Description

  The present invention relates to an image processing terminal that divides an image and prints it on a plurality of sheets when printing a large image displayed on a display screen.

In general, when an image processing terminal prints an image larger than the size of the paper to be printed, the image processing terminal divides the image into a plurality of pieces, thereby printing the plurality of sheets.
A conventional image processing terminal adds an image of a gap to an image when dividing, so that the position when arranging divided images based on the gap can be easily confirmed (for example, Patent Document 1). reference.).
Japanese Patent Laying-Open No. 2005-107822 (paragraph “0051”, FIG. 10)

However, in the above-described conventional technique, if there are characters to be read in the divided part of the divided image, the characters are divided and difficult to read. If the divided portions are not joined after printing, there is a problem that it is difficult to confirm the characters.
An object of the present invention is to provide means for solving the above problems.

  In order to solve the above problem, the present invention is an image processing terminal that divides an image into a plurality of images when the image size is larger than a set size. A storage unit for storing overlapping region information for providing a region overlapping with a certain length from a divided portion between adjacent images with respect to a subsequent image, and when the image is divided, the overlapping region information from the storage unit The first image to be printed is divided into the size of the paper to be used for printing, and other images are provided with an area overlapping with the adjacent image based on the read overlapping area information. A region is divided into the set size.

  As a result, when the divided image is printed, even if the divided portion has characters and the characters are divided, the overlapping characters are divided, so that the divided characters are Therefore, it is possible to check the characters without joining the divided portions after printing.

  Embodiments of an image processing terminal according to the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram illustrating the configuration of the image processing terminal according to the first embodiment.
In FIG. 1, reference numeral 1 denotes an image processing terminal, such as a terminal having a function for creating a drawing or a terminal connected to an Internet line.
A control unit 2 controls each unit of the image processing terminal 1 according to a control program stored in the storage unit 3 to perform printing processing by the printer 7, and also determines the size of the paper to be used and the size of the image to be printed. For this reason, division processing is performed on an image that does not fit on the paper.

  Reference numeral 3 denotes a storage unit that stores a control program and stores processing results by the control unit 2 and also divides the image into a plurality of divided images according to the size of a sheet to be printed when a large image is printed. Information, overlap size information indicating the range of overlap parts (overlapping parts) when adjacent areas are overlapped with a certain length from the divided parts when divided by that division size, etc. Is stored.

Here, it is assumed that the overlap size information includes contents about the pixel, the length, and the resolution.
A display unit 5 includes a display screen such as a CRT or LED and has a function of displaying an image or the like to be printed by the image processing terminal 1.
An operation unit 6 includes a keyboard, a mouse, and the like, and receives an instruction for printing an image displayed on the display unit 5 from an operator.

A printer 7 has a function of printing an image to be printed displayed on the display unit 5.
The operation of the above configuration will be described.
The operator causes the operation unit 6 of the image processing terminal 1 to display an image such as a drawing or various pages on the Internet on the display screen, and inputs an instruction to print the image using the printer 7. In the following description, description will be made using image data (referred to as an image) of a form captured by a scanner or the like.

When the control unit 2 receives an input of a print instruction (for example, inputs to print at A4 or A3), the size of the image to be printed displayed on the display unit 5 becomes the size of the paper to be printed. Then, it is determined whether or not the image fits, and when it is recognized that the image is large, a division process for dividing the image is performed. Here, FIG. 2 is an explanatory diagram showing a state in which the image is divided. Indicates an original image, and (b) indicates a divided image divided into a plurality of parts.

  The control unit 2 reads the division size information and the overlap size information from the storage unit 3 and performs image division processing on the original image shown in FIG. When the divided image b-1 to be printed on the eyes is determined according to the division size, the divided image b-2 to be printed on the second sheet is determined so as to include an overlapping portion overlapping the first divided image b-1. The divided image b-3 that is divided by the division size and printed on the third sheet is divided at a division size that is determined so as to include an overlapping portion that overlaps the second divided image b-2. A divided image is generated by dividing the original image into three.

  In this way, as shown in FIG. 2B, a predetermined width A1 (a portion indicated by hatching) from the right end to the left side after the printing of the first image b-1 is completed is the second sheet. This is an overlap portion with the divided image b-2 to be printed (simply referred to as the second divided image b-2), and the size of the second divided image b-2 with the divided size including the overlapping portion. At this time, the divided image b-3 printed with the predetermined width A2 from the right end to the left side after the printing of the second divided image b-2 is finished on the third sheet (simply the third divided image b-3). It becomes an overlap part with.

The size of the third divided image is determined by a divided size including an overlap portion A2 arranged at the right end of the second divided image.
Here, it is assumed that the width A1 and the width A2 are the same.
The control unit 2 uses the printer 7 to print the divided images generated by the above-described method.
By doing in this way, even if characters are divided at the divided portion of the paper on which the divided image is printed, the divided portion is an overlap portion. Therefore, the printed paper for confirming the divided characters. There is no need to connect the two.

Here, FIG. 3 is an explanatory diagram when the divided image is converted into data in the TIFF format.
When the original image is divided, the control unit 2 collects the data of the divided image into one file in a multi-page format such as the TIFF format.
In FIG. 3, reference numeral 20 denotes a header information section which is attached to the divided image to be printed on the first sheet, and is written with various information such as the print date and the file name of the original image.

21 is a tag information section, 21a is provided in the first divided image, 21b is provided in the second divided image, and 21c is provided in the third divided image, and the overlap in the provided divided images is provided. Size information, information indicating the contents of the image in the overlap portion, and the like are written.
Reference numeral 22 denotes a divided image data portion, which is configured by writing information indicating the contents of the divided image. The information of the first divided image is indicated in 22a, the information of the second divided image is indicated in 22b, and the three pieces are indicated in 22c. Information on the divided images of the eyes is written respectively.

  In this way, when it is desired to confirm the original image after generating the divided image, the control unit 2 recognizes the information of the overlap portion from the tag information unit 21 of the TIFF format data. When the three divided images are arranged so as to be continuous, the overlap portion common to the two divided images overlaps, so one of the overlapping overlap portions is deleted and the three divided images are combined. Thus, the original image can be restored.

That is, the information of the overlap portion of the tag information unit 21 is for restoring the divided image to the original image.
When the divided images are combined and restored to the original image, one of the overlapping portions may be deleted, or the overlapping portions may be overlapped.
Furthermore, when all the images cannot be displayed on the display unit 5 as a result of the restoration to the original image, the images may be restored all at the time of restoration, or the image displayed on the display unit 5 may be scrolled or the like When overlapping portions of the divided images are displayed with the display range shifted, the divided images including the overlapping portions may be arranged to restore the images one after another.

In the present embodiment, the information on the overlap size in the divided image is written in the tag information unit 21, but may be stored in the header information unit 20.
In this embodiment, the image is divided at the time of printing. However, the image may be divided when the image data is filed after the image is acquired by a scanner or the like instead of at the time of printing. At this time, although not specifying the print size such as during printing, which may by setting or previously divided into any size, the preferred size of the image in particular to split the storage unit 3 When storing and filing, the control unit 2 reads and divides the set size stored in the storage unit 3.

  As described above, in this embodiment, when an image is printed in accordance with the size of the paper to be printed by the printer, an overlap portion is provided when the entire image does not fit on the paper and is divided. Therefore, even if a character is divided at the divided part when the divided image is printed, the character is an overlapping part and can be confirmed by referring to another divided image. Therefore, it is not necessary to join the printed divided images in order to check the characters divided at the divided portions.

  In the embodiment described above, an example in which the image is divided into three in the horizontal direction as shown in FIG. 2 has been described. However, the dividing direction is the same for both the vertical direction and the vertical direction and the horizontal direction. The effect of can be obtained.
