[1] Configuration FIG. 1 is a block diagram showing a configuration of a system 1 according to the present embodiment. The system 1 includes an image processing device 10 and a server 20. The image processing device 10 performs image processing such as an image forming process for forming an image on a medium and an image reading process for reading an image formed on the medium. The image processing device 10 is connected to the server 20 by the communication line 2. The communication line 2 includes, for example, at least one of the Internet, a mobile communication network, a telephone line, a LAN (local area network), and the like. The server 20 provides various services such as a storage service.

FIG. 2 is a block diagram showing an example of the functional configuration of the image processing device 10. The image processing device 10 includes an output means 11, a recognition processing means 12, an output control means 13, a pre-processing means 14, and a reception means 15. The output means 11 has, as the scanning result of the document to be read, image data of the first resolution representing the image of the document and partial image data representing the image of the region included in the document and having the first resolution. Outputs partial image data with a second resolution higher than that.

In this embodiment, the output of the image data and / or the partial image data by the output means 11 includes the output to an external device (for example, a server 20, an external storage device, etc.) of the image processing device 10, and the device. Contains output to internal memory.

The recognition processing means 12 performs recognition processing including at least one of character recognition processing and image recognition processing on the partial image data. In this embodiment, the image recognition process is a process of analyzing an image and recognizing the shape and attributes of an object included in the image by performing pattern matching or the like. The image recognition process is, for example, a two-dimensional barcode reading process, a face recognition process, and a face authentication process. The output control means 13 performs output control corresponding to the condition information acquired by the recognition process by the recognition process means 12. The preprocessing means 14 performs preprocessing on the partial image data, including at least one of edge enhancement processing, color conversion processing to a single color, binarization processing, white area detection processing, and white area removal processing. In this embodiment, the white area is a monochromatic area such as white (that is, a background area that does not include characters or images). The receiving means 15 accepts the user's designation of the first resolution.

FIG. 3 is a diagram illustrating a hardware configuration of the image processing device 10. In the figure, the memory 151 stores various data. The processor 152 performs data processing according to the program stored in the memory 151. The communication IF 153 is an interface for performing data communication with an external device via a network. The UI unit 154 includes, for example, a touch screen and keys. The image forming unit 155 forms an image on a medium such as paper by an electrophotographic method. The image reading unit 156 (an example of an image reading device) optically reads an image of a document (medium). The image processing unit 157 includes, for example, a DSP (Digital Signal Processor) or a GPU (Graphics Processing Unit), and executes various image processing. The paper feeding unit 158 supplies a medium such as paper to the image forming unit 155.

In this example, the function shown in FIG. 2 is implemented by executing the program stored in the memory 151 by the processor 152 or the image processing unit 157. The processor 152 or the image processing unit 157 executing the program is an example of the output means 11, the recognition processing means 12, the output control means 13, the pre-processing means 14, and the reception means 15.

[2] Operation First, the user inputs a user ID assigned to himself / herself using the UI unit 154 and performs an operation of instructing an image reading process. In this instruction, the resolution related to the reading process and the output destination (for example, a storage server) may be specified by the user. The UI unit 154 outputs information according to the operated content, and the processor 152 performs user authentication by inquiring the user ID, for example, to the server 20. The server 20 authenticates the user according to whether the user ID is registered in the user management database stored in advance, and notifies the image processing device 10 of the result. If the authentication is successful, the processor 152 starts the image reading process according to the information output from the UI unit 154. First, the processor 152 displays a screen for designating the arrangement of disclosure conditions in the manuscript on the UI unit 154. If the user authentication fails, the image processing device 10 may display a message to that effect on the UI unit 154.

FIG. 4 is a diagram showing an example of a document to be read as an image. In the example of the manuscript of FIG. 4, the disclosure conditions are described in the area A1. In this embodiment, the disclosure condition is information that restricts the disclosure of a document (hereinafter, simply referred to as “document”) in which an image is formed in the manuscript. As the disclosure conditions, for example, the disclosure level, the disclosure range, the designated period, and the creation date are used. In the example of FIG. 4, "disclosure scope: sales department", "designated period: 2 years", "creation manager: Fujitaro", and "creation date: 2016.11.11" are described as disclosure conditions.

FIG. 5 is a diagram showing an example of the screen S1 displayed on the UI unit 154. The screen S1 displays a screen for the user to specify the position of the disclosure condition in the scanned medium. On the screen S1 of FIG. 5, for example, a message such as "Please specify the position where the disclosure condition is arranged" may be displayed.

When the manuscript contains disclosure conditions, the user performs an operation of designating the position (area) of the disclosure conditions. In the example of FIG. 5, an example in which the user specifies the four corners of the document is shown as the position where the disclosure condition is described. The number of areas specified by the user may be one or plural. When the position is specified by the user, the processor 152 stores information indicating the specified position (hereinafter referred to as "location information") in the memory 151.

FIG. 6 is a flowchart showing the flow of processing performed by the image processing apparatus 10. In step S101, the processor 152 instructs the image reading unit 156 to read the image. The image reading unit 156 reads the image of the original according to the instruction of the processor 152.

At this time, when the resolution specified by the user is lower than the predetermined resolution (for example, 400 dpi), the image reading unit 156 is determined in advance instead of the resolution specified by the user (first resolution). Image data is generated by scanning the image at the same resolution (second resolution). For example, when the predetermined resolution is 400 dpi and the user specifies the resolution as 200 dpi, the image reading unit 156 reads the image at 400 dpi. On the other hand, when the resolution specified by the user is equal to or higher than a predetermined resolution, the image reading unit 156 reads the image at the resolution specified by the user and generates image data having the specified resolution.

In this embodiment, the predetermined resolution (second resolution) is the resolution allowed in the recognition process (character recognition process, etc.) described later (resolution assumed to be successful in the recognition process) (for example, 400 dpi). Is.

In step S102, the image processing unit 157 performs correction processing such as tilt correction and shading correction on the image data generated by the image reading unit 156. In step S103, the image processing unit 157 performs various filtering processes on the image data. It should be noted that these correction processes and filter processes are processes performed by an existing image processing device.

In step S104, the image processing unit 157 extracts the area indicated by the arrangement information specified by the user, and generates partial image data representing the image of the extracted area. By this process, the partial image data of the area designated as the area of the disclosure condition by the user is extracted. In the following description, for convenience of description, data representing an image in a region designated by the user is referred to as "partial image data". Further, the data representing the image of the entire scanned document is called "image data".

The image processing unit 157 performs preprocessing (processing in steps S105 to S107) on the extracted partial image data. In this embodiment, the pre-processing is a process for improving the recognition accuracy of the recognition process described later. For example, edge enhancement processing, color conversion processing, binarization processing, white area detection processing, and white area removal processing are performed. Including. First, in step S105, the image processing unit 157 performs edge enhancement processing on the partial image data. Further, the image processing unit 157 uses a predetermined look-up table (LUT) to obtain image data in the RGB color space obtained by reading the image of the image reading unit 156, which is one of the uniform color spaces L * a. * B Perform color conversion processing to convert to image data in space. Next, in step S106, the image processing unit 157 performs binarization processing on the partial image data.

In step S107, the image processing unit 157 performs detection processing and removal processing of the white area on the partial image data. In this embodiment, the white area becomes an unnecessary area for character recognition and is therefore removed. In step S108, the image processing unit 157 outputs (stores) the partial image data that has been subjected to the white area removal processing to the memory 151. As described above, in this embodiment, the partial image data of the region designated by the arrangement information is subjected to image processing (processing of steps S105 to S107) suitable for the character region, and the partial image is subjected to image processing. The data is stored in the memory 151.

The partial image data stored in the memory 151 is used when the processor 152 performs the recognition process. In this embodiment, the recognition process is a process of recognizing a character, an image (for example, a two-dimensional barcode), or the like, and includes, for example, at least one of a character recognition process and an image recognition process.

FIG. 7 is a flowchart showing the flow of processing performed by the processor 152. In step S201, the processor 152 performs recognition processing on the partial image data stored in the memory 151, and acquires the condition information from the partial image data. In this example, the processor 152 performs character recognition processing such as OCR on the partial image data, and acquires condition information from the partial image data.

In this embodiment, the condition information is information indicating a condition for permitting or prohibiting the processing of image data. The condition information includes, for example, information indicating the disclosure conditions (disclosure level, disclosure range, specified period, creation date, etc.) of the document represented by the image data, information indicating the output destination device and memory, and information indicating the output timing. Including. The processing of step S201 of FIG. 7 by the processor 152 and the processing of steps S109 to S112 by the image processing unit 157 are executed in parallel.

Returning to the description of FIG. The image processing unit 157 performs the processing of steps S105 to S108 described above on the partial image data, and also performs the processing of steps S109 to S112 on the image data representing the image of the original. The series of processes in steps S105 to S108 and the series of processes in steps S109 to S112 may be executed in parallel.

In step S109, the image processing unit 157 converts the resolution of the image data from the second resolution (for example, 400 dpi) to the first resolution (for example, 200 dpi). In step S110, the image processing unit 157 uses a predetermined look-up table (LUT) to convert the resolution-converted image data (RGB color space image data) into L * a, which is one of the uniform color spaces. * Convert to image data in b space. In step S111, the image processing unit 157 compresses the image data. In step S112, the image processing unit 157 outputs (stores) the compressed image data to the memory 151. As a result, image data having the first resolution (for example, 200 dpi) is stored in the memory 151.

On the other hand, in step S202 of FIG. 7, the processor 152 performs output control corresponding to the acquired condition information on the image data stored in the memory 151. Specifically, in this embodiment, the processor 152 acquires the disclosure condition information representing the disclosure condition from the partial image data, and when the condition indicated by the acquired disclosure condition information restricts the disclosure of the document. Limit the output of image data. On the other hand, when the condition indicated by the acquired disclosure condition information permits disclosure, the processor 152 permits the output of image data.

In this embodiment, the processor 152 controls the output of image data according to disclosure conditions such as disclosure level, disclosure range, user ID, device information, designated period, creation date, and scanning date and time. In this output control, a predetermined database may be referred to. This database may be provided on the server 20.

FIG. 8 is a diagram showing an example of disclosure conditions. In the example of FIG. 8, the case where the disclosure level described in the manuscript is “Internal Use Only” and the disclosure range is “Sales Department” is shown. Further, in this example, it is assumed that the user identified by the user ID does not belong to the XX section and the installation location of the image processing device 10 is not the XX section. In this case, the processor 152 inquires the server 20 whether the user identified by the user ID input by the user belongs to the "sales department". The server 20 searches a predetermined user management database to determine whether or not the user identified by the user ID belongs to the "sales department" according to the information received from the image processing device 10. If the user belongs to the "sales department", it is determined that disclosure is permitted. On the other hand, if the user does not belong to the "sales department", it is determined that disclosure is prohibited. The server 20 notifies the image processing device 10 of the determination result.

The processor 152 of the image processing device 10 determines whether the disclosure of the manuscript is permitted according to the data received from the server 20. If it is determined that the permission is permitted, the processor 152 performs a process of outputting the image data stored in the memory 151 to an output destination (for example, a storage server) specified by the user or a predetermined output destination. .. On the other hand, when it is determined that the disclosure is not permitted, the processor 152 displays a message to that effect on the UI unit 154, or performs an image forming process for forming the message to that effect on the medium. , Outputs information to that effect.

FIG. 9 is a diagram showing an example of a screen displayed on the UI unit 154, and FIG. 10 is a diagram showing an example of a medium on which a message is image-formed. In the example of FIG. 9, the message "Scan prohibited is out of the disclosure range" is displayed on the UI unit 154. In the example of FIG. 10, the message "scan prohibited is out of the disclosure range" is formed on the medium. As illustrated in FIG. 10, the image formed on the medium may be an image in which a grayscale rectangular image is superimposed on the image data stored in the memory 151.

FIG. 11 is a diagram showing another example of disclosure conditions. In the example of FIG. 11, the case where the designated period written in the manuscript is "2 years" and the acquired creation date is "2016.11.11" is described. Further, in this example, it is assumed that the date and time when the image reading is instructed has passed the disclosure deadline. In this case, first, the processor 152 determines whether the current date and time has passed two years or more from the creation date. If more than two years have passed, it is determined that the disclosure deadline has passed. On the other hand, if it has not passed, it is determined that the disclosure deadline has not passed.

When it is determined that the disclosure deadline has not passed, the processor 152 outputs the disclosure data stored in the memory 151 to an output destination (for example, a storage server) specified by the user or a predetermined output destination. I do. On the other hand, when it is determined that the disclosure deadline has passed, the processor 152 displays a message indicating that effect on the UI unit 154, or performs an image forming process for forming a message indicating that effect on the medium. , Outputs information to that effect.

FIG. 12 is a diagram showing an example of a screen displayed on the UI unit 154, and FIG. 13 is a diagram showing an example of a medium on which a message is image-formed. In the example of FIG. 12, the message "The scan prohibition disclosure deadline has passed" is displayed on the UI unit 154. In the example of FIG. 13, the message "scan prohibited disclosure deadline has passed" is formed on the medium. By checking the screen displayed on the UI unit 154 and the image formed on the medium, the user grasps that the disclosure of the document instructed to read the image is restricted.

By the way, in general, in order to perform character recognition processing such as OCR, it is preferable that the resolution of the target image data is 300 to 400 dpi. In particular, characters indicating disclosure conditions such as disclosure level and disclosure range are often written in a small font, and in order to recognize these character strings and determine whether or not disclosure is possible, a certain high resolution (for example, 400 dpi) is used. The above) is required. However, in general, in the image reading process, image data of 150 to 200 dpi may be generated in consideration of the file size and the like. Further, since the resolution of the scanned image is set by the user, the image data may not have a resolution suitable for character recognition.

In addition, manuscripts such as in-house documents may be created with a predetermined template, and the position where disclosure conditions such as the disclosure range are described is determined for each template. In this embodiment, the partial image data of the area designated by the user as the disclosure condition is stored in the memory 151 at a resolution suitable for the recognition process (second resolution), and the image of the entire document is represented. The image data is stored in the memory 151 at a first resolution lower than the second resolution. As a result, the amount of image data that is the scanning result of the image scanning is smaller than that in the case where the image data obtained by scanning the entire document at the second resolution is stored in the memory 151. Further, since the area to be processed by the recognition process is a part, the time required for the recognition process and the output control process using the recognition result is shortened.
