[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an image processing method, and more particularly, to an apparatus and method suitable for application to journal shipping processing such as answer sheets having a fixed form and document classification.
[0002]
[Prior art]
In various mock tests for elementary and junior and senior high school students and students, the test taker selects a mark sheet in the answer column and performs a mark sheet type test that reads this with an OMR (optical mark reader). However, with this simple alternative method, scoring can be automated, but it may happen that the answer is correct by chance, or the mark may be mispainted, and the answerer does not write the answer directly. For this reason, there is a problem that it is difficult to accurately determine the examinee's knowledge and ability with a simple mark sheet.
[0003]
For this purpose, the answerer has recently entered the answer by hand on the answer sheet, and the grader selects the correct / incorrect answer, or the scoring result, selects the appropriate location, and marks (marks) In addition, in the case of incorrect answers on the answer sheet, by correcting what is wrong, etc., at the time of scoring, the scoring field (mark sheet method) of the answer sheet is read by OMR to automate scoring work A test method (OMR scoring method) has been adopted.
[0004]
FIG. 1 schematically shows an answer sheet of the OMR scoring system. Referring to FIG. 1, in this mathematical answer sheet, the answerer writes the answer by hand by hand for each question, and the grader marks the score result (correct or incorrect in FIG. 1) beside the question. To mark. At the time of scoring, the answer sheet is read into the OMR to determine whether the answer is correct or not, and the score of the answerer is automatically derived from the score assigned in advance to the question and its correct / incorrect result.
[0005]
[Problems to be solved by the invention]
However, the above prior art has the following problems.
[0006]
In a mock exam, etc., the scored answer sheet will be sent back to the respondent's address along with a summary result list (average score, deviation value, ranking of outstanding results, analysis, etc.) and advertising notification information such as the next exam schedule. The In this case, the mock test organizer will send it to the respondent by mail or courier. For example, a large number of answer sheets for each test subject such as English, mathematics, Japanese language, society, science, etc. are usually sorted manually for each answerer and sealed.
[0007]
At that time, when a large number of examinees participate in the mock test, the sorting work requires a large number of work steps, resulting in an increase in cost and the work itself is inefficient.
[0008]
Furthermore, until now, the answer sheet has been returned to the respondent as it is (that is, as the original sheet). If there are three or five test subjects, it is difficult to reduce the cost of mailing. It is. In particular, the answer sheet is made of durable paper so that it will not be damaged even if it is erased several times with an eraser, and thin paper cannot be used. This prevents mail costs from being reduced.
[0009]
Therefore, the present invention has been made in view of the above problems, and its purpose is to eliminate the need to rely on manual work for answer sheet distribution work, achieve labor saving and efficiency, and return An object of the present invention is to provide an apparatus and a method for reducing the cost.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the image processing apparatus of the present invention reads, as image data, a sheet in which the determination criterion result of the information is set as a mark (mark) in the information column, and is given a predetermined reference mark. The required information column is extracted as partial image data, the extracted partial image data is automatically edited on an image, and the extracted required information is printed on a sheet.
[0011]
Further, in the image processing apparatus of the present invention, means for reading a graded answer sheet as image data in which the grade of the answer to the question is marked by marking a field provided corresponding to the answer field by the grader And a means for extracting an answer column for a question in which the mark indicates an incorrect answer from the read image data, and the extracted partial image data for each question is preferably stored on a sheet of paper on the image data. Means for automatically editing and arranging, and means for outputting the edited image data.
[0012]
According to the image processing method of the present invention, a graded answer sheet in which the grade of the answer to the question is marked by marking a field provided corresponding to the answer field by the grader is input as image data, and the input The answer column of the question in which the mark indicates an incorrect answer is extracted from the image data, and the partial image data extracted for each question is automatically edited and arranged on the image data so that it preferably fits on one sheet, The edited image data is printed out.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below. In a preferred embodiment of the image processing apparatus according to the present invention, an answer sheet (see FIG. 1) is provided in which the grade of the answer to the question is marked by a marker in a column provided corresponding to the answer column. The means for reading the entire graded answer sheet as image data (101 in FIG. 3 ) and the means for extracting the answer column for the question in which the mark indicates an incorrect answer from the read image data (102 in FIG. 3 ) And the means (103 in FIG. 3 ) for automatically editing and arranging the extracted partial image data for each problem so that the extracted partial image data preferably fits on one sheet of paper on the image data, and outputting the edited image data Means (104 in FIG. 3 ).
[0014]
In a preferred embodiment of the present invention, the image data editing / arranging means answers the partial image data extracted for the answer sheets of a plurality of subjects based on the answerer's personal information (see FIG. 1) entered on the answer sheet. The data is sorted for each person and pasted to the image data corresponding to one sheet, and the answer sheet extraction results of a plurality of subjects are preferably sorted on one sheet for each answerer and printed out by the image data output means.
[0015]
In this case, the personal information of the answerer on the answer sheet and the answerer address information stored in advance in the database of the host computer on the side of the mock test organizer are searched, and the address of the printed return sheet is automatically sent to the envelope. It is configured to automatically enclose the return paper that is printed and printed out in an envelope.
[0016]
That is, an answer sheet (201 in FIG. 2 ) that has been graded for multiple subjects (marked as correct / incorrect for the answer to the question) is displayed on the image processing apparatus (200 in FIG. 2 ) with the configuration shown in FIG. Only the answer and answer column for reading is extracted, and a plurality of subjects are preferably printed on one sheet (202 in FIG. 2 ), and the automatic enclosing device (in FIG. 2) is received in response to the output of this image processing device. 210) is activated, and the answerer personal information on the answer sheet and the answerer address information stored in advance in the database (not shown) of the host computer on the side of the mock test are searched, and the return sheet printed out Are automatically printed on a sealed letter, and the printed paper for return is automatically enclosed in the sealed letter. It should be noted that it is not always necessary for the destination printout and the sealing process to operate in conjunction with the output of the image processing apparatus as long as the process is after the erroneous answer column extraction output by the image processing apparatus.
[0017]
That is, the image data, which is the output of the image processing device, which is a composite of the answer column of the incorrect answer, is temporarily stored in the file device by compression processing, etc. You may make it perform.
[0018]
In the embodiment of the present invention, the image processing apparatus can perform scoring result collection processing. Depending on the scale of the number of examinees, scoring and summarization processing including a large amount of calculation processing such as sorting processing, Statistical processing or the like may be performed on the host computer connected to the image processing apparatus via a network.
[0020]
Further, in the present invention, the image reading means (101 in FIG. 2) and the partial image extracting means (102 in FIG. 2) for extracting the answer column of the incorrect answer are not necessarily integrated with the apparatus. Of course, the image data extraction means (102 in FIG. 2) may be configured to input an image data file that has already been read as image data by another apparatus via a recording medium or a network.
[0021]
In the present invention, the answer sheet is not limited to the OMR method, but can also be applied to a mark sheet type answer sheet in which an answerer directly selects a mark for a question. In this case, whether the answer is correct or not is determined from the position of the mark, and only the answer column for the incorrect answer is extracted as partial image data. That is, according to the present invention, in a preferred embodiment, an answer sheet of a mark sheet method in which an answerer directly selects a mark for a question is read as image data, and an answer column for a question that is an erroneous answer is read from the read image data. Means for extracting partial image data for each problem, means for automatically editing and arranging at least the partial image data extracted for each problem on the image data, preferably on one sheet, and the edited The image data may be automatically sorted for each answerer based on the answerer information entered on the answer sheet, and printed out. Furthermore, the present invention can be similarly applied to an answer sheet (see FIG. 4) in which the mark sheet method and the OMR method are mixed.
[0022]
【Example】
Examples of the present invention will be described below. Hereinafter, an embodiment in which the present invention is applied to an answer sheet sorting and returning system implemented on the side of an organizer such as a mock test will be described.
[0023]
In this embodiment, the premise is that in a mock test or the like, the answerer answered the answer sheet on the answer sheet, and the grader painted the mark provided at the position corresponding to the answer column, so that the correct or incorrect score Is set (see FIG. 1).
[0024]
When the answerer applies for the mock test, personal information such as name and address (destination) is registered in the database of the information processing apparatus on the sponsoring side of the mock test or the like, and ID information is assigned if new. The answerer enters the answerer's identification information, that is, the name or pre-registered ID information in a predetermined field of the answer sheet at the time of performing the test, and the information processing apparatus that has input the ID information includes an answer sheet, Association (association) with an answerer can be performed.
[0025]
Referring to FIG. 2, in this embodiment, in the image reading means 101, the entire area of the scored answer sheet is read by the image reading device and converted into image data. From this image data, a mark sheet corresponding to the answer column Based on the information in the column, correct / incorrect or the like is determined. If the answer is not correct, only the answer column entered by the answerer in the answer column is extracted by the partial image data extracting unit 102, and the image data editing / arranging unit 103 The partial image data in the answer column cut out by the partial image data extraction means 102 is automatically synthesized and edited for each answerer, and printed out on one sheet via the image data output means 104. Then, the answer sheet is returned with an edited form in which only the wrong answer column is extracted. As the image reading unit 101, a high-speed image scanner or the like is used.
[0026]
In the present embodiment, preferably, the answer data of the multiple subjects taken by the respondent is collected image data obtained by extracting the answers in the answer column of the wrong answer as an image, and is classified into subjects and fits on one sheet. Paste and edit as follows. In this case, the partial image data cut out for each subject is temporarily accumulated and held in a predetermined storage device or storage area.
[0027]
As for the answer sheet of the test, the position information and the shape / dimension information of the answer column of each question can be acquired when the answer sheet is created.
[0028]
In this embodiment, the extracted incorrect answer columns are compiled and edited for each test subject from the positional information, shape information, and output target paper size information, and preferably fit on a single sheet. The layout is automatically edited.
[0029]
Also, in this embodiment, the mark sheet type scoring field for the answer field of each question in each subject is not read by OMR, but on the image data read based on the position information in the answer sheet of the mark sheet. A process for determining whether a mark is added is performed. As described above, in this embodiment, since the scoring result is determined on the image data instead of reading the mark sheet with OMR, the processing speed is improved and the layout flexibility of the answer sheet is much higher than that of the conventional method. It will be expanded to.
[0030]
The paper used for the return is a thin paper, and a paper that can be easily folded several times is used, and a size larger than the answer paper is used.
[0031]
In this embodiment, in order to support the processing in this way, the answerer generally needs information on how the answer is incorrect, and for the question that the answerer correctly answers, the answer is the correct answer. Even if it is returned, it is based on the rule of thumb that there is no particular information that the answerer should learn from this correct answer. As in this example, only the wrong answer by the answerer is extracted and returned. However, there is no problem in conducting the test. On the other hand, in the OMR scoring system test, it is considered important that the answerer's handwriting input is important, and it is sufficient if information about what is wrong about the answer handwritten in the answer column is obtained. Yes, even if the handwritten answer column is reduced and returned, the value of the test will not be impaired. In addition, when the answer column regarded as an incorrect answer is completely blank (not filled in), whether or not this is extracted as an incorrect answer is appropriately selected in the system design.
[0032]
Alternatively, an answerer who wants to return all correct answers and incorrect answers as they are may be returned as an option with image data printed on the answer sheet. In this case as well, in this embodiment, the paper to be returned to the answerer may be thinner than the answer paper, and the paper is further reduced in size and printed out, thereby returning the normal answer paper. Even reduce mailing costs.
[0033]
The answer sheet is read as image data, the identification information of the answer sheet is recognized by OCR processing, etc., and the name and destination address information of the answerer already registered in the database etc. is retrieved and used as a return letter. The destination label for each answer sheet is automatically printed, and a known automatic sealing device (210 in FIG. 3) is arranged in the subsequent process of the printer, so that the answer sheet printed on the printer is automatically printed for each answerer. It is also possible to configure a distribution system. This system is effective for labor saving and efficiency improvement of the allocation process in a test with several thousand or tens of thousands of examinees.
[0034]
Next, another embodiment of the present invention will be described. In the above embodiment, the OMR scoring method scored answer sheet is read as image data. However, the OMR scoring method scoring answer sheet only needs to be acquired, and the image processing apparatus can be used. As a device with a function to input image data already read by another host computer equipped via a network or recording medium, extract the wrong answer column from the input image information, and automatically distribute it It may be configured. In other words, in the present embodiment, the image reading device and the device that performs the incorrect answer extraction / editing process for returning the answer sheet may be arranged in a distributed manner. In this case, since the image data input via the network or the recording medium is compressed, it is decompressed and then subjected to mark discrimination and error answer column extraction processing.
[0035]
As still another embodiment of the present invention, a sheet whose determination criterion is set by a mark sheet is read as image data, an information column marked with a predetermined reference mark is extracted, and the extracted partial image data is edited. You may make it print and sort for every applicable person of the paper.
[0036]
【The invention's effect】
As described above, according to the present invention, only the information necessary for the answerer is extracted from the answer sheet, and is preferably printed on one sheet and distributed and returned.・ It is possible to automate the distribution process without impairing the premise of function and customer service, and achieve labor savings. Furthermore, the postage cost for return is particularly reduced, and its practical value is extremely high.
