Description

How to set reading area using grid coordinates.

The present invention relates to a method for setting a read area of a scanner, and more particularly, in setting a read area of a scanner, a grid capable of effectively reducing the actual read time by designating coordinates for a desired read area on a grid coordinate. The present invention relates to a reading area setting method using coordinates.

Scanners (ie, reading means) are the most common means of reading letters, pictures, etc. in the form of prints, photographs, and handwritten notes.The scanners, fax machines, computers for computer added design (CAD) It is an essential component such as recognizer.

In recent years, the demand for office automation equipment such as printers, scanners, and fax machines has been rapidly increasing, which has been increasingly developed at the crossroads of office automation. Each office automation equipment has been developed with high performance to expand its own functions. In addition, by independently developing each office automation device used independently, a product that performs a complex document output function while reducing economic burden and installation space for a user is being produced and provided. A device providing such a compound document output function is generally called a multifunction device. Today, a multifunction device has become a typical example of a device employing a scanner.

The present invention is directly related to the method of setting the read area of the scanner. Here, the description of the multifunction apparatus, which is a representative example of a device employing the scanner, will be weak, and the method of setting the read area according to the prior art will be described. do.

In the case of a scanner according to the prior art, it is most common to adopt a pre-scan function as a method for reading a part of an original to be read.

That is, in order to acquire the overall form information of the original to be read at a low resolution of about 75 dpi (dot per inch), the read-read data is read at high speed through a pre-scan, and then combined PC (Personal) When the user selects the desired area by displaying the read-out data on a monitor of a computer), the data is read out for the desired area by performing another read on the selected area at the resolution selected by the actual user. Perform

Another conventional read area setting method adopts an editing method that reads the maximum read area at the actual resolution selected by the user, and then displays the read data on the monitor of the combined PC and deletes it outside the desired original area. I use it.

However, in the conventional method of setting the read area, the former uses the pre-read concept to compensate for the shortcomings of the read speed. However, after the read-out is performed at a low resolution, the read-out is again performed at the resolution selected by the user. There is a primary inconvenience of performing a re-scan, and there is a drawback that a large amount of time is wasted depending on the interface method of a PC as a preparation time for reading a desired area of a manuscript.

On the other hand, the latter method is a method of editing after reading at the actual resolution, which is a very inefficient method of spending excessive time by scanning the entire readable area to read data of a specific area in the original.

In addition, the reading area setting methods according to the related arts do not read an original, even if the user does not want to read the original, and the original does not exist when the actual original size is smaller than the entire readable area. There is a problem that even an area is unnecessarily read.

Accordingly, the present invention has been made to solve such a problem, and in order to speed up the reading speed, by recognizing the coordinates of the reading area in the grid coordinates on the scanner and setting the same coordinates by the user's key input, only the desired specific area is desired. It is an object of the present invention to provide a read area setting method using grid coordinates that can be read quickly and accurately at a real resolution selected by a user without performing a pre-read.

In order to achieve the above object, the reading area setting method using the grid coordinates according to the present invention provides a chart that can easily recognize a position such as a grid sheet in setting the reading area of the scanner. After the horizontal and vertical coordinates of the read area are recognized on the grid coordinates, the read area is limited to the required area by setting the same horizontal and vertical coordinates by the user's key input on the read drive software. The specific reading area desired within the available area may be read at a desired actual resolution without a prior reading.

First, prior to explaining the configuration and execution procedure of the read area setting method using grid coordinates according to the present invention, a brief description of the method of the scanner, the method of the scanner is a flat-bed (flat-bed) method And the sheet-feed (sheet feed) method is divided into two, the most recent of the former method of the shuttle scan (shuttle scan) method is introduced to help understand the scanner method.

FIG. 1A is an exemplary diagram illustrating a shuttle block division method for A4 paper, and FIG. 1B is an exemplary diagram illustrating a reading method for a single shuttle block.

For convenience of understanding, looking at a specific example of the shuttle reading method, the CCD (Charge Coupled Device) used in the shuttle scanner module is a typical example using a 128-dot (CCD) CCD.

In the case of the shuttle read type scanner adopting a 128-dot CCD, when reading documents at A4 (210 mm x 297 mm) format, the number of dots is 2551 dots x 3507 dots when reading at 300 dpi, as shown in Fig. 1A. The technique of reading out by dividing the whole area into 27 shuttle blocks is known.

Accordingly, the read method for each single shuttle block reads one line in the vertical direction, as shown in FIG. 1B, and then moves horizontally by a carriage return motor (CR motor), followed by a vertical line. The data read for a single shuttle block is completed by repeating the operation of reading data.

This same reading method for a single shuttle block is repeatedly applied to the subsequent shuttle block in the same manner, thereby overcoming the problem of low resolution CCDs using limited resources (i.e., 128 dot CCD) and reading the entire data of the original to be read. You can finish it.

Hereinafter, a method of setting a read area using grid coordinates according to the present invention will be described with reference to FIG. 2.

2 is a flowchart illustrating a read area setting method using grid coordinates according to the present invention.

In the reading area setting method using grid coordinates according to the present invention, as shown in FIG. 2, if it is confirmed that the operation mode is the scan mode, whether or not the reading area is a part of the entire original area; As a result of the determination of the read area determination step (S100) and the read area determination step (S100), which determine whether the read area is the same as the entire readable area, the read area is a part of the entire original area or the same as the readable area. If not, the read area coordinates, which are horizontal and vertical coordinates with respect to the read area, are recognized on the grid coordinates of the scanner, and then the read area coordinates are set by a user's key input to the read drive software to read the read at a desired resolution. Selected reading step of reading a region (S200) and the determination result of the reading region determination step (S100), the read If the station is equal to the entire read area, consists of a full reading step (S300) takes poison the entire reading area.

Here, the read region determination step (S100) may include an operation mode determination step (S110) of determining whether the operation mode is a scan mode (S110), and the operation mode is read as a result of the determination of the operation mode determination step (S110). If the mode is recognized, the first read area determination step (S120) of determining whether the read area is part of the entire original area (S120), and as a result of the determination of the first read area determination step (S120), indicates that the read area is the entire original area. In this case, the second read area determining step (S130) determines whether the read area is equal to the entire readable area.

In addition, when the read area is determined as the read area determining step S100, the read area may be a part of the entire original area or not the same as the entire readable area, the read area coordinates on the grid coordinates of the scanner. Read area coordinate recognition step (S210) for recognizing, read environment setting step (S220) for setting the read area coordinates and read resolution by a user's key input to the read drive software, and the read in accordance with a read start command In step S230, a selected region read operation is performed to read the read region at a resolution.

An operation procedure of the read area setting method using the grid coordinates according to the present invention configured as described above will be described in detail with reference to FIG. 2.

First, the read area determination step (S100) determines whether the operation mode is a scan mode in the operation mode determination step (S110), and as a result of the determination of the operation mode determination step (S110), the operation mode is read. If it is recognized that the mode is in the first read area determination step (S120), it is determined whether the read area is a part of the entire original area, and as a result of the determination of the first read area determination step (S120), the read area is the entire document. In the case of the region, the second read region determination step (S130) determines whether the read region is the same as the entire readable region.

As a result of the determination of the read area determination step (S100), when the read area is a part of the entire original area or is not the same as the entire read area, the selective read step (S200) may be performed on the read area on the grid coordinates of the scanner. After reading the read area coordinates that are the horizontal and vertical coordinates, the read drive software reads the read area at a desired resolution by setting the same horizontal and vertical coordinates (ie, read area coordinates) by a user's keystroke in the read drive software. As a result of the determination of the read area determination step (S100), when the read area is the same as the entire readable area, the full read step (S300) reads the entire original area by reading the entire readable area.

In this case, when the read area is determined as the read area determination step S100, the read area is a part of the entire document area or is not the same as the entire readable area, the read area coordinate recognition step S210. Recognizes the read area coordinates which are the horizontal and vertical coordinates for the read area on the grid coordinates of the scanner at. A read resolution is set, and the read area is read at the read resolution according to the read start command in the selected area read performing step (S230).

In the present invention, a method of recognizing grid coordinates may use means for identifying grid sheets and other coordinates, and may use rulers, grids, and the like, which provide measures for the vertical and horizontal directions. .

As described in detail above, in setting the reading area of the scanner, the horizontal and vertical directions with respect to the reading area on a grid coordinate provided by a chart that can easily recognize a position such as a grid sheet or the like. After recognizing the coordinates, the read drive software sets the same horizontal and vertical coordinates by the user's keystrokes to limit the read area to the required area, thereby pre-reading the desired specific read area included in the entire readable area. According to the reading area setting method using the grid coordinates according to the present invention, which reads quickly and accurately at the actual resolution desired by the user, it is possible to effectively reduce the waste of time caused by reading even the area of the original that the user does not want, and read and reread. Omit unnecessary operations such as editing, removing, and editing Depending on that can improve the user experience for scanner-related products.
