The database 110 stores image data and related data associated with the image data. At this time, the data number is automatically stored by the data number generation unit 130 for each data. The barcode generation unit 150 generates a barcode based on the address value information included in the data number, matches the barcode and the corresponding data, and stores the barcode in the database 110. The database 110 stores a member number, a document number, a questionnaire number, a mobile phone number, an e-mail address, etc. in association with the member number.

The image working unit 120 serves to generate image data from a scanning image such as a questionnaire or a study paper. When the image work unit 120 generates the image data from the scanning image, the image data may be generated at a high resolution by expanding the scanning image by a predetermined ratio and generating the image data therefrom. For example, you can magnify a scanning image five times, generate image data, select the part to be saved as image data, and compress the selected part to 100% size again to generate image data. Can obtain 5 times the image data. By securing high resolution image data, it is possible to prevent a problem that the resolution decreases when outputting the image data to the problem paper 10.

The operator may select a portion of the scanning image to be extracted as image data by using a device such as a mouse or a trackpad, and the portion selected by the user is stored in the database 110 as image data. The image work unit 120 may call image data stored in the database 110 and may assign predetermined coordinates to allow a learner to input a correct answer. For example, if the image data is a multiple-choice problem, the coordinates are given to the view portion, and the learner may input the correct answer by selecting the view portion to which the coordinate is given.

The data number generation unit 130 generates a data number by combining an invariant code and a variable code in image data and related data stored in the database 110. The invariant code is a code that is automatically generated according to the information when the image data and related data are input, and the variable code is a code that the operator grasps the contents of the image data and related data and selectively gives it. In particular, the address included in the data number may be used to identify the data, the address value may be stored in the barcode generated by the barcode generator 140. The questionnaire generating unit 152 rearranges the image problem based on the code included in the data number to generate the questionnaire.

The barcode generation unit 140 generates a barcode that stores an address value for identifying each data, and stores the generated barcode by matching the image data and related data stored in the database 110. Alternatively, the URL address is recorded in the bar code, so that the Internet can be used without the operation of the information providing terminal. The barcode generation unit 140 may generate data information barcodes that store instructions related to reproduction of video and sound sources, as well as barcodes that store address values for accessing image data and related data. That is, the user can control the information providing terminal 20 remotely through the barcode scanner 30 by storing the play, stop, rewind, fast forward, and pause command address values of the basic player used when playing a video and a sound source in a barcode. can do.

The problem management unit 150 reconstructs the image data of the database 110 and outputs it to the questionnaire 10, and receives a solution of the questionnaire 10 as input to the input device 40 and compares the score with the correct answer of the database 110. The result is stored in the database 110. The problem paper 10 may be a paper printed matter output through a printer or an electronic document that may be displayed on the information providing terminal 20.

The incorrect note generator 160 reconstructs image data selected from the database 110 according to the scoring result and outputs the incorrect note through the printer.

In this embodiment, the problem management unit 150 or the incorrect note generating unit 160 has been described to provide a problem paper 10 or an incorrect note through the printer, but the problem paper 10 or incorrect note is printed through the printer. It is not limited to. For example, the questionnaire 10 or incorrect answer note may be provided to the member in electronic form through the information providing terminal 20 forming the wired or wireless network. In this case, the answer sheet 10 may be input to the image data image data database system 100 in an electronic form through the information providing terminal 20 connected to the network.

As illustrated in FIG. 4, item 01 contains four views from (a) to (d). At this time, the spatial coordinates can be given to the viewing areas of (a) to (d) so that each view can be selected using a mouse. In this case, the spatial coordinates of the viewing area may be coordinates divided into at least four. In the area of the image data, if (a) is the distance from the upper left corner x in the longitudinal direction and y in the height direction, the coordinates of (a) can be expressed as 1: x: y: 0: 0. In this case, the first 1 means the first view, and is sequentially increased by 1. Since the coordinates of (b) are the same in the longitudinal direction with (a) but only in the height direction, the difference in the longitudinal direction with (a) can be expressed as 2: x: y: 0: z have. That is, the first number 2 means the second view, and x: y means the coordinates of the first view to which the reference is based (that is, the coordinates of the view (a)). 0 means no difference in the longitudinal direction from the first bogie, and z means that it is z apart from the first bogie in the height direction. Based on this, if the coordinates of (c) and (d) are determined, the coordinates of (c) are 3: x: y: 0: z ', and the coordinates of (d) are 4: x: y: 0: z' '. can do. In this case, z 'means height difference between (a) view and (c) view, and z' 'means height difference between (a) view and (d) view.

This embodiment is not intended to limit the present invention, and may include various methods for expressing spatial coordinates in image data. For example, (a) and (b), (b) and (c), (c) and (d) give coordinates using the same lengths in which the views are all apart, or display each view in a matrix, It may be. Alternatively, a predetermined reference point may be set in the image data, and the coordinate may be given based on the coordinates and the difference of the reference point.

By setting the constant area coordinates in the image data as described above, the user can input the answer by selecting the spatial coordinates using the input device 40, for example, a mouse.

The data number generation unit 130 generates a data number by combining an invariant code and a variable code in image data and related data. Invariant codes are codes that are automatically generated according to the information when the image data and related data are input, and variable codes are codes that the administrator grasps the contents of the image data and related data and selectively assigns them.

Invariant codes are generated sequentially in the order of input, indicating the address value of the data, the source ID representing the working computer of the data, the worker displaying the worker information of the data, and the creation date indicating the entry time of the data. Contains information about

Variable codes include codes such as data type, output page, output sequence number, title, keyword, correct answer, scoring, problem type, subject information, connection information, and bar code printing. The data type corresponds to any of the input data: image data, commentary associated with image material, knowledge information associated with image material, script associated with image material, sound source associated with image material, or video associated with image material. Used to distinguish between For example, type P may be used for image data, A for commentary, K for knowledge information, S for script, M1 for sound source, and M2 for separator. The output page indicates a page to be output when the corresponding image data is to be printed in question paper, and the output order number determines the output order in the corresponding page.

The title is a code that can distinguish the image data by inputting the subject or headline of the input data. A keyword is a field for inputting an index word for an administrator to easily search for a problem according to a problem that is difficult to recognize a text of an input image data. In the correct answer, the correct answer of the image data is entered, and in the score, the score of the corresponding image data is recorded, so that the user can provide the status of noon and the scoring status of the answer. The problem type is to distinguish whether the image problem is multiple choice or short answer, and the subject information is to distinguish whether the input material is about a subject such as English listening, English grammar, mathematics, or Korean. If the input material is an image problem, the connection information may include the address of the commentary, script, sound source, and video material associated with the material. Whether to print the bar code is to decide whether to print the bar code that stores the address value of the commentary, script, sound source, and video data associated with the data, along with the image data. For example, if a T (True) value is given in the bar code output field, the bar code is printed together with the image data when printing the problem paper. If the F (False) value is given, only the image data is printed as the problem paper. The image data and related data are stored in the database 110 in a state where a data number is assigned, accessed through the assigned data number, or a problem paper output option can be set.

The problem output unit 152 accesses the image data stored in the database 110, reconstructs the image problem based on the data number assigned to the material, and outputs it to the problem paper 10 through the output device. For example, for image data of data type P in the data number, image data of the same output page are collected, arranged according to the output sequence number, and when the value of barcode printing is T (True), it is associated with the image data. Barcodes containing address values of related data are arranged at the top and bottom of the image problem. If the problem type of data number is a short answer question, a space is created for the learner to enter a correct answer. In this case, the problem paper 10 may be in the form of a paper medium printed by a printer, or may be in the form of an electronic document usable in an information providing terminal. When the questionnaire 10 is provided in an electronic form, the user who receives the questionnaire 10 solves the image data printed on the questionnaire 10 and uses the input device 40 to solve the answer to the information providing terminal 20. You can enter The answer can be recognized by input from a touch screen, a keyboard or a remote controller, or in the case of a multiple-choice problem, by using a device such as a touch screen, a mouse, a trackpad, or the like. The method of assigning a coordinate value to the view of the image data is as described with reference to FIG. 4. If the problem paper 10 is a paper printed matter, the user can solve the problem with a writing instrument. In this case, the answer can be recognized using an optical mark reader (OMR) or a scanning mark reader (SMR) method.

In order to use the SMR method, one-dimensional barcodes or two-dimensional barcodes should be printed on the corresponding pages of the questionnaire, and the coordinate values for the example of the multiple-choice problem should be calculated using this as a reference point. User-written answers can be re-entered into the scanner, which also includes a network-enabled copier. Based on the one-dimensional barcode or the two-dimensional barcode printed in the user-created answer, the average value of brightness for the viewing area is calculated. At this time, the user checks the answer using the darkest point, the smallest brightness value, that is, the darkest part by recognizing the answer to the answer can be recognized.

The problem answer processing unit 154 recognizes the solution to the solution, and provides the solution to the problem solution scoring unit 156 together with the user information input to the input device.
