Reference numeral 105 denotes an output unit that outputs a result processed by the processing unit 104.

Note that each functional block such as the image input unit, the region symbol detection unit, the region extraction unit, and the processing unit may be typically realized as an LSI that is an integrated circuit. The method of circuit integration is not limited to LSI. These may be individually made into one chip, or may be made into one chip so as to include a part or all of them.

FIG. 2 is a control schematic diagram of the form processing apparatus according to Embodiment 1 of the present invention. In an image input step S101, an image including a processing target area is input, and the process proceeds to S102. In area symbol detection step S102, a start symbol, an end symbol, and a ruled line are detected from the input image, and the position, height, direction, and type of the start symbol and end symbol are detected, and the process proceeds to S103.

In the area symbol verification step S103, the shape, combination, and positional relationship of the start symbol, the end symbol, and the ruled line are verified. If it is not possible, the process proceeds to S101, and if it is possible, the process proceeds to S104. In the region image extraction step S104, the processing target region image is extracted. If the processing target region image has been deformed, the process proceeds to S105, and if not, the process proceeds to S106, S107, S108 depending on the item.

Each step may be described by a program that can be executed by a computer.

FIG. 3 is a configuration diagram of the form in the first embodiment of the present invention. It consists of an entry sheet (FIG. 3 (a)) and a copy sheet (FIG. 3 (b)) and satisfies the following conditions.
The processing target area is surrounded by a start symbol, an end symbol, and a ruled line.
-The start symbol and the end symbol are surrounded by a certain undescribed region (white or background color).
The start symbol and the end symbol express the existence direction and height of the processing target area.
-The shape of the start symbol and end symbol differs depending on the processing content in the item column.
-The entry sheet shows the entry position in the processing target area and is not described on the copy sheet.
-Provide a certain unrecorded area between the start symbol, end symbol, entry position, and ruled line.
-The copy sheet start and end symbols are smaller than the corresponding entry sheet start and end symbols.

□ For packaged items with slips, the entry sheet is kept at the client, and only the copy sheet is attached. Hereinafter, the details of the operation will be described by taking the input image of the copy sheet C of the form A shown in FIGS. 4A to 4C as an example. When the copy sheet C is photographed by the camera in the image input unit 101, the image is input with the inclination θ degree and the resolution Ddpi as shown in FIG.

The region symbol detection unit 102 extracts a connected closed region of the input image, performs shape matching with the start symbol and end symbol registered in advance as shown in FIG. Detect the position, height, direction, and type of symbols and end symbols. The detection result is shown in FIG.

<Start symbols LS1, LS2, LS3 and end symbols LE1, LE2, LE3 could be detected. In the copy sheet, since the start symbol and the end symbol are written smaller than the entry sheet, it is easy to detect as a connected closed region.

In the area extraction unit 103, as shown in FIG. 6A, the form layout of the copy sheet C is registered in advance.

In the form layout, the processing content, the shape of the start / end symbol, the size of the processing area, and the entry position in the processing area are registered for each item. With respect to the start symbol extracted by the region symbol extraction unit 102, an end symbol that is paired with the direction of the start symbol is specified. If it cannot be specified, the process returns to the processing of the image input unit 102.

It is verified that LS1 and LE1, LS2 and LE2, LS3 and LE3 are paired. If the pair of start symbol and end symbol is known, the position of the processing target area is specified from the position, height and direction of the start symbol and end symbol. And cut out. FIG. 6B shows the result of specifying the position of the processing target area L1 of the start / end symbol pair LS1 and LE1.

Next, an angle correction method when the copy sheet C is read obliquely will be described. The inclination θ and the resolution D of the processing target area image can be obtained by the expressions shown in FIGS. 8 cm in FIG. 7B is the horizontal width of the postal area size stored in the form layout in FIG. Even if the start / end symbol of the pair can be detected, if the resolution is too low or too high, it is impossible to return to the processing of the image input unit 102. When the slope θ has a value, the processing target area image is rotationally corrected. FIG. 7C shows the processing target area image extracted.

The processing unit 104 performs processing corresponding to the item indicated by the start symbol for each extracted processing target region image. Since the processing target region image L1 shown in FIG. 7C is a zip code item from the form layout shown in FIG. 6A, the character image is used by using the information on the character description position in the registered item. To recognize characters.

Also, if it is a selected symbol item, the selected symbol is identified using the information of the symbol description position in the registered item. The output unit 105 outputs the processing results of these processing units 104.

According to such a configuration, the start symbol and the end symbol are described in the processing target area of the form, and the start symbol and the end symbol of the item are extracted from the input image of the form by providing the area processing unit in the form processing apparatus. Since the position of each item in the input image is specified and processing is performed for each item, even when a form image is input with an image input device such as a camera where the form photographing state is unstable, each item is accurately processed at high speed. Processing for each item can be performed.

Furthermore, the effect of changing the size of the start symbol, etc. on the entry sheet and copy sheet will be described using FIG. FIG. 8A shows an entry sheet on which an entry frame (solid line) is printed together with a start symbol and the like.

FIG. 8B shows a copy sheet. Since the copy sheet (b) is directly below the entry sheet, the entry frame (solid line) of the entry sheet is at the position of the dotted line on the copy sheet. Actually, the dotted line is not printed.

When “a” is entered so as to cover the character entry frame (solid line) of the entry sheet (a), “a” is copied to the position of FIG. 8B on the copy sheet.

At this time, since the start symbol on the copy sheet is smaller than the start symbol on the entry sheet and is printed away from the entry frame, the entered characters do not cover the start symbol. For this reason, character recognition can be performed easily.

Furthermore, the case where the characters in the start symbol of the entry sheet and the copy sheet are printed is described with reference to FIG. In FIG. 9, as shown in the entry sheet (a), the start symbol has a postal mark, but is not printed on the copy sheet (b).

For this reason, when printing on an entry sheet, the user can grasp the contents of entry, and when reading a copy sheet with a computer, since there is no symbol, it is easy to detect the start symbol by image processing. .

In the present embodiment, the copy sheet is the processing target, but the entry sheet may be the target. When the entry sheet is a processing target and the entry sheet is input as an image, a process of deleting the image at the entry position indicated by using the entry position information in the item may be added.

The start / end symbols, ruled lines, and notation indicating the entry position may be printed in different colors.
The shape of the start / end symbol is not limited to this. A plurality of start / end symbols may be arranged at the outer peripheral position of the processing target area in order to cope with the case where the shape of the processing target area is complicated.

The processing target area image is corrected in accordance with the correction, and when the processing target area is deformed, the processing target area image is corrected. A processing unit 104 processes the contents described in the processing target area extracted by the area extracting unit 103 according to the type of start symbol and end symbol. Reference numeral 105 denotes an output unit that outputs a result processed by the processing unit 104.

Note that the functional blocks such as the image input unit, the region symbol detection unit, the blur degree detection unit, the region extraction unit, and the processing unit may be typically realized as an LSI that is an integrated circuit. The method of circuit integration is not limited to LSI. These may be individually made into one chip, or may be made into one chip so as to include a part or all of them.

FIG. 12 is a control schematic diagram of the form processing apparatus according to the second embodiment of the present invention. In an image input step S101, an image including a processing target area is input, and the process proceeds to S102. In area symbol detection step S102, a start symbol, an end symbol, and a ruled line are detected from the input image, and the position, height, direction, and type of the start symbol and end symbol are detected, and the process proceeds to S103.

In the area symbol verification step S103, the shape, combination, and positional relationship of the start symbol, the end symbol, and the ruled line are verified. If it is not possible, the process proceeds to S101, and if it is possible, the process proceeds to S201. In the blur degree detection step S201, a blur degree detection symbol is detected from the input image that has been input to determine the blur degree, and the process proceeds to S202. In the blurring degree verification step S202, the blurring degree is verified, and if the blurring degree is larger than a preset value, the process proceeds to S101, and if not, the process proceeds to S104. In the region image extraction step S104, the processing target region image is extracted. If the processing target region image is blurred or deformed, the process proceeds to S105. If the processing target region image is not blurred or deformed, the processing proceeds to S106 and S107 depending on the item. , S108.

In region image correction step S105, the region image to be processed is subjected to blur correction or deformation correction, and the process proceeds to S106, S107, and S108 depending on the item.

In the image storage step S108, the processing target area image is converted into image data, and the process proceeds to S109. In the output step S109, the results processed in the character recognition step S106, the symbol recognition step S107, and the image storage step S108 are output.

Note that each step may be described by a program executable by a computer.

The configuration of the form in the second embodiment is the same as the form in the first embodiment except for the blur degree detection symbol.

FIG. 13 is an explanatory diagram of a form blur degree detection symbol in the second embodiment of the present invention. The start symbol, end symbol, and postal “-” in the entry sheet are normal notations (FIG. 13A). A symbol for detecting the degree of blur is shown in the start symbol, end symbol, and postal “-” notation position of the copy sheet (FIG. 13B).

Hereinafter, although the details of the operation of the second embodiment will be described, the operations of the image input unit 101, the region symbol detection unit 102, the processing unit 104, and the output unit 105 are the same as the operations of the respective units in the first embodiment.

FIG. 14 (a) is a diagram in which a postal code is entered on an entry sheet, and FIG. 14 (b) is an input image when a copy sheet is photographed with a camera, and blurring occurs at the time of photographing. The blur degree detection unit 201 identifies the position of the blur degree detection symbol from the input image input by the image input unit 101 using the positions of the start symbol and the end symbol detected by the region symbol detection unit 102, and detects the blur degree. Cut out the symbol image. The blur degree is detected from the image diffusion state of the blur degree detection symbol. Since a plurality of blur degree detection symbols are described, it is possible to detect a difference in blur degree depending on the form position. If the degree of blur is equal to or greater than a preset value, the process returns to the image input unit 101.
