  As described above, various techniques have been proposed in which various data included in a document are classified according to type (attribute), that is, categorized and classified and stored as data in which attributes are associated with a storage unit such as a database. However, there is a limit to automating the attribute determination process for the document area included in the document document, and the attribute determination and setting process itself requires processing by a person (operator).

  When attribute determination is performed based on the operator's determination, for example, the date data portion is colored with a red marker, and the document name data portion is colored with a blue marker, based on correspondence information between preset marker colors and attributes. The operator uses the markers of various colors to set the marker colors for the characters on the document.

  Next, the document in which the marker color is set is read by the color scanner, the marker color on the document is discriminated, and the character information to which the marker color is added is decoded by OCR (Optical Character Recognition). Further, when the decrypted character information is stored as text data in the database, an attribute discriminated from the marker color, for example, attribute information such as date and document name is stored in association with the attribute value corresponding to the text data. This process is called a character string extraction / attribute assignment process using a marker pen.

  In such character string extraction / attribute assignment processing using the marker pen, the marker color setting processing is executed by the operator. Therefore, it is impossible to eliminate all mark mistakes. If the operator notices a mark error, the operator re-outputs the original document without any additional writing by the marker and redoes all the mark settings again, or displays the scanned image on a display such as a PC and prints the original image one by one. It was necessary to perform processing such as censoring, checking for errors, and appropriately changing attribute values stored in the database.

  According to the configuration of the present invention, for example, a character string extraction / attribute assignment process using a marker pen for a document document, that is, a marker color is analyzed from a postscript document added with a color marker, and document information based on the marker color is analyzed. In the configuration for executing the attribute determination process, the color information on the postscript document is acquired, and the extracted color region is analyzed for a color region having a plurality of different color contact regions to identify the correct marker color It was. Specifically, after recording the erroneously recorded marker color, the correct marker color is recorded according to a predetermined rule, and an analysis algorithm corresponding to the recording rule is applied to determine the correct marker color Therefore, efficient and reliable character string extraction / attribute assignment processing with a marker pen can be performed without performing reprocessing such as re-setting of all marker colors.

  Details of an information processing apparatus, an information processing method, and a computer program according to embodiments of the present invention will be described below with reference to the drawings.

  First, an outline of character string extraction / attribute assignment processing using a marker pen will be described with reference to FIGS. 1 and 2. Character string extraction / attribute assignment processing using a marker pen performs, for example, a process in which an operator checks information such as a character string on a document with a marker of a specific color set according to a category for a document document, In this process, the document after this processing is read by the scanner, the marker color is discriminated from the read image data, the information on the document is classified, and stored in the database as index information for the document.

For example, if the document is a product quote, etc., depending on the color of the marker,
Orange: Client,
Green: Purchased item
Blue: purchase price,
Red: Respondent,
The marker colors used in advance are associated with each other according to the type of information, and the operator selects information corresponding to these pieces of information from the document, and checks with the markers assigned to each. Thereafter, in an information processing apparatus such as a PC, the color information of the marker is acquired from the image data read by the scanner, and the document information of the indicated portion of each color information is converted into data by, for example, character recognition (OCR) processing. And stored in the database as index information corresponding to the document document.

  For example, the information processing apparatus 51 illustrated in FIG. 1 outputs a document document stored in the database 54 via the printer 52. This is an original document 11 shown in the figure. The operator adds information to the original document 11 using a marker based on the correspondence between the preset information type and the use marker color. This result is the postscript document 12 shown in the figure.

For example, red, blue, and green markings 21 to 23 are made on the postscript document, and these are marked based on a predetermined rule. For example, the correspondence between the marker color and the information type (attribute)
Orange: Client,
Green: Purchased item
Blue: purchase price,
Red: Respondent,
Is set as The postscript document 12 is read by the scanner 53 and subjected to data processing in the information processing apparatus 51, and index information setting processing corresponding to the processing target document document is performed.

With reference to FIG. 2, a specific example of character string extraction / attribute assignment processing by the marker pen executed in the information processing apparatus 51 will be described. The postscript document 100 shown in FIG. 2 is the postscript document 100 in which the marker color is set by the operator. The correspondence between marker colors and attributes
Orange: Client,
Green: Purchased item
Blue: purchase price,
Red: Respondent,
It is.

The marker color setting area 101 of the postscript document is an area in which the characters “scanner” are recorded. The operator determines that the attribute of the marker color setting area is “purchased product” and is set for the purchased product. Marker color is set using marker color = [green].
The marker color setting area 102 is an area in which the characters “ST123” are recorded. The operator determines that the attribute of the marker color setting area is [requester identifier (requester No.)], and asks the requester. Set the marker color using the marker color set to [Orange].

The marker color setting area 103 is an area in which the characters “Company B” are recorded. The operator determines that the attribute of the marker color setting area is “respondent”, and the marker color set for the respondent = Use [Red] to set the marker color.
The marker color setting area 104 is an area in which the characters “¥ 2120” are recorded. The operator determines that the attribute of the marker color setting area is “purchase price”, and the marker color set for the purchase price. = Use [Blue] to set the marker color.

The additional writing document 100 is read by the scanner 53 and input to the information processing apparatus 51, and character string extraction / attribute assignment processing is performed by the marker pen. The storage unit of the information processing apparatus 51 stores a marker color attribute correspondence table 71 indicating correspondence between marker colors and attributes shown in the figure. That is,
Marker color = Orange: Attribute = Requester
Marker color = green: attribute = purchased item,
Marker color = blue: attribute = purchase price
Marker color = red: attribute = respondent,
It is a table having correspondence information between these marker colors and attributes.

  The information processing apparatus 51 acquires marker color information from the image data read by the scanner, and refers to the marker color attribute correspondence table 71 to determine attributes such as character information in the setting area of each color information. The character information in the setting area of each color information is converted into text data by, for example, character recognition (OCR) processing and stored in the database 54 together with attribute values.

  An example of data stored in the database is analysis data 72 shown in the figure. The analysis data 72 is a table storing data classified for each attribute corresponding to each color of the color marker. As described above, the information processing apparatus 51 classifies and arranges the data read by the character string extraction / attribute assignment processing with the marker pen of each additional writing document for each attribute, and generates the analysis data 72 shown in the figure. Store in the database 54. Note that the analysis data 72 shown in the figure shows an example of data that can be generated by the character string extraction / attribute assignment process using the marker pen, and various other forms of data can be generated.

  Thus, efficient data organization is possible by the character string extraction / attribute assignment processing using the marker pen. However, as described above, it is a person (operator) who sets the marker color for each document, and there is a problem that the occurrence of a mark mistake cannot be avoided.

  When correcting a document in which a mark miss is detected, it is conceivable to perform a process of reprinting a new document with no mark set again and resetting all marks. However, when such a process is performed, if a large number of marker colors are set for one document, there is a trouble of rewriting all the marks again if any one of them is incorrect. In addition, mark mistakes may occur, which reduces processing efficiency.

  In one embodiment of the information processing apparatus according to the present invention, the additional writing information in which a mark mistake is detected is used as it is, and additional writing is performed with a correct color marker in a mark mistake area where an erroneous mark is set. To determine the correct marker color and register the attribute value. This processing example will be described with reference to FIG.

  FIG. 3 shows a postscript document 110 in which the operator sets a marker color for the same original as the postscript document 100 shown in FIG. 2, but the marker color setting area 201 is a mark miss area. Originally, the marker color setting area 201 is an area in which the characters “ST123” are recorded and is [requester identifier (requester No.)]. Therefore, the marker color set for the requester = [orange ], The marker color has to be set using a marker color [blue] corresponding to another attribute (purchase price), but the marker color has been set by mistake.

  In the processing configuration of the present invention, when such a mark missed document is detected, the additional document with the mark miss is applied as it is, and the operator overwrites the mark miss area with the correct marker color. Execute. The information processing apparatus according to the present invention determines the correct marker color by executing the analysis of the marker color setting area recorded in such a manner that the erroneous marker color and the correct marker color overlap or contact each other.

  The marker color analysis algorithm executed in the information processing apparatus according to the present invention includes a plurality of algorithms. In order to perform marker color determination according to these algorithms, a marker recording rule corresponding to the algorithm is applied. When the operator uses the correct marker color to overwrite the mark miss area, the operator performs the overwriting according to the marker recording rule corresponding to the marker color analysis algorithm executed by the information processing apparatus.

  One example of the marker recording rule is the marker recording rule 1 in FIG. In the example shown in FIG. 3A, the correct marker color [orange] (second additional recording) is set in the mark miss area where the marker color has been set using the wrong marker color [blue] (first additional recording color). In the case of overwriting using (color), the rule is that the correct marker color [orange] (second additional recording color) is recorded longer in the character string direction than the first additional recording color setting area. When recording the second additional recording color which is the correct marker color in this way, the rule is to record longer in the character string direction than the first additional recording color setting area.

  The information processing apparatus that executes the character string extraction / attribute assignment processing with the marker pen based on the analysis of the marker color, in accordance with the analysis algorithm corresponding to the recording rule for the second additional recording color, correct marker color [orange] (second additional recording color) ) Is detected.

As shown in FIG. 3A, the marker color setting area is
Wrong marker color [blue] (first additional color)
Correct marker color [orange] (second additional color)
Subtractive color mixture [purple] generated based on the overlap of two marker colors
These three different color regions are formed.
The subtractive color mixture is a color generated by a color mixture of a plurality of colors, and the color that is the source of the subtractive color mixture can be analyzed by color analysis using a CMYK color space, a Lab color space, or an RGB color space, for example. is there. Subtractive color mixing will be described in detail later.

  The information processing apparatus that executes the character string extraction / attribute assignment processing with the marker pen uses the first additional color (blue) and the second additional color (which are registered in advance in the table (corresponding table 71 shown in FIG. 2) as the marker color). The color that is not registered in the table as a marker color and the subtractive color mixture (in this case purple) of the registered marker color is the correct attribute color for the second additional color that is long in the character string direction. The character string extraction / attribute assignment process is executed by the marker pen that is determined and registered.

  Different examples of the marker recording rule will be described with reference to FIG. In FIG. 4B, the marker recording rule 2 is also processed for the mark miss area 201 in which the marker color is set using the wrong marker color [blue] (first additional recording color) of the additional recording document 110 shown in FIG. An example is shown.

  FIG. 4B is also an example in which the marker recording rule 2 is overwritten using the correct marker color [orange] (second additional recording color), and the correct marker color [orange] (second additional recording color) is set to the first marker color [orange] (second additional recording color). Recording an additional write color setting area as an area widened all around is an example of a second additional write color recording rule. The information processing apparatus detects the correct marker color [orange] (second additional recording color) according to the analysis algorithm corresponding to the recording rule for the second additional recording color.

In the processing example of FIG. 4B, the marker color setting area is
There is no region with only the wrong marker color [blue] (first additional color)
Correct marker color [orange] (second additional color)
Subtractive color mixture [purple] generated based on the overlap of two marker colors
These two different color regions are formed.

  An information processing apparatus that performs character string extraction / attribute assignment processing with a marker pen uses a color (orange) registered in advance in the table (corresponding table 71 shown in FIG. 2) as a marker color and a color that is not registered (here: When a non-registered color is detected as a subtractive color mixture of the registered color, the character string extraction / attribute assignment by the marker pen that registers and registers the registered color (orange) as the correct attribute color is detected. Execute the process.

In this way, the information processing apparatus performs subtractive color mixture analysis in the color analysis of the marker color setting area. The subtractive color mixture will be described with reference to FIG. In FIG.
(1) Generation state of subtractive color mixture in CMYK (or RGB) space (2) Generation state of subtractive color mixture in Lab space FIG.

  (1) In the diagram showing the occurrence of subtractive color mixture in CMYK (or RGB) space, each vertex is C (cyan), M (magenta), Y (yellow), K (black), R (red), G (Green), B (blue), and W (white) are shown. For example, the extracted color is the extracted color 241 shown in the figure. A region of a color generated when other colors are mixed with the extracted color is a region indicated by a rectangular parallelepiped shown in the drawing, and this region is a partial color space 242 in which subtractive color mixing is possible.

  That is, a partial color space having a possibility of subtractive color mixture is indicated by a rectangular parallelepiped having a straight line connecting the extracted color and black (K) as a diagonal line. Therefore, for example, when a color that is not registered in the table as the marker color is obtained from the scanner reading information, it is possible to analyze the color mixed in reverse from the partial color space that has the possibility of subtractive color mixing.

  For example, when the color read by the scanner is red (R) and red (R) is a color that is not registered in the table as a marker color, red (R) is registered in the table as a marker color. It can be determined that the color is generated by subtractive color mixture of a plurality of marker colors. It can be determined that the mixed color exists in the plane of M (magenta), Y (yellow), R (red), and W (white) in the CMYK (or RGB) space of FIG. For example, if the color registered in the table as the marker color is M (magenta) or Y (yellow), R (red) is a color generated by mixing colors of M (magenta) and Y (yellow). It can be determined that R (red) detected by the scanner is generated by mixing colors of M (magenta) and Y (yellow).

  FIG. 5 (1) is a diagram showing the occurrence of subtractive color mixing in the CMYK (or RGB) space, but not only in the CMYK (or RGB) space but also in the Lab color as shown in FIG. 5 (2). Also in the space, a partial color space 252 in which the conical region shown in the figure may be subtractively mixed can be defined as a color region generated when other colors are mixed with the extracted color 251. Thus, in various color spaces such as CMYK, RGB, and Lab, partial color spaces with the possibility of subtractive color mixture can be individually defined, and various settings are used for color information analyzed from information read by the scanner. Is possible.

  By applying the subtractive color mixing information described above, the information processing apparatus of the present invention analyzes the color information detected by the scanner, and for example, (a) Marker recording rule 1 described with reference to FIG. Alternatively, the correct marker color corresponding to the correct attribute value is determined from the marker color setting area recorded according to (b) marker recording rule 2 described with reference to FIG.

  In the color analysis of a scanned document, when the information processing apparatus of the present invention detects a color not registered in the table as a marker color, whether the detected color is a subtractive color mixture of the color registered in the table as the marker color The process which determines whether or not is executed. For this determination processing, for example, various color space information described with reference to FIG. 5 can be applied and sequentially analyzed. However, subtractive color mixture of colors registered in the table as marker colors in advance is possible. A table (mixed color information table) in which the color information generated as described above is generated, stored in the storage unit, and the color mixed information table is referred to when performing color analysis, thereby enabling efficient analysis. .

FIG. 6 shows an example of a color mixture information table in which color information generated as a subtractive color mixture of colors registered in the table as marker colors is registered. In this example of the color mixture information table, the colors registered in advance as marker colors are three colors of [green], [blue], and [orange]. A color generated by mixing these colors is registered.
The mixed color of green and blue is [Dark green]
The mixed color of green and orange is [Brown]
The mixed color of blue and orange is [purple]
These color mixture information is registered. The information processing apparatus that executes the marker color analysis refers to the color mixture information table in which the color mixture information is registered, executes a marker color analysis algorithm corresponding to each recording rule, and determines the correct marker color .

  A character string extraction / attribute assignment processing algorithm with a marker pen executed by the information processing apparatus will be described with reference to FIG. The flow shown in FIG. 7 is an algorithm for executing the analysis of the marker color setting area subjected to the recording process according to (a) the marker recording rule 1 shown in FIG. 3, and FIG. 8 shows a specific processing example of this analysis algorithm. FIG. The flow shown in FIG. 9 is an algorithm for executing the analysis of the marker color setting area subjected to the recording process in accordance with (b) marker recording rule 2 shown in FIG. 4, and FIG. 10 shows a specific processing example of this analysis algorithm. FIG.

  First, with reference to the flow shown in FIG. 7, an algorithm for executing the analysis of the marker color setting area subjected to the recording process according to (a) marker recording rule 1 shown in FIG. 3 will be described.

  First, the information processing apparatus inputs a scanned image in step S101. This scan image is a scan image including a marker color setting area subjected to recording processing in accordance with (a) marker recording rule 1 shown in FIG. In step S102, a character analysis (OCR) process is executed. In this character analysis, character analysis of the entire document may be performed, or character analysis may be performed by selecting only the marker color setting region and the subtractive color setting region based on the marker color.

  In step S103, a color extraction process is executed. A color different from the recorded color of the original background of the document and the original characters is extracted. The color extracted individually is not only the marker color registered in the table, but also a color different from the marker color not registered in the table, but it is a subtractive color mixture generated based on the marker color registered in the table. Corresponding colors are included.

  In step S104, it is determined whether each color extracted in step S103 is a marker color (registered color) registered in the table or an unregistered color (unregistered color).

  Next, in step S105, the original color of the color not registered in the table (non-registered color) is determined in the color determination in step S104. This original color determination processing is executed with reference to, for example, the color mixture information table described with reference to FIG. For example, when [purple] is extracted as the color extracted in step S103, and [purple] is a color that is not registered in the table (non-registered color), [purple] is registered marker colors [blue] and [orange]. The original color of [purple] is determined to be the registered marker colors [blue] and [orange].

  Next, in step S106, an integrated process of the registered color area and the mixed color area is executed. This integration process will be described with reference to FIG. The marker color setting area shown in FIG. 8 (1) is the same as the example shown in FIG. 3 (a) marker recording rule 1 described above with reference to FIG. 3, and the first registered marker color (blue) and the first Two registered marker colors (orange) and a subtractive color mixture (purple) of these registered marker colors are present in contact.

The marker color setting area 351 is an area that should not be provided with any marker color. In this example, the operator sets a mark using the registered marker color [blue] in this area.

  As a cancel rule for canceling such a marker color setting area, the marker cancel rule in FIG. 13D is set, and the operator cancels the marker according to this rule. The marker cancel example 371 shown in the figure is an example in which a predetermined cancel symbol is recorded at a position (character vicinity region) related to the setting region of the additional color marker. In the example shown in the figure, the cancel symbol is [Le]. The cancel symbol information is registered in an information processing apparatus that performs character string extraction / attribute assignment processing with a marker pen, and cancel processing is performed based on the registration information.
