pixel of the LCD panel 25 is input to the X driver 28. Retained.
Then, it is supplied to each data line of the LCD panel 25. At that time, when the scan pulse is applied from the Y driver 29 to the scan line of the LCD panel 25, the voltage corresponding to the digital pixel signal is written in all the pixels on the scan line to display the pixel. .

An image of one frame is displayed on the LCD panel 25 by sequentially performing the above-described operation for all scanning lines.

In this embodiment, an ordinary microprocessor is added with an image input unit, and each component has a function for handling an image. Main memory is RAM
Etc., and stores read data, various processed data, and the like. The program memory is composed of a ROM or the like, and stores a control program for the CPU and the like.

In this embodiment, the display section is composed of an LCD panel which is a transmissive display and an LCD drive section. Display data obtained based on the image data stored in the main memory is stored in the frame memory. The image input section is composed of a light source array and an image sensor array, and manually scans the document along the back surface of the LCD panel constituting the display section as described above.

The pointing device control unit displays the position designated by the tablet unit on the display unit based on the position information from the tablet unit including the tablet and the stylus. In the embodiment of the image input / editing apparatus having the above configuration, the original is read and edited by the following operations.

The transparent thin display 11 constituting the upper lid of the above apparatus is opened, and the original 23 is placed on the back cover 13 to close the transparent thin display 11. Thus
As shown in FIG. 1, the frame 1 of the transparent thin display 11
The manuscript 23 is sandwiched between the Nos. 4 and 10 and the back cover 13. At that time, the image input unit 12 is aligned with the reading start position of the document.

First, as shown in FIG. 3A, the light emitted from the light source array 21 housed in the image input section 12 is reflected on the back surface of the original 23 to be reflected by the image sensor array 2.
It is incident on 2. And the image sensor array 22
The image signal representing the light and darkness of the reflected light from the original input to the document is converted into an electric signal by the image sensor array 22, and the image data for the first one scanning line is obtained and stored in the main memory 30. At the same time, the position detecting slit 2 detected by the position detecting sensor 24.
Based on the position information based on the number of 0s, the main CPU determines that the image data for one scanning line obtained at present is the data for the first scanning line. Then, the obtained first data is subjected to processing such as enlargement / reduction by the CPU, and is written in a predetermined address of the frame memory based on the position information.

The data thus written in the frame memory is read out in real time by the LCD controller 26 (see FIG. 5). Then, based on the position information, it is displayed at the same position as the position of the image input unit on the LCD panel 25 (the transparent thin display 11 in FIGS. 1 to 3 and the display unit 33 in FIG. 6).

Next, a finger is pressed against the finger contact portion 19 of the scan lever 16 shown in FIG. 1 to move the image input portion 12 in the direction of the arrow.
Slide. At the same time, the position detection sensor 24 detects the number of the position detection slits 20 accompanying the movement of the image input unit 12, and the position information of the image input unit 12 is obtained. Then, the image data of the next one scanning line is obtained by the image input unit 12 in synchronization with the obtained position information and stored in the main memory. Then, after various scanning is performed, the image data for one scanning line is written in a predetermined address of the frame memory based on the position information. The data is read from the frame memory by the LCD controller and displayed in real time at the same position as the position of the image input unit 12. Hereinafter, by sliding the image input unit 12 in the arrow direction shown in FIG.
The above operation is repeated, and the original image is completely read and displayed. At that time, since the LCD panel 25 is formed to be a transmissive type, the original 23 can be made to be visible as it is in the pixel portion of the LCD panel 25 where the image is not displayed. Therefore, as shown in FIG. 7, the portion of the original that is transparently visible on the LCD panel 25 and the data that has been required to be edited (such as pasting) are attached to this original at the same time. It can be seen, and these can be configured together as if it were one piece of data.

FIG. 7 is a diagram for explaining a state in which the original is transparent.

As shown in FIG. 7, the LCD panel 25 described above is used.
Since it is possible to simultaneously see the area 40 portion (data to be attached to the original image) and the area 41 portion (original material that is seen through) in the area, it is possible to instantly know the data attachment state when inputting the original, and It is possible to prevent the situation of inputting again.

Further, when the input valid area of the original is designated in advance and a means for blocking the area other than this area from the original is provided so as to prevent transmission of the area other than this area, the same applies when only one part of the original is desired to be input. Can be input and edited.

FIG. 8 is a diagram for explaining inputting only one part of the document, and FIG. 9 is a diagram showing the document when only one part of the document is input.

When you want to take out only one part of the original,
An example of this portion is shown in FIGS. That is, FIG. 8 shows an example in which only one part of the original document 43 is input. At this time, the manuscript input effective portion 4 is displayed on the display screen.
2 is designated, the document is placed under the display surface as in the conventional case, and the document is input by the scanner. FIG. 10 illustrates this.

FIG. 10 is a diagram showing that the document is placed on the back surface of the LCD, FIG. 11 is a diagram illustrating that a shutter function is provided between the LCD and the document, and FIG. 12 is a diagram illustrating the shutter function.

In FIG. 10, the original document 44 is placed under the LCD panel 25, and a part of the document before input is seen through the document input portion 45. here,
In order to prevent the document from being transmitted to the portion 46 of the display surface other than the document input portion 45, as shown in FIG. 11, the shutter 4 that prevents the transmission between the document input portion 45 and the document 44.
Insert 7. In the case of this example, the shutter 47 has a shape as shown in FIG. That is, the hole 48 is opened in the center only in the same size as the document input portion. The other portion 49 is the same as the white paper, and the transmission state is blocked.

FIG. 13 is a diagram for explaining another shutter function. This shutter is, for example, 50 as shown in FIG.
By stacking four partial areas such as Nos. 53 to 53, a blank having the same size as the area 48 can be formed.

FIG. 14 is a diagram for explaining a component having a shutter function. That is, FIG. 14 is a development of the four partial areas.

In this case, too, the data to be edited with the input original (that is, the data display portion 4 in FIG. 7).
If it is only necessary to know where 0) exists at the time of inputting the original, all the display data of the original transmitting section 41 is turned off (transmissible state) at the same time when the original is input, and the data of the data display portion 40 is turned off. By setting all the switches to ON (non-transmissive state), the state of the shutter function described above can be created.

Also, another LCD panel can be used as a shutter function by stacking another LCD panel separately from the one for display. That is, the LCD panel is also used for the portion 47 in FIG.

Further, for the document input portion, the conventional image input device method is used to display the already-input data in the already input document portion of the document input section,
A transparent original can be seen in the original portion before input.

FIG. 15 is a diagram showing a state when a document is input. In FIG. 15, a portion 60 shows the data that has been input before, a portion 61 shows the portion of the document that has already been completed and is displayed, and a portion 62 shows the state where the document portion before the input is seen through.

Further, by making the following two modes switchable, it is possible to deal with the case where it is desired to carry out the laminating process after enlarging / reducing the original.

Mode 1: Method in which the input original and the read data are visible at the same time (conventional method) Mode 2: Method in which the input original and the data to be edited such as pasting processing are visible at the same time Select which mode to use. If the input status is Mode 1, LCD
To make all transparent. In the original input start state, only the contents of the original can be seen. Next, each time the document is read, the data at the corresponding address in the frame memory is rewritten, and the data is displayed on the LCD in real time. Therefore, the original before being read and the read state of the original can be seen at the same time, and the input results can be compared. When it is necessary to perform an editing process such as pasting with other data, it is performed after the document is input.

If the input state is mode 2, the original input portion is made transparent so that the original can be seen transparent. Data is displayed for other parts. The processing at the time of inputting a document is the same as the above-described processing method.

In this way, one of the two modes can be appropriately selected when the original is input.

Further, when enlarging or reducing data at the time of inputting an original, there is also a method of obtaining an effective portion of the input original from the input area of the original designated on the display screen based on the enlargement ratio or reduction ratio of the data. is there.

16 and 17 are explanatory views when an enlargement function is accompanied when a document is input.

An example at this time is shown in FIG. First, what part of the display screen the document should be input is shown. Figure 1
In the example of No. 6, it corresponds to the document data insertion portion 66. The system displays the document input effective portion 65 corresponding to the enlargement ratio and the reduction ratio from the designated area. FIG. 17 shows this state. By designating this area, the user can know which part of the data is in which area of the display screen when the document is input. The example of FIG. 16 shows the case where the input document is displayed in an enlarged manner. In the method of obtaining the portions 66 to 65, the effective area (effective portion) for the input document can be obtained by multiplying by the reciprocal of the enlargement ratio.

FIG. 18 is a diagram for explaining a calculation method when an enlargement function is involved in inputting a document.

In FIG. 18, IH and IV are part 6 respectively.
5, width, height, HH, and HV are the width and height of the portion 66, respectively.

For example, when the enlargement ratio is α (α <1 when reduced display), the size of the portion 65 with respect to the portion 66 is IV = HV / α, IV = HV / becomes α.

Further, regarding from which portion the portion 65 is to be displayed, regarding the difference between the portion 65 and the portion 66, SH = (IH-HH) / 2, SV = (IV-HV) /
It can be obtained from the calculation formula of 2.

FIG. 19 and FIG. 20 are state diagrams when a reduction function is accompanied when a document is input.

When reducing the input document data,
As shown in FIG. 19, by designating the portion 70 into which the data of the original is to be inserted on the display screen, the user can be notified of the input original valid portion 71 shown in FIG. Based on the part 71, the user can see the part to be input through the original before input. However, since the portion 71 inevitably becomes larger than the portion 70 when the reduced display is performed, when the user sees the original transparently, the necessary display data can be seen for the portion where the portion 71 is larger than the portion 70. It's gone. Therefore, in this case, the manuscript data need not be displayed while being input (the method used in FIG. 15 is not used) and displayed after all the input is completed. If the user wants to see the document while inputting it, a method of switching the input mode may be used. In this way, expansion of input data,
When reduction is involved, either method can be used depending on the preference of the user.

Further, as an application of this, for example, the portion 71 in FIG. 20 is made visible at the same time while inputting a document similar to the conventional method, and after all the input is completed,
There is also a method of reducing the data of the portion 71 to the size of the portion 70. At this time, before inputting the document, the portion 71-the portion 70
It is necessary to save the display data of the above from the frame memory to the main memory and restore the original display data after the document is input. Further, character recognition, translation function, etc. can be added as an editing function as in the conventional device.

[0053]

The transmissive display unit is configured to display an image to be read by the image input unit at the same timing as another image read by the image input unit before the image to be read is read. And a first mode in which the controlling device allows the original to be transmitted through the transmissive display unit, and an image to be read by the image input unit and another image read by the image input unit before the image to be read is read. Since the operation of the image input unit and the transmissive display unit is controlled so that the image is displayed on the transmissive display in either one of the second modes which are displayed at the same timing, the image to be read by the image input unit is You can see other images at the same timing, that is, you can visually overlay them, and you can easily edit and paste from the original input. Get done.
