Description

How to set reading area using grid chart.

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 chart of an entire readable area size provided in a specific format on a display. The present invention relates to a method of setting a read area using a grid chart that can effectively reduce reading time by directly comparing a chart) with an actual original area located on grid coordinates on a scanner and designating the actual read area on the grid chart.

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, after reading the read data at high speed through a pre-scan in order to obtain the overall form information of the original to be read at a low resolution of about 75 dpi (dot per inch), and then combined display, When the user selects a desired area by displaying the read data on a monitor of a personal computer, the user reads the selected area again at the resolution selected by the actual user and finally the desired area. Perform data reads for.

Another conventional read area setting method employs 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 display to delete outside the area of the desired original.

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.

In order to overcome the above-mentioned problems, the Korean patent application No. 96 recognizes the coordinates of the read area in the grid coordinates on the scanner and sets the same coordinates by the user's key input to read only the desired specific area at the actual resolution selected by the user. -67322 Although the applicant of the present invention has previously filed a method of setting a read area using grid coordinates, in the method of setting a read area using Korean patent application No. 96-67322, which was previously filed, as described above, the read area on the grid coordinates of the scanner After recognizing the coordinates for, the setting of the reading area by the user's key input does not provide a graphical interface on the display.

Accordingly, the present invention has been made to solve such a problem, and in order to speed up the reading speed, a grid chart of the size of the entire readable area provided in a specific format on the display and the actual original area located on the grid coordinates on the scanner are provided. It is an object of the present invention to provide a method of setting a read area using a grid chart that allows a user to directly read a specific area designated on a display at a real resolution selected by a user by directly specifying the actual read area on the grid chart.

In order to achieve the above object, the method of setting a read area using a grid chart according to the present invention, in setting the read area of the scanner, recognizes horizontal and vertical coordinates of the read area on the grid coordinates of the scanner, By comparing and setting the actual read area on a grid chart of the entire readable area size provided in a specific format, it is possible to quickly and accurately read a specific area desired by the user at the actual resolution selected by providing a graphical interface on the display. It is characteristic.

First, prior to explaining the configuration and execution procedure for the read area setting method using the grid chart according to the present invention, a brief description of the method of the scanner, a large flat-bed method of the scanner 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 employing a 128-dot CCD, when the document is A4 (210 mm x 297 mm), the number of dots is 2551 dots x 3507 dots when read at 300 dpi. As described above, a technique is known in which the entire area is divided into 27 shuttle blocks for reading.

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 a grid chart according to the present invention will be described with reference to FIG. 2.

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

In the read area setting method using the grid chart according to the present invention, as shown in FIG. 2, in the read area setting method of improving the read speed by limiting the read area of the scanner to a required area, the operation mode is a read mode (scan). mode), forming a grid chart having a total readable area size on a display and determining whether the read area is the same as the total readable area (S100); If the read area is not the same as the entire readable area, the read area coordinates, which are horizontal and vertical coordinates with respect to the read area, are recognized from the grid coordinates of the scanner, and the grid chart on the display is compared with the read area coordinates. After setting the read area in the grid chart, the read in the desired resolution And selection takes a dock area reading step (S200), when the reading area is equal to the entire read area, consists of a full reading step (S300) takes poison the entire reading area.

Here, the grid chart forming and reading region determination step (S100) may include an operation mode determination step (S110) of determining whether the operation mode is a read mode and a determination result of the operation mode determination step (S110). When the mode is confirmed, the grid chart forming step (S120) of forming a grid chart having a total readable area size on a display and a read area determination step of determining whether the read area is the same as the total readable area ( S130).

In addition, in the selective reading step S200, when the reading area is not the same as the entire readable area as the determination result of the reading area determining step S130, the horizontal and vertical directions of the reading area in the grid coordinates of the scanner are determined. Read area coordinate recognition step (S210) of recognizing a read area coordinate, which is a coordinate, a read area setting step (S220) of setting a read area in the grid chart by comparing the grid chart on the display with the read area coordinates, and reading start According to a command, a selected region read performing step (S230) of reading the read region at a desired read resolution is performed.

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

First, the grid chart formation and read area determination step (S100) determines whether the operation mode is the read 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 determined that the mode is in the grid chart forming step (S120), a grid chart having a size of the entire readable area is formed on the display. In the reading area determining step (S130), the read area is the same as the entire readable area. Determine whether or not.

In the selective reading step S200, when the reading area is not the same as the entire readable area as a result of the determination in the reading area determining step S130, in the reading area coordinate recognition step S210, the grid reading of the scanner may be performed. When the read area coordinates, which are horizontal and vertical coordinates with respect to the read area, are recognized and the read area coordinates are set in the read area setting step (S220) and the read area coordinates are set, the read area is set in the grid chart. In the read operation step S230, the read area is read at a desired read resolution according to a read start command.

On the other hand, if the read area is the same as the entire readable area, in the full read step (S300), the entire original area is read by reading the entire readable area.

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. .

Similarly, grid charts on a display can also be used to form coordinates on other displays, i.e., by forming grid charts, grid sheets, rulers, grids, etc., on the display that provide a measure for the vertical and horizontal directions. Can achieve the purpose.

As described in detail above, in the read area setting method of improving the read speed by limiting the read area of the scanner to the required area, the display apparatus recognizes the horizontal and vertical coordinates of the read area on the grid coordinates of the scanner, and then displays the read area. According to the method of setting a read area using a grid chart according to the present invention, which compares and sets an actual read area in a grid chart of a total readable area size provided in a specific format on a display, a graphic interface is provided on a display. By quickly and precisely reading a specific area of interest at the actual resolution selected by the user, it is possible to effectively reduce the time wasted by reading even the area of the original that the user does not want, and to eliminate unnecessary operations such as prereading, rereading, and editing removal. As you can You can improve the user experience of the product.
