Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, when enlarging and displaying a part of image data, automatically moves the display area of the enlarged image along a row of sentences so that the user can write consecutive sentences. The present invention relates to an image display device in which the user does not have to perform an operation for moving the enlarged window when reading.

[0002]

2. Description of the Related Art Conventionally, when displaying image data,
If a character cannot be discriminated by displaying the entire document in a reduced size and reducing the size of the document, the user performs an operation such as reading an unreadable part using a display window for enlarging a part of the character.

[0003]

In the above-mentioned conventional apparatus, when there are a large number of unreadable characters in a row, it is necessary for the user to move the target area for enlarged display. There was a problem.

Therefore, the present invention has been made in consideration of the above-mentioned circumstances, and when the image data is enlarged and displayed, the display source area of the enlarged display window is automatically moved along the line of characters to be continuously displayed. It is an object of the present invention to provide an image data display device capable of reading image data enlarged in size.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an image document display device having a window capable of enlarging and displaying a part of an image document, for storing the entire image data. The image data storage means and the character string cutout device capable of cutting out the character string of each line are provided, and the target area of the enlarged window is automatically moved along the text written in the image document. The image document display device is characterized in that continuous reading can be provided to the user.

Further, in order to achieve the above-mentioned purpose, in the above-mentioned image display device, when the end of the sentence in the display page is detected, if there is a page following the page, move to the next page. Then, the enlarged window is automatically moved again to the page.

Further, in order to achieve the above-mentioned purpose, an image document display device is provided with a character recognizing means for recognizing a character from the cut out image data and a voice synthesizing means for uttering the character string from the character string data. By providing
The present invention is an image display device characterized by moving and displaying while reading out a character string that is being enlarged and displayed.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The outline of the present invention is as follows. (1) An image data storage device for storing the entire image data in an image document display device having a window capable of enlarging and displaying a part of the image document,
By installing a character string extraction device that can extract the character string of each line, the target area of the enlarged window is automatically moved along the text written in the image document, and the user can read the text continuously. It is an image document display device that can be provided.

(2) In the above (1), when the end of the sentence in the display page is detected, if there is a page following the page, the page is moved to the next page and the page is re-entered. An image display device that automatically moves the enlarged window.

(3) By providing a character recognition device for recognizing a character from the cut-out image data and a voice synthesizer for uttering the character string from the character string data, while reading out the character string currently being enlarged and displayed. Image display device for moving and displaying.

The above is the outline of the present invention. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing the main components of the present invention.

A CPU (central control unit) 10 controls various controls. Reference numeral 11 denotes a ROM (read-only memory), which is a storage device for storing the program of the CPU 10, fixed data, and the like.

12 is a RAM (random access memory)
That is, the work of various data, the program information, and the like are stored. An input control unit 13 controls input from a keyboard, a mouse, or the like.

An external storage unit 14 stores image data and the like. An image data storage device 15 stores the entire image data.

An image data transfer device 16 transfers an arbitrary part of the image data to the window control device 17. A window controller 17 opens a plurality of display windows to display the transferred data.

Reference numeral 18 is a character string slicing device, which generates the coordinates of the character string area in units of one line from the image data. A character recognition unit 19 generates character string data from the cut image data.

Reference numeral 20 denotes a voice synthesizer, which reads out the character string by passing the character string data. The operation of the above configuration will be described below.

FIG. 2 is a diagram showing the operation of the present invention. According to the present invention, when the image document is displayed, the enlarged window displayed to see the unreadable characters is automatically moved along the flow of the characters.

FIG. 3 is a flow chart showing the operation of the present invention. First, the image data of the page to be displayed is fetched from the external storage device 14 and the image is developed in the image data storage device 15 (step S10).
reference).

Next, for the developed image data,
The character string cutting device 18 cuts the character string data from the image data, and takes out the start and end positions of the line of each character string (step S12).

At present, the enlargement display target area is adjusted so that the position of the character closest to the enlargement window target area becomes the center (step S14). At a time interval preset by the system or set by the user,
The target area is moved in the moving direction of the character string by the moving distance set as described above (step S16).

The cut-out image data at the center of the enlarged and displayed area, which has not yet been passed to the character recognition section 19, is passed to the character recognition section 19 (step S18). The character recognition unit 19 passes the encoded character string data to the voice synthesizing device (step S20), and the voice synthesizing device utters the passed character string data.

Then, the updating process of the enlarged window for the moved target area is performed (step S22). As a result of moving the target area, if it is not the end of the cut line (N in step S24), the process returns to the beginning of the loop. If it is at the end (Y in step S24), the enlargement target area is moved to the start position of the next cutout line that is considered to continue (step S26).

If the next cutout line is not found, the target page is changed to the next page, the target area of the enlarged window is moved to the initial position (usually the upper left), and the page expansion is started, whereby The present invention is also realized.

[0025]

As described in detail above, according to the present invention,
When enlarging and displaying the image data, the display source area of the enlarging display window is automatically moved along the line of characters,
It is possible to read continuously enlarged image data. That is, it has an excellent effect that the character string data included in the image data can be continuously read in the enlarged display state.
