20230012409
The present disclosure relates to a system, a control method for the system, and a storage medium.
There has recently been an education support system that prints test answer sheets, and scans and marks filled-out answer sheets (see Japanese Patent Application Laid-Open No. 2005-24693).
The use of such a system can automate aggregation of marking results, which has heretofore been manually performed. The time saved can be used for other operations.
An answer sheet can include multiple-choice answer fields and free-form answer fields.
A method discussed in Japanese Patent Application Laid-Open No. 2005-24693 can mark answers and aggregate the marking results.
However, the foregoing system can provide only one free-form answer field and one mark-up field, not a plurality of free-form answer fields.
It has therefore been difficult to recognize marking results of a plurality of free-form questions question by question by scanning such an answer sheet.
According to an aspect of the present disclosure, a system includes a print unit configured to print an answer sheet including a plurality of free-form answer fields and a plurality of marking fields, the plurality of marking fields being configured to mark answers written in the respective plurality of free-form answer fields, a reading unit configured to read the answer sheet printed by the print unit, a marking unit configured to mark the answers based at least on description of the plurality of marking fields included in the answer sheet read by the reading unit, and an aggregation unit configured to aggregate results of marking made by the marking unit.
Further features of various embodiments will become apparent from the following description of exemplary embodiments with reference to the attached drawings.
Some exemplary embodiments of the present disclosure will be described below with reference to the drawings. The following exemplary embodiments are not intended to limit the claims, and not all combinations of features described in the exemplary embodiments are used as the solving means of the present disclosure.
In a first exemplary embodiment, a case where a multifunction peripheral 100 is used as a marking system will be described as an example.
A central processing unit (CPU) 101 is a system control unit, and generally controls the multifunction peripheral 100.
The CPU 101 reads control programs stored in a read-only memory (ROM) 102 and runs the programs. The ROM 102 includes a flash memory, such as an embedded MultiMediaCard (eMMC), and is intended to store the control programs for the CPU 101. The ROM 102 also stores image data.
A dynamic random access memory (DRAM) 103 is intended to store program control variables. The DRAM 103 is a volatile memory capable of temporarily storing image data to be processed.
An operation unit 104 functions as a user interface unit. The operation unit 104 includes a touch panel including a liquid crystal display unit to which a touch panel sheet for accepting user operations is attached. The operation unit 104 displays various screens and information on the touch panel. The operation unit 104 also includes hardware keys, such as a start key and a reset key.
A scanner 105 is a device for reading image data and converting the image data into binary data. The scanner 105 is used to read documents as a part of an image transmission function.
A printer 106 is a device that performs fixing temperature control to fix image data to a recording sheet, and outputs the recording sheet.
A communication unit 107 is an interface unit between the multifunction peripheral 100 and an external communication network. The communication unit 107 includes a network communication unit that is an interface with a network.
An image processing unit 108 includes an application-specific integrated circuit (ASIC) for performing image processing on input and output image data. Examples of the image processing include resolution conversion, compression and decompression, and rotation.
The foregoing components are connected to one another via a data bus 109.
Next, examples of screens displayed on the multifunction peripheral 100 will be described.
A home screen example 110 in
An application main screen example 111 in
An answer sheet generation and print screen example 112 in
An answer sheet preview screen example 113 in
The marker (teacher) hands out the answer sheets printed by the multifunction peripheral 100 to answerers (students). The marker fills out the first answer sheet with correct answers. The marker hands out the second and subsequent answer sheets to the answerers. After the answerers fill out the answer sheets, the marker collects the answer sheets from the answerers, and marks the answers to the free-form questions. The marker makes the multifunction peripheral 100 read the correct-answer sheet and the answer sheets, with the correct-answer sheet as the first sheet and the answer sheets the second and subsequent sheets.

Answer sheet data 200 illustrated in
A two-dimensional code for identifying answer sheet information about whether the sheet type is a correct-answer sheet or an answer sheet is attached to the answer sheet data 200. An example of the answer sheet information is a generated answer sheet pattern identifier (ID). While a Quick Response (QR) Code® is attached as an example here, two-dimensional codes of other forms (such as Data Matrix and MaxiCode) may be used.
An answer sheet pattern configuration diagram 201, an example 209 of a pattern marker 202, an example 210 of a multiple-choice question configuration diagram, a multiple-choice question choice configuration diagram 211, an example 212 of a free-form question configuration diagram, and a grade area configuration diagram 213 illustrated in
These diagrams and examples illustrate the elements constituting an example of answer sheet data illustrated as the answer sheet data 200. As illustrated in the answer sheet pattern configuration diagram 201, a pattern coordinate system origin Op is set at the top left of the answer sheet data. In such a case, a two-dimensional code for identifying the answer sheet information, called pattern marker 202, is drawn at a position offset by DEF_ID_LM in an X direction and DEF_ID_TM in a Y direction. Multiple-choice questions 203 to 205 and free-form questions 206 to 208 are drawn DEF_PAT_VOFST apart from each other in the Y direction, starting at a position offset by DEF_PAT_LM in the X direction and DEF_PAT_TM in the Y direction.
The pattern marker 202 drawn as described above has a size of DEF_ID_WIDTH in width and DEF_ID_HEIGHT in height as illustrated in the example 209 of the pattern marker 202.
The multiple-choice questions 203 to 205 are configured as in the example 210 of the multiple-choice question configuration diagram, each including an index area indicating a question number, a data area indicating choices to the question, and an answer area (hereinafter, referred to as an ans area) to be filled with an answer. The index area includes an element indicating the question number, drawn within an area of DEF_IA_WIDTH in width and DEF_IA_HEIGHT in height with the top left of the index area as the origin of the coordinate system. The data area is an area of DEF_DA_WIDTH in width and DEF_DA_HEIGHT in height, with the top left of the data area as the origin of the coordinate system. As illustrated in the multiple-choice question choice configuration diagram 211, choice elements having a width of DEF_MARK_WIDTH and a height of DEF_MARK_HEIGHT are drawn in the data area. In the case of the multiple-choice questions 203 to 205, the ans area agrees with the data area.
The free-form questions 206 to 208 are configured as illustrated in the example 212 of the free-form question configuration diagram. Like the multiple-choice questions 203 to 205, the free-form questions 206 to 208 each include an index area indicating the question number and a data area indicating a question answer field. However, unlike the multiple-choice questions 203 to 205, the data area is clearly divided between an ans area including a free-form answer field and a grade area including a mark-up field (an example of a marking field). The ans area is an area having a width of DEF_AA_WIDTH and a height of DEF_AA_HEIGHT with the top left of the data area as the origin of the coordinate system like the data area. A line representing the free-form answer field is drawn at the bottom of the ans area. The grade area includes a grade mark field drawn within an area of DEF_GA_WIDTH in width and DEF_GA_HEIGHT in height, with coordinates offset by DEF_AA_WIDTH in the X direction from the data area coordinate system origin as its coordinate system origin.
The mark-up field is configured as illustrated in the grade area configuration diagram 213. Marking marks having a size of DEF_GD_WIDTH in width and DEF_GD_HEIGHT in height are drawn, starting at the position offset by DEF_GD_LM in the X direction and DEF_GD_TM in the Y direction from the grade coordinate system origin. In the illustrated case, JUDGEMARK_CORRECT indicating a correct answer ∘ and JUDGEMARK_INCORRECT indicating an incorrect answer x are drawn as an example.
An answer sheet pattern database (DB) configuration 300, an example 304 of pattern marker information to be attached to a correct-answer sheet, and an example 305 of pattern marker information to be attached to an answer sheet in
In the present exemplary embodiment, in generating answer sheet data, the pattern configuration illustrated in the answer sheet pattern configuration diagram 201 of
The example 304 of pattern marker information to be attached to a correct-answer sheet and the pattern marker information 305 to be attached to an answer sheet, generated by using the answer sheet pattern data on the element 301 will now be described. The example 304 of pattern marker information to be attached to a correct-answer sheet includes PATTERN_ID_A as patternID data. PATTERN_ID_A serves as a key in obtaining PATTERN_DATA_A indicated by the element 301. The example 304 of pattern marker information also includes PATTERN_REF as patternKind data. PATTERN_REF indicates that the sheet to which this marker is attached is a correct-answer sheet. A generic format, such as JavaScript Object Notation (JSON) format, which is described as an example in the present exemplary embodiment, is applied to the data. The same applies to the example 305 of pattern marker information to be applied to an answer sheet. The only difference is that PATTERN_TEST indicating that the sheet to which this maker is attached is an answer sheet is included as the pattenKind data.
With such a configuration, if a plurality of pieces of answer sheet data 200 is generated by the multifunction peripheral 100, the pattern marker 202 can be decoded to obtain patternID data, and corresponding desired answer sheet pattern data can be obtained using the patternID data. Information to be used for marking and aggregation, such as the numbers and positions of multiple-choice questions and free-form questions in the test, can be obtained from the obtained answer sheet pattern data.
Now, an example 306 of answer sheet pattern data and an example 313 of detailed data on data area information Da about a multiple-choice question in
The example 306 of answer sheet pattern data is an example of answer sheet pattern data when the answer sheet pattern configuration diagram 201 illustrated in
The example 306 of answer sheet pattern data is a specific example of the answer sheet pattern data PATTERN_DATA_A stored in the element 301 of the answer sheet pattern DB configuration 300. Here, the multiple-choice questions 203 to 205 and the free-form questions 206 to 208 in the answer sheet pattern configuration diagram 201 illustrated in
As described above, the element 307 represents the multiple-choice question 203, where an index number of 1 is assigned and the question format is QUESTION_MARK indicating a multiple-choice question. The index area information Ia includes DEF_PAT_LM as the X coordinate of the start position (hereinafter, may be referred to as a start position X), DEF_PAT_TM as the Y coordinate of the start position (hereinafter, may be referred to as a start position Y), DEF_IA_WIDTH as the width, and DEF_IA_HEIGHT as the height. The data area information Da includes DEF_PAT_LM+DEF_IA_WIDTH as the X coordinate of the start position, DEF_PAT_TM as the Y coordinate, DEF_DA_WIDTH as the width, and DEF_DA_HEIGHT as the height. Moreover, MARK_DETAIL_1 to be described below is included as detailed data on the data area information Da.
The elements 308 and 309 represent the multiple-choice questions 204 and 205, respectively, and have basically similar content to that of the element 307.
Differences of the element 308 from the element 307 will be described. The multiple-choice question 204 is assigned an index number of 2 and located below the multiple-choice question 203. The Y coordinates of the start positions in the index area information Ia and the data area information Da are thus set to DEF_PAT_TM+DEF_IA_HEIGHT+DEF_PAT_VOFST, i.e., where the height of the multiple-choice question 203 and a distance offset are added. MARK_DETAIL_2 is included as detailed data on the data area information Da.
Differences of the element 309 from the element 307 will be described. The multiple-choice question 205 is assigned an index number of 3 and located below the multiple-choice questions 203 and 204. The Y coordinates of the start positions in the index area information Ia and the data area information Da are thus set to which the heights of the multiple-choice questions 203 and 204 and the distance offsets are added.
Specifically, the Y coordinates are set to DEF_PAT_TM+DEF_IA_HEIGHT*2+DEF_PAT_VOFST*2. MARK_DETAIL_3 is included as detailed data on the data area information Da.
The element 310 represents the free-form question 206. The assigned index number is 4, and the question format is QUESTION_WRITE indicating a free-form question. The X coordinate of the start position in the index area information Ia is set to DEF_PAT_LM. Since the free-form question 206 is located below the multiple-choice questions 203 to 205, the Y coordinate is set to DEF_PAT_TM+DEF_IA_HEIGHT*3+DEF_PAT_VOFST*3, i.e., where the heights of the multiple-choice questions 203 to 205 and the distance offsets are added. The X coordinate of the start position in the data area information Da is set to DEF_PAT_LM+DEF_IA_WIDTH. Like the index area information Ia, since the free-form question 206 is located below the multiple-choice questions 203 to 205, the Y coordinate in the data area information Da is set to which the heights of the multiple-choice questions 203 to 205 and the distance offsets are added. Specifically, the Y coordinate is set to DEF_PAT_TM+DEF_IA_HEIGHT*3+DEF_PAT_VOFST*3. The width is DEF_DA_WIDTH, and the height is DEF_DA_HEIGHT. Moreover, WRITE_DETAIL_1 to be described below is included as detailed data on the data area information Da.
The elements 311 and 312 represent the free-form questions 207 and 208, respectively, and have basically similar content to that of the element 310.
Differences of the element 311 from the element 310 will be described. The free-form question 207 is assigned an index number of 5 and located below the multiple-choice questions 203 to 205 and the free-form question 206. The Y coordinates of the start positions in the index area information Ia and the data area information Da are thus set to DEF_PAT_TM+DEF_IA_HEIGHT*4+DEF_PAT_VOFST*4. WRITE_DETAIL_2 is included as detailed data on the data area information Da.
Differences of the element 312 from the element 310 will be described. The free-form question 208 is assigned an index number of 6 and located below the multiple-choice questions 203 to 205 and the free-form questions 206 and 207. The Y coordinates of the start positions in the index area information Ia and the data area information Da are thus set to DEF_PAT_TM+DEF_IA_HEIGHT*5+DEF_PAT_VOFST*5. WRITE_DETAIL_3 is included as detailed data on the data area information Da.
The example 313 of the detailed data on the data area information Da about a multiple-choice question is a specific example of MARK_DETAIL_1 to MARK_DETAIL_3 included in the foregoing elements 307 to 309. The data area of a multiple-choice question includes only the ans area. The X and Y coordinates of the start position in ans area information Aa, expressed by relative coordinates with respect to the data area coordinate system origin, are hence 0. The width is DEF_DA_WIDTH, and the height is DEF_DA_HEIGHT.
The example 314 of the detailed data on the data area information Da about a free-form question is a specific example of WRITE_DETAIL_1 to WRITE_DETAIL_3 included in the foregoing elements 310 to 312. The data area of a free-form question includes the ans area and the grade area. As with the multiple-choice questions, the coordinates of the areas are expressed by relative coordinates with respect to the data area coordinate system origin. The X and Y coordinates of the start position in the ans area information Aa are hence 0. The width is DEF_AA_WIDTH, and the height is DEF_AA_HEIGHT. The X coordinate of the start position in the grade area information Ga is DEF_AA_WIDTH, i.e., shifted as much as the ans area in the X direction. The Y coordinate is 0. The width is DEF_GA_WIDTH, and the height is DEF_GA_HEIGHT. GA_DETAIL_X is included as detailed data on the grade area information Ga.
The example 315 of the detailed data on the grade area information Ga about a free-form question is a specific example of the foregoing GA_DETAIL_X. Elements 316 and 317 indicate information about areas where JUDGEMARK_CORRECT and JUDGEMARK_INCORRECT are drawn in the grade area configuration diagram 213, respectively.
The element 316 includes JUDGEMARK_CORRECT representing a correct answer ∘ as a marking type. The X and Y coordinates of the start position expressed by relative coordinates with respect to the grade area coordinate system origin are DEF_GD_LM and DEF_GD_TM, respectively. The width is DEF_GD_WIDTH, and the height is DEF_GD_HEIGHT.
The element 317 includes JUDGEMARK_INCORRECT representing an incorrect answer x as the marking type. The X and Y coordinates of the start position expressed by relative coordinates with respect to the grade area coordinate system origin are DEF_GD_LM+DEF_GD_WIDTH and DEF_GD_TM, respectively. The width is DEF_GD_WIDTH, and the height is DEF_GD_HEIGHT.
In the present exemplary embodiment, in marking and aggregating answers, the areas are identified and processed by referring to the index area information Ia and the data area information Da about each question included in the foregoing answer sheet pattern data.

If the read image data is not answer sheet data (NO in step S716), the processing proceeds to step S718.
In step S717, the CPU 101 performs marking processing on the read image data. The processing proceeds to step S718.
In step S718, the CPU 101 checks whether all the pieces of image data have been processed. If all the pieces of image data have been processed (YES in step S718), the processing of this flowchart ends. If there is image data yet to be processed (NO in step S718), the processing proceeds to step S719.
In step S719, the CPU 101 reads the next piece of image data from the ROM 102 or the DRAM 103. The processing proceeds to step S716.
In step S720, the CPU 101 obtains an image difference between the answer sheet data and the correct-answer sheet data identified in step S713 (image difference calculation processing). The processing proceeds to step S721. The image difference calculation processing performed here may be typical conventional processing, such as pixel value subtraction.
In step S721, the CPU 101 obtains data area information Da about the first question from the answer sheet pattern data obtained in step S703, and obtains pixels in the data area. The processing proceeds to step S722.
In step S722, the CPU 101 performs marking result obtaining processing on the pixels in the data area. The processing proceeds to step S723.
In step S723, the CPU 101 checks whether all the questions have been processed. If all the questions have been processed (YES in step S723), the processing of this flowchart ends. If there is a question yet to be processed (NO in step S723), the processing proceeds to step S724.
In step S724, the CPU 101 obtains data area information Da about the next question, and obtains pixels in the corresponding data area. The processing proceeds to step S722.
In step S725, the CPU 101 checks whether the question format is a multiple-choice question. If the question format is a multiple-choice question (YES in step S725), the processing proceeds to step S726. If the question format is not a multiple-choice question (NO in step S725), the processing proceeds to step S730.
In step S726, the CPU 101 calculates an average value Mean of the pixel values in the data area. The processing proceeds to step S727. Here, the average value Mean can be calculated by using a typical conventional method, such as dividing an integrated pixel value by the area of the target area.
In step S727, the CPU 101 checks whether the average value Mean of the pixel values calculated in step S726 is greater than or equal to a predetermined threshold. If the average value Mean is greater than or equal to the threshold (YES in step S727), the processing proceeds to step S728. If the average value Mean is less than the threshold (NO in step S727), the processing proceeds to step S729.
If the choices on the correct-answer sheet and the answer sheet are filled exactly the same way, the image difference in the data area is zero. The average value Mean of the pixel values thus approaches zero, even with noise taken into account. By contrast, if different choices are filled, the average value Mean of the pixels is relatively large since the pixels of the filled choices of both the correct answer and incorrect answer remain in the obtained image difference. Whether the target choice is correct or incorrect can thus be determined by comparing the average value Mean with the threshold in step S727.
In step S728, the CPU 101 determines that the answer to the target question is incorrect. The processing proceeds to step S735.
In step S729, the CPU 101 determines that the answer to the target question is correct. The processing proceeds to step S735.
In step S730, the CPU 101 obtains pixels in the grade area. The processing proceeds to step S731.
In step S731, the CPU 101 obtains average pixel values of the respective marking types in the grade area. The processing proceeds to step S732. As with a multiple-choice question in step S727, if the choices are filled exactly the same way, the image difference is zero. If the choices are filled differently, the pixels of the filled portions remain as an image difference. In the grade area of a free-form question, the pixels of a filled portion always remain as an image difference. The marking type corresponding to the area of the greater average pixel value can thus be determined to be the marking result filled by the user (marker).
In step S732, the CPU 101 checks whether the marking type corresponding to the area of the greater average pixel value is x. If the marking type is x (YES in step S732), the processing proceeds to step S733. If the marking type is not x (NO in step S732), the processing proceeds to step S734.
In step S733, the CPU 101 determines that the answer to the target question is incorrect. The processing proceeds to step S735.
In step S734, the CPU 101 determines that the answer to the target question is correct. The processing proceeds to step S735.
In step S735, the CPU 101 obtains the score on the target question (score obtaining processing). The processing of this flowchart ends.
In step S736, the CPU 101 checks whether the answer to the question is determined to be correct. If the answer is determined to be correct (YES in step S736), the processing proceeds to step S737. If the answer is not determined to be correct (NO in step S736), the processing proceeds to step S738.
In step S737, the CPU 101 determines that the score is one point. The processing of this flowchart ends.
In step S738, the CPU 101 determines that the score is zero points. The processing of this flowchart ends.
As described above, the multifunction peripheral 100 can singly provide a system for generating and printing answer sheets and performing marking and aggregation.
In the first exemplary embodiment, the system for generating and printing answer sheets and performing marking and aggregation is described to be completed by the multifunction peripheral 100 alone. In a second exemplary embodiment, a system that performs a series of processes in cooperation with an external general education support system will be described in terms of differences in processing from the first exemplary embodiment. The second exemplary embodiment is different from the first exemplary embodiment in the source from which student-filled answer sheet data is obtained and the timing of drawing of grade areas on the answer sheet data. While this system cooperates with the external education support system, processing related to a login to and data acquisition from the education support system is irrelevant to the description of the present exemplary embodiment. The login and data acquisition therefore shall be performed by using typical conventional techniques, and the processing will not be mentioned in the present exemplary embodiment.

In step S901, the CPU 101 obtains the first element of answer sheet pattern data. The processing proceeds to step S902.
In step S902, the CPU 101 refers to the element obtained in step S901, and draws the index number in the index area. The processing proceeds to step S903.
In step S903, the CPU 101 checks whether the question format of the element to be drawn is a multiple-choice question. If the question format is a multiple-choice question (YES in step S903), the processing proceeds to step S904. If the question format is not a multiple-choice question (NO in step S903), the processing proceeds to step S905.
In step S904, the CPU 101 draws choices in the ans area. The processing proceeds to step S906.
In step S905, the CPU 101 draws a line for a free-form question in the ans area. The processing proceeds to step S906.
In step S906, the CPU 101 checks whether the drawing processing has been completed of all the elements. If all the elements have been drawn (YES in step S906), the processing of this flowchart ends. If all the elements have not been drawn (NO in step S906), the processing proceeds to step S907.
In step S907, the CPU 101 obtains the next element from the answer sheet pattern data. The processing proceeds to step S902.
It can be seen that, unlike the first exemplary embodiment, the grade area including a mark-up field is not drawn at the timing when the answer sheet data is generated and printed.
In step S908, the CPU 101 logs in to the external education system 801, obtains students' answers (hereinafter, referred to as answer data), and stores the obtained answer data in the ROM 102 or the DRAM 103. The processing proceeds to step S909. There are various methods for logging in to the external education system 801 and obtaining data. Since the methods here do not need to be limited, typical conventional methods are used.
In step S909, the CPU 101 combines the answer data obtained in step S908 with mark-up fields, and makes the printer 106 print the resulting data (mark-up field composite print processing). The processing of this flowchart ends.
This enables the multifunction peripheral 100 to perform marking and aggregation processing as in the first exemplary embodiment even if there are free-form questions.
In step S910, the CPU 101 reads image data that is a piece of answer data from the ROM 102 or the DRAM 103. The processing proceeds to step S911.
In step S911, the CPU 101 obtains pixels in the marker area from the obtained image data. The processing proceeds to step S912.
In step S912, the CPU 101 performs two-dimensional code decoding processing on the obtained pixels in the marker area to obtain an answer sheet pattern ID. The processing proceeds to step S913.
In step S913, the CPU 101 obtains answer sheet pattern data using the obtained answer sheet pattern ID. The processing proceeds to step S914.
In step S914, the CPU 101 performs mark-up field combining processing on the image data using the obtained answer sheet pattern data. The processing proceeds to step S915.
In step S915, the CPU 101 makes the printer 106 print the image data with which the mark-up fields are combined. The processing proceeds to step S916.
In step S916, the CPU 101 checks whether all the pieces of image data have been processed.
If all the pieces of image data have been processed (YES in step S916), the processing of this flowchart ends. If there is image data yet to be processed (NO in step S916), the processing proceeds to step S917.
In step S917, the CPU 101 reads the next piece of image data from the ROM 102 or the DRAM 103. The processing proceeds to step S914.
In step S918, the CPU 101 obtains the first element of the answer sheet pattern data. The processing proceeds to step S919.
In step S919, the CPU 101 checks whether the question format of the processing target is a free-form question. If the question format is a free-form question (YES in step S919), the processing proceeds to step S920. If the question format is not a free-form question (NO in step S919), the processing proceeds to step S921 since a mark-up field does not need to be combined.
In step S920, the CPU 101 draws a mark-up field in the grade area. The processing proceeds to step S921.
In step S921, the CPU 101 checks whether the mark-up field drawing processing has been performed on all the elements. If the mark-up field drawing processing has been performed on all the elements (YES in step S921), the processing of this flowchart ends. If there is an element yet to be processed (NO in step S921), the processing proceeds to step S922.
In step S922, the CPU 101 obtains the next element from the answer sheet pattern data. The processing proceeds to step S919.
By the foregoing processing, all the free-form questions in the answer image data can be combined with mark-up fields.
As described above, if the multifunction peripheral 100 and the external education system 801 are cooperating, answer sheet data is generated without combining mark-up fields. The image data obtained from the education system 801 is then combined with mark-up fields and printed. A system that generates and prints answer sheets and performs marking and aggregation in a similar manner to the first exemplary embodiment can thereby be provided.
In the first and second exemplary embodiments, the system is described to allocate the same points to all the multiple-choice questions and free-form questions. However, free-form questions are often given different points depending on their difficulty level. A third exemplary embodiment thus deals with a system where, unlike the first and second exemplary embodiments, different points are allocated question by question. Only differences of the third exemplary embodiment from the first and second exemplary embodiments will be described.
An answer sheet generation and print screen 1000 illustrates a screen for generating and printing answer sheets according to the third exemplary embodiment. Unlike the answer sheet generation and print screen example 112 displayed in the first and second exemplary embodiments, an other-settings button for marking point settings is added to the answer sheet generation and print screen 1000.
An other-settings screen 1001 is a screen displayed if the other-settings button displayed on the answer sheet generation and print screen 1000 is pressed. Since the third exemplary embodiment is intended to change points question by question, a menu to change points question by question is displayed.
A change points question by question screen 1002 is a screen displayed if the “change points question by question button” displayed on the other-settings screen 1001 is pressed. The change points question by question screen 1002 displays two items, one related to a base point and the other for setting points question by question. If the “base point” button is pressed to set points, the points of all the questions are changed to the same value. If the “set points question by question” button is pressed and the point of a specific question is set, the point of that question is changed.
A point setting screen 1003 is a screen displayed when the “set points question by question” button is pressed on the change points question by question screen 1002. The point setting screen 1003 is similar to the answer sheet preview screen example 113 in appearance, and a specific question can be selected by tapping on the operation unit 104.
A point input screen 1004 is a screen displayed if the “base point” button is pressed on the change points question by question screen 1002 or if a specific question is selected on the point setting screen 1003. A change can be applied by inputting points using the numerical keypad on the point input screen 1004 and pressing an “apply” button.
Such a configuration enables both uniform and question-by-question changes of point allocation.
In step S1201, the CPU 101 checks whether the answer to the question is determined to be correct. If the answer is determined to be correct (YES in step S1201), the processing proceeds to step S1202. If the answer is not determined to be correct (NO in step S1201), the processing proceeds to step S1205.
In step S1202, the CPU 101 checks the answer sheet pattern data for point information. If there is point information (YES in step S1202), the processing proceeds to step S1203. If there is no point information (NO in step S1202), the processing proceeds to step S1204.
In step S1203, the CPU 101 obtains points from the point information about this element of the answer sheet pattern data. The processing of this flowchart ends.
In step S1204, the CPU 101 determines that the score is one point. The processing of this flowchart ends.
In step S1205, the CPU 101 determines that the score is zero points. The processing of this flowchart ends.
As described above, a system can be provided that generates and prints answer sheets with different points allocated question by question and performs marking and aggregation.
In the third exemplary embodiment, a system for handling the case where different points are allocated question by question has been described.
However, as a method for point allocation, point information may be obtained from answer sheets instead of providing the answer sheet pattern data with the point information. In a fourth exemplary embodiment, a system that obtains point information from answer sheets will be described. Again, differences between the fourth exemplary embodiment and the foregoing exemplary embodiments will be described.
A change points question by question screen 1300 in the point setting method for inputting points from the operation screen is a change points question by question screen displayed in an initial state in the fourth exemplary embodiment. The initial value in the point setting method is set at “input points from the operation screen”, which corresponds to the case discussed in the third exemplary embodiment. The change points question by question screen 1300 displays the following three items: an item to set a base point and an item to set points question by question like the change points question by question screen 1002 illustrated in
A point setting method screen 1301 is a screen displayed to select a method for obtaining points. Inputting points on the operation screen refers to the point setting method according to the third exemplary embodiment. Adding a point mark digit field to the answer sheet and adding as many point mark fields as the number of points to the answer sheet refer to point setting methods proposed in this fourth exemplary embodiment.
A change points question by question screen 1302 in the point setting method for adding a point mark digit field to the answer sheet illustrates a screen displayed if the choice to add a point mark digit field to the answer sheet is selected on the point setting method screen 1301. In the case of this setting method, there is no item to be input on the operation screen since point information is obtained from point mark digit fields added to the answer sheet. Items such as a basic point are therefore not displayed.
A change points question by question screen 1303 in the point setting method for adding as many point mark fields as the number of points to the answer sheet illustrates a screen displayed if the choice to add as many point mark fields as the number of points to the answer sheet is selected on the point setting method screen 1301. In such a case, there is a point mark field setting item to set how many points to add point mark fields.
A point mark field setting screen 1304 is a screen for setting how many points to add point mark fields if as many point mark fields as the number of points are to be added to the answer sheet. The lowest points, the highest points, and a pitch of how many points to generate mark fields at can be specified.
A mark-up field 1305 in the case where a point mark digit field is added is an example of the mark-up field to be drawn in the grade area of the answer sheet if the choice to add a point mark digit field to the answer sheet is selected. A mark digit field is added to the conventional mark fields ∘ and x. In such a case, the points to the question can be determined by filling in a digit of 0 to 9.
A mark-up field 1306 in the case where as many point mark fields as the number of points are added is an example of the mark-up field drawn in the grade field of the answer sheet if the choice to add as many point mark fields as the number of points to the answer sheet is selected. As many point-allocated ∘ mark fields as the number of points set on the point mark field setting screen 1304 are added to the conventional x mark field. Here, the points to a correct answer to the question can be determined by filling out an appropriate point-allocated ∘ mark field.
Now, an example 1404 of detailed data on data area information Da, an example 1401 of detailed data on grade area information Ga, and a grade area configuration diagram 1405 in
The example 1400 of detailed data on the data area information Da of the answer sheet pattern data includes basically the same information as that of the example 314 of detailed data on the data area information Da about a free-form question in
The example 1401 of detailed data on the grade area information Ga about a free-form question includes basically the same information as that of the example 315 of detailed data on the grade area information Ga in
Specifically, like the element 316, an element 1402 contains information about a JUDGEMARK_CORRECT area indicating a correct answer ∘. Like the element 317, an element 1403 contains information about a JUDGEMARK_INCORRECT area indicating an incorrect answer x. The difference is in an element 1404, which contains information about a DIGITMARK_CORRECT area that is a digit mark area to include point information about a correct answer ∘. In obtaining points to the correct answer during marking, the CPU 101 can obtain the points by performing image processing on the DIGITMARK_CORRECT area defined by the element 1404.
The grade area configuration diagram 1405 has basically the same configuration as that of the grade area configuration diagram 213 in
An example 1406 of detailed data on data area information Da, an example 1407 of detailed data on grade area information Ga, and a grade area configuration diagram 1414 in

Specifically, like the element 316, elements 1408 to 1412 contain information about a JUDGEMARK_CORRECT area indicating a correct answer ∘. Differences are in the X coordinate of the start position due to the provision of as many JUDGEMARK_CORRECT areas as the number of points, and in that an item related to point information is added. Since the point information is set with respect to each of the elements 1408 to 1412, the CPU 101 can identify the score by obtaining the point information about the element corresponding to the selected area.
Like the element 317, an element 1413 contains information about a JUDGEMARK_INCORRECT area indicating an incorrect answer x. Again, differences are in the X coordinate of the start position and in that point information is added. Since the answer is incorrect, zero points are set here.
The grade area configuration diagram 1414 has basically the same configuration as that of the grade area configuration diagram 213 in
In step S1501, the CPU 101 checks whether the answer to the target question is determined to be correct. If the answer is determined to be correct (YES in step S1501), the processing proceeds to step S1502. If the answer is not determined to be correct (NO in step S1501), the processing proceeds to step S1504.
In step S1502, the CPU 101 obtains pixels in the DIGITMARK_CORRECT area. The processing proceeds to step S1503.
In step S1503, the CPU 101 performs pattern matching on the obtained pixels to obtain the score. The processing of this flowchart ends. The pattern matching performed in this processing may be typical conventional matching processing. Examples include using the sum of squares of differences in pixel value, and using the sum of absolute values of differences in pixel value.
In step S1504, the CPU 101 determines that the score is zero points. The processing of this flowchart ends.
In step S1505, the CPU 101 checks whether the answer to the target question is determined to be correct. If the answer is determined to be correct (YES in step S1505), the processing proceeds to step S1506. If the answer is not determined to be correct (NO in step S1505), the processing proceeds to step S1508.
In step S1506, the CPU 101 obtains the average pixel values of the respective JUDGEMARK_CORRECT areas. The processing proceeds to step S1507. The average pixel value obtaining processing performed here may use a typical conventional means, such as dividing an integrated pixel value by the area.
In step S1507, the CPU 101 obtains point information about the area of the highest average pixel value from the detailed data on the grade area information Ga. The processing of this flowchart ends.
In step S1508, the CPU 101 determines that the score is zero points. The processing of this flowchart ends.
As described above, a system can be provided that generates and prints answer sheets from which, if different points are allocated question by question, the points can be identified by obtaining point mark information drawn on the answer sheets aside from inputting the points on the operation screen, and performs marking and aggregation.
In the first to fourth exemplary embodiments, a system has been described that handles the case where possible marking types are ∘ representing a correct answer and x representing an incorrect answer. However, in the case of free-form questions, a marking type Δ representing a partially correct answer can be used to give partial marks. In a fifth exemplary embodiment, a system capable of handling ∘ representing a correct answer, x representing an incorrect answer, and Δ representing a partially correct answer will be described. Again, differences between the fifth exemplary embodiment and the foregoing exemplary embodiments will be described.
An example 1600 of detailed data on data area information Da, an example 1601 of detailed data on grade area information Ga, and a grade area configuration diagram 1607 in
The example 1600 of detailed data on the data area information Da of the answer sheet pattern data includes basically the same information as that of the example 1400 of detailed data on the data area information Da in
Elements 1602 to 1606 contain basically the same information as that of the elements 1402 to 1404 in
Specifically, like the element 1402, the element 1602 contains information about a JUDGEMARK_CORRECT area indicating a correct answer ∘. Like the element 1403, the element 1603 contains information about a JUDGEMARK_INCORRECT area indicating an incorrect answer x. Like the element 1404, the element 1605 contains information about a DIGITMARK_CORRECT area that is a digit mark area to include point information about a correct answer ∘.
A difference is that the elements 1604 and 1606 are added.
The element 1604 contains information about a JUDGEMARK_PARTIAL area indicating a partially correct answer Δ. The JUDGEMARK_PARTIAL area is defined to be drawn next to the JUDGEMARK_INCORRECT area.
The element 1606 contains information about a DIGITMARK_PARTIAL area that is a digit mark area to include point information about a partially correct answer Δ. The DIGITMARK_PARTIAL area is defined to be drawn directly below the JUDGEMARK_PARTIAL area. In obtaining points to a partially correct answer during marking, a CPU 101 can obtain the points by performing image processing on the DIGITMARK_PARTIAL area defined by the element 1606.
The grade area configuration diagram 1607 has basically the same configuration as that of the grade area configuration diagram 1405 in
An example 1608 of detailed data on data area information Da, an example 1609 of detailed data on grade area information Ga, and a grade area configuration diagram 1616 in
The example 1608 of detailed data on the data area information Da of the answer sheet pattern data includes basically the same information as that of the example 1406 of detailed data on the data area Information Da in
The example 1609 of detailed data on grade area information Ga contains basically the same information as that of the example 1407 of detailed data on the grade area information Ga about a free-form question in
Specifically, like the elements 1408 to 1412, elements 1610 to 1612 contain information about a JUDGEMARK_CORRECT area indicating a correct answer ∘ and points. Like the element 1413, an element 1613 contains information about a JUDGEMARK_INCORRECT area indicating an incorrect answer x.
A difference is in the addition of elements 1614 and 1615 that are information about a JUDGEMARK_PARTIAL area indicating a partially correct answer Δ and points. The element 1614 corresponds to a case where the points is one point. The element 1615 corresponds to a case where the points are two points. There is no partially correct answer element corresponding to three points since the highest points, three, means a correct answer ∘.
The grade area configuration diagram 1616 has basically the same configuration as that of the grade area configuration diagram 1414 in
In step S1701, the CPU 101 checks whether the question format is a multiple-choice question. If the question format is a multiple-choice question (YES in step S1701), the processing proceeds to step S1702. If the question format is not a multiple-choice question (NO in step S1701), the processing proceeds to step S1707.
In step S1702, the CPU 101 calculates an average value Mean of the pixel values in the data area. The processing proceeds to step S1703. Here, the average value Mean is calculated by using a typical conventional means.
In step S1703, the CPU 101 checks whether the average value Mean of the pixel values calculated in step S1702 is greater than or equal to a predetermined threshold. If the average value Mean is greater than or equal to the threshold (YES in step S1703), the processing proceeds to step S1704. If the average value Mean is less than the threshold (NO in step S1703), the processing proceeds to step S1705.
In step S1704, the CPU 101 determines that the answer to the target question is incorrect. The processing proceeds to step S1706.
In step S1705, the CPU 101 determines that the answer to the target question is correct. The processing proceeds to step S1706.
In step S1706, the CPU 101 performs score obtaining processing. The processing of this flowchart ends. Details of the score obtaining processing will be described below with reference to another flowchart.
In step S1707, the CPU 101 obtains pixels in the grade area. The processing proceeds to step S1708.
In step S1708, the CPU 101 obtains the average pixel values of the respective marking types in the grade area. The processing proceeds to step S1709.
In step S1709, the CPU 101 checks whether the marking type of the area of the highest average pixel value is x. If the marking type is x (YES in step S1709), the processing proceeds to step S1710. If the marking type is not x (NO in step S1709), the processing proceeds to step S1711.
In step S1710, the CPU 101 determines that the answer to the target question is incorrect. The processing proceeds to step S1714.
In step S1711, the CPU 101 checks whether the marking type of the area of the highest average pixel value is ∘. If the marking type is ∘ (YES in step S1711), the processing proceeds to step S1712. If the marking type is not ∘ (NO in step S1711), the processing proceeds to step S1713.
In step S1712, the CPU 101 determines that the answer to the target question is correct. The processing proceeds to step S1714.
In step S1713, the CPU 101 determines that the answer to the target question is partially correct. The processing proceeds to step S1714.
In step S1714, the CPU 101 checks whether the grade type is JUDGE_WITH_DIGIT indicating the addition of a digit mark area. If the grade type is JUDGE_WITH_DIGIT indicating the addition of a digit mark area (YES in step S1714), the processing proceeds to step S1716. If the grade type is not JUDGE_WITH_DIGIT indicating the addition of a digit mark area (NO in step S1714), the processing proceeds to step S1715.
In step S1715, the CPU 101 checks whether the grade type is JUDGE_MULTIPLE indicating the addition of as many point mark fields as the number of points. If the grade type is JUDGE_MULTIPLE indicating the addition of as many point mark fields as the number of points (YES in step S1715), the processing proceeds to step S1717.
