Next, the image processing unit 44 extracts an image corresponding to the portion written for each writer from the read image stored in the HDD 26. Further, in extracting the image corresponding to the portion filled in for each writer, the image processing unit 44 identifies the characteristics of each writer from the entry field for each writer in the present embodiment. In the present embodiment, the color when the writer fills in each entry field is specified as a feature. That is, since it is considered that each writer fills in the answer sheet 50 in a single color, by extracting the image for each color from the scanned image, the image corresponding to the part filled in for each writer can be obtained. Be extracted. Specifically, an image of the area corresponding to the position of the answerer entry field 54 is extracted, and the most common color excluding the background color in the extracted image is specified as the characteristic of the writer. Then, by extracting the image corresponding to the specified color from the scanned image, the image corresponding to the portion filled in by the answerer is extracted. Further, the image of the area corresponding to the position of the grader entry field 56 is extracted, and the most common color excluding the background color in the extracted image is specified as the characteristic of the writer. Then, by extracting the image corresponding to the specified color from the scanned image, the image corresponding to the portion filled in by the grader is extracted. Further, an image of the area corresponding to the position of the commenter entry field 58 is extracted, and the most common color excluding the background color in the extracted image is specified as the feature of the writer. Then, by extracting the image corresponding to the specified color from the scanned image, the image corresponding to the portion entered by the commenter is extracted. For example, as shown in FIG. 7, the answerer fills in the answerer entry field 54 in black, the grader fills in the grader entry field 56 in red, and the commenter fills in blue in the commenter entry field 58. If so, identify each color as a feature of the writer. In the example of FIG. 7, the characteristics of the answerer are specified as black, the characteristics of the grader are specified as red, and the characteristics of the commenter are specified as blue.

Further, the image processing unit 44 temporarily stores the image extracted for each writer in the HDD 26, and then performs character recognition processing (so-called OCR (Optical Character Recognition / Reader)) as necessary. For example, the student ID is specified by performing character recognition processing on the image corresponding to the answerer entry field 54.

Further, the images extracted for each writer are temporarily stored in the HDD 26, and then the extracted images are combined and combined according to the return contents specified in advance when instructing the reading of the answer sheet 50, and as shown in FIG. , Is transmitted to the server 16 and stored in the HDD 16d or the like as a storage unit of the server 16. When storing in the server 16, for example, the student ID read from the answer sheet 50, the task ID specified on the answer registration screen, and the like are stored in the folder corresponding to the folder. As a result, by accessing the server 16 from the information processing apparatus 14, the information stored in the server 16 can be confirmed as the returned answer sheet 50. As a return pattern in which the extracted images are combined, for example, as shown in FIG. 8, when the read image as it is is returned, only the answer and the comment are returned, only the answer is returned, and no return is made. In some cases, only comments may be returned, or only scoring may be returned.

Subsequently, specific processing performed by the control unit 20 of the image processing system 10 according to the present embodiment configured as described above will be described. FIG. 9 is a flowchart showing an example of the flow of processing performed by the control unit 20 of the image processing system 10 according to the present embodiment.

Extraction is performed, and the process proceeds to step 104. That is, since the positions of each entry field of the answer sheet 50 are predetermined as shown in FIG. 4 (B), the image corresponding to the region of the predetermined position is extracted.

In step 104, the control unit 20 determines whether or not an extraction abnormality has occurred. The determination determines whether or not an abnormality has occurred during the process of step 102, and if the determination is denied, the process proceeds to step 106, and if the determination is affirmative, the process proceeds to step 126.

In step 106, the control unit 20 controls the image processing unit 44, performs character recognition processing from the images in the answerer entry field 54 and the grader entry field 56, recognizes the characters, and proceeds to step 108.

In step 108, the control unit 20 determines whether or not an abnormality in character recognition has occurred. The determination determines whether or not an abnormality has occurred during the process of step 106, and if the determination is negative, the process proceeds to step 110, and if the determination is affirmative, the process proceeds to step 126.

In step 110, the control unit 20 controls the image processing unit 44, identifies the most abundant color components from the color components in each extracted image excluding the background, and proceeds to step 112. That is, by specifying the most colors other than the background for each of the entry fields, the color used when the entry is entered is specified as the characteristic of the entry.

In step 112, the control unit 20 determines whether or not an abnormality has occurred in specifying the color. The determination determines whether or not an abnormality has occurred during the process of step 110, and if the determination is negative, the process proceeds to step 114, and if the determination is affirmative, the process proceeds to step 126.

In step 114, the control unit 20 controls the image processing unit 44 to extract an image of a specific color from the scanned image to generate an answer image, a scoring image, and a comment image, and proceeds to step 116. .. That is, by judging and extracting the image entered by each writer from the color characteristic of the writer, an answer image, a scoring image, and a comment image are generated and temporarily stored in the HDD 26 as an image for each writer. do.

In step 116, the control unit 20 determines whether or not an abnormality has occurred in generating the image. The determination determines whether or not an abnormality has occurred during the process of step 114, and if the determination is denied, the process proceeds to step 118, and if the determination is affirmative, the process proceeds to step 126.

In step 118, the control unit 20 controls the image processing unit 44 to generate a returned image synthesized by combining the images extracted according to the designated return method, and proceeds to step 120. That is, a return image is generated by combining and synthesizing the extracted images according to the return method set in advance on the answer registration screen.

In step 120, the control unit 20 determines whether or not an abnormality has occurred while generating the returned image. The determination determines whether or not an abnormality has occurred during the process of step 118, and if the determination is denied, the process proceeds to step 122, and if the determination is affirmative, the process proceeds to step 126.

In step 122, the control unit 20 controls the communication line I / F36 and transmits the extracted image, the character recognition result, the generated return image, and the registration information set on the answer registration screen to the server 16. Move to 124. Note that step 122 corresponds to the output unit.

In step 124, the control unit 20 determines whether or not there is still an answer sheet 50 to be read. In the determination, for example, it is determined whether or not the answer sheet 50 to be read remains in the document reading unit 52, and if the determination is affirmed, the process returns to step 100 and the above processing is repeated, and the determination is negative. If so, the series of processes is terminated.

On the other hand, in step 126, the control unit 20 controls the display control unit 28, notifies the abnormality, and ends a series of processes. For example, by displaying the content corresponding to the generated abnormality on the user interface 22, the occurrence of the abnormality is notified.

In step 200, the CPU 16a determines whether or not the image forming apparatus 12 has requested the registration of the answer sheet 50. If the determination is affirmed, the process proceeds to step 202, and if the determination is negative, the process proceeds to step 204.

In step 202, the CPU 16a stores the registration information (teacher ID, assignment ID, etc.) and the character recognition result (student ID, scoring result, etc.) in the corresponding folder created in advance in the HDD 16d, and ends a series of processes. .. That is, the information transmitted from the image forming apparatus 12 is stored in the folder in the HDD 16d.

On the other hand, in step 204, the CPU 16a determines whether or not the information processing apparatus 14 has requested to view the returned image. If the determination is affirmed, the process proceeds to step 206, and if the determination is denied, a series of processes are terminated and processes corresponding to other requests are performed.

In step 206, the CPU 16a reads the information corresponding to the instruction from the HDD 16d, transmits the information to the requesting information processing apparatus 14, and performs a series of processes. As a result, the information processing apparatus 14 displays the returned image transmitted from the server 16.

By the way, in the present embodiment, even if the answerer erroneously fills in a color different from that of the answerer of the other answer sheet 50, the part filled in by the answerer is obtained by extracting the image of the color filled in by the answerer. The image is extracted, but it is different from other answer sheets. Therefore, if the answer sheet is filled in in a color different from that of the other answer sheet 50, it may be provided with a function of correcting the color of the extracted image. For example, in step 122 of FIG. 9, a process of correcting the color may be added before transmitting the extracted image to the server 16. FIG. 11 is a flowchart showing an example of the flow of additional processing performed when the answer sheet is filled in in a color different from that of the other answer sheets 50. The process of FIG. 11 is added between steps 116 and 118, for example.

Specifically, in step 117A, the control unit 20 compares the colors of the answer image, the scoring image, and the comment image generated in step 114 with the other answer sheets 50, and proceeds to step 117B. do.

In step 117B, the control unit 20 determines whether or not each of the compared images has a different color from the other answer sheets 50. If the determination is affirmed, the process proceeds to step 117C, and if the determination is negative, the process of FIG. 11 is returned and the process proceeds to step 118 of FIG.

In step 117C, the control unit 20 corrects the color of the image so that the color of the image is different from that of the other answer sheet 50 is the same as that of the other answer sheet 50, and the process of FIG. 11 is performed. Return to step 118 in FIG.

By adding the process in this way, even if the writer fills in the wrong color, when registering in the server 16, the color is corrected to the same color as the other answer sheets 50 and registered.
