Description

  The present invention relates to an image control apparatus and a program.

  Conventionally, as a technique for sequentially capturing images of books and recording the images sequentially, for example, when pages are sequentially turned by holding a book or the like, page turning is performed by analyzing each image continuously captured. A technique is known in which an image of each page is recorded and stored (see Patent Document 1). That is, the technique of Patent Document 1 detects the position change of the page edge because the position of the page edge sequentially changes in the image when pages are sequentially turned. When it is detected that the page is completely turned based on the above, the captured image at that time is acquired as an image for one page and recorded and saved.

JP 2012-65261 A

  However, in the method of detecting the position change of the page edge side as in the technique of the above-mentioned patent document, even if the page edge side can be detected at a location where the contrast is strong, it is difficult to always detect stably, There is also a possibility of causing erroneous detection of page turning by confusing the bent portion (vertical center line) between the facing pages with the edge of the page. In addition, when each page of the spread is photographed, data for two pages of spread is recorded and saved as data for one image.

An object of the present invention is to so that perform appropriate processing in accordance with the change of an image to be captured.

The first aspect of the present invention is an image control apparatus that controls an image, and detects a change in the image picked up by an image pickup means, and detects the change in the image by the detection means. When it is detected that there is no change in the image , a specifying means for specifying the image when the change is lost as a specific image, and whether the specific image specified by the specifying means is a document image of a spread page If the document image is a spread page document image, the specific image is divided into images of each page included in the image and stored independently. Storing control means for storing the image as an image of one page .

According to the present invention is to so that perform appropriate processing in accordance with the change of an image to be captured.

Hereinafter, embodiments of the present invention will be described with reference to FIGS.
FIG. 1 is a block diagram showing basic components of the information reading apparatus of the present embodiment.
The information reading device captures an information recording medium (for example, a paper medium such as a document) on which information is recorded and reads the information. The control unit 1 serving as the core of the information reading device supplies power from the power supply unit 2. And a central processing unit and a memory for controlling the overall operation of the information reading device according to various programs in the storage unit 3. The storage unit 3 includes a program memory 3a in which programs and various applications shown in flowcharts of FIGS. 6 and 7 to be described later are stored, and various types of information (for example, A work memory 3b for temporarily storing a flag or the like). Note that the storage unit 3 may include a recording medium such as an SD card, or may include a storage area on another server device (not shown).

  Although the operation unit 4 is not illustrated as a push button type key, the operation unit 4 includes a power key for turning on / off the power, and the control unit 1 performs an input operation output from the operation unit 4 corresponding to the operation key. Perform processing according to the signal. The touch display unit 5 has a configuration in which a touch panel 5b is stacked on a display panel 5a. Although the imaging unit 6 constitutes an image reading function and is not shown in the drawing, the imaging unit 6 is a digital that can photograph a subject with high definition by forming a subject image from an optical lens on an imaging element (CCD, CMOS, etc.). The camera unit includes a photographing lens, an image sensor, various sensors, an analog processing unit, a digital processing unit, and the like. A wireless LAN (Local Area Network) communication unit 7 is a wireless communication module capable of high-speed and large-capacity communication, and can be connected to the Internet via a nearby wireless LAN router (not shown).

FIG. 2 is an external perspective view of the information reading apparatus showing a state when a paper medium is read by the information reading apparatus.
The information reading device has a configuration in which a tablet device 11 and a paper medium 12 are mounted on a double-open binder 10 and is basically synonymous with the tablet device 11. The binder 10 has a configuration in which the first casing 10a and the second casing 10b are attached so as to be openable and closable through a hinge portion 10c so that the first casing 10a and the second casing 10b can be opened and closed. The body 10b can be opened and closed from a state in which the body 10b is opened to a state in which the second housing 10b overlaps the first housing 10a (a state in which it is completely closed). The touch display unit 5 and the imaging unit 6 of the tablet device 11 are disposed so as to be positioned on the surface side of the tablet device 11, and the imaging unit 6 further includes one end central portion on the surface side (in the illustrated example, the central portion on the left end of the surface). ).

  When the angle between the first housing 10a and the second housing 10b falls within a predetermined angle range, the tablet device 11 captures the entire paper medium 12 placed on the first housing 10a. The acquired image is acquired as a read image. For example, in a state where the first casing 10a is placed on a desk surface or the like, an angle when the second casing 10b rises diagonally, that is, a rising angle of the second casing 10b is a predetermined angle. When the angle range is reached, that is, when the optimum angle suitable for photographing the paper medium 12 is, for example, 70 °, photographing is performed at a predetermined angle (for example, ± 5 °) before and after the optimum angle. The paper medium 12 is photographed when the angle range (65 ° to 75 °) is reached.

  Contrary to the case described above, the first housing 10a can be installed to be used obliquely with the second housing 10b placed on a desk or the like. The paper medium 12 indicates a medium on which information for optically reading characters, charts, and the like is described. For example, the paper medium 12 is a notebook, a report paper, a book, or the like, but specifies that the material is paper. In addition, it means a subject on which information is described, and includes electronic paper that can display information electronically.

  FIG. 3 is a diagram for explaining one determination method for determining whether or not the paper medium 12 is a spread page. FIG. 3 (1) shows a state in which a paper medium 12 (hereinafter referred to as a single-sided document material) in which a plurality of sheets are bundled and the upper right corner thereof is fastened with a clip or the like is being paged. It is the figure which showed the state. In the live view image obtained by photographing the state in which the single-ended document material with one corner of the sheet being fastened is being paged in this way, the image changes during page turning in the vertical direction and the right direction. It appears greatly. That is, as shown in FIG. 3 (2), an image change area b in which a part of the image (the page that has been turned) protrudes from the paper area a of the document material is a vertical direction in the figure. And the right direction is larger.

  FIG. 3 (3) is a diagram illustrating a state in which a two-page spread type document material such as a notebook is being turned as the paper medium 12. As shown in FIG. 3 (4), in the live view image obtained by photographing the state in which the spread type document material is paged, a part of the image (に よ り) The image change area b protruding from the page) is almost not in the left-right direction but slightly larger in the up-down direction. Therefore, in the present embodiment, the change in the image at the time of turning the page differs depending on the document format (single-fixed document or spread-type document), and the change in the right direction of the paper area a becomes remarkable. Therefore, whether or not the image change area b protrudes to the right side of the paper area a is used as a document format determination criterion.

  FIG. 4 is a diagram for explaining another determination method for determining whether or not the paper medium 12 is a spread page. FIG. 4 (1) is a diagram showing a state in the middle of page turning of the one-sided document material, as in FIG. 3 (1). In this way, in the Live View image that captures a state where the single-ended document material is being paged, the change in the image at the time of page turning is obliquely higher in the document content of the next page (back page). Appears as a change in direction (arrow direction in the figure). FIG. 4 (2) is a diagram showing a state in which a spread type document material is being paged, as in FIG. 3 (3). In the Live View image that captures a state in which the spread type document material is being paged in this way, the change in the image at the time of page turning is due to the change in the document content on the next page (subsequent page) Appears as a change in the direction of the arrow in the figure. Therefore, in the present embodiment, since the change direction of the document content of the next page (subsequent page) at the time of page turning differs according to the document format, the change direction of the document content is used as the determination criterion of the document format.

  FIG. 5 is a diagram for explaining still another method for determining whether or not the paper medium 12 is a spread page. FIG. 5 (1) is a diagram showing a state at the start of page turning in a one-sided document material. In this way, in the Live View image taken at the start of page turning of a single-ended document material, the entire page is slightly bent, bent, or shifted due to page turning. The image change area b is substantially the same as the paper area a of the document material (area surrounded by a broken line in the figure). FIG. 5B is a diagram illustrating a state when page turning is started for a spread-type document material. In this way, in the Live View image that was taken at the start of page turning of a two-page spread document document, when the left page of the double-page spread starts to bend, the entire page is slightly curved, bent, or shifted. The image change area b in which the document content changes because such a change does not occur is a left half area (area surrounded by a broken line in the figure) with respect to the paper area a of the document material. Become. Therefore, in the present embodiment, since the size of the image change area b whose document content has changed at the start of page turning differs from the paper area a according to the document format, the size of the image change area b is set to be different. This is a document format criterion.

  As described above, in the present embodiment, the control unit 1 performs a plurality of determination methods, that is, a method for determining whether the image change area b protrudes to the right side of the paper area a, the next page at the time of page turning (back page) ) In accordance with whether the change direction of the document content is the right lateral direction, or in accordance with a method of determining whether the image change area b is the left half of the paper area a. However, at that time, it is determined whether or not the page is a spread page by sequentially performing a determination according to a plurality of determination methods according to a predetermined priority order.

  Next, the operation concept of the information reading apparatus in the present embodiment will be described with reference to the flowcharts shown in FIGS. Here, each function described in these flowcharts is stored in the form of a readable program code, and operations according to the program code are sequentially executed. Further, it is possible to sequentially execute the operation according to the above-described program code transmitted via a transmission medium such as a network. In other words, in addition to the recording medium, an operation unique to the present embodiment can be executed using a program / data supplied externally via a transmission medium. 6 and 7 are flowcharts showing an outline of the operation of the characteristic part of the present embodiment in the overall operation of the information reading apparatus. When the flow of FIG. 6 and FIG. Return to the main flow of operation (not shown).

FIG. 6 is a flowchart for explaining an operation (characteristic operation of the present embodiment) that is started when a document page turning shooting mode is designated in response to switching of an operation mode by a user operation.
First, the control unit 1 activates the imaging unit 6 in response to switching to the document page turning shooting mode to start a shooting operation (step A1), acquires the captured image from the imaging unit 6 and obtains the captured image from the work memory 3b. Is temporarily stored (step A2). The photographed image is acquired as a preview (live view) image (step A3), and the preview image is analyzed to detect a contrast ratio and detect a rectangular area while detecting a rectangular area. Is specified (step A4).

  Further, a preview image is further acquired from the imaging unit 6 (step A5), and a comparison is made between the preview image acquired last time and the preview image acquired this time (step A6) to check whether there is a change in the image contents. (Step A7) When a change in the image is detected (YES in Step A7), it is determined that the page is turned and the contents of the change are temporarily stored in the work memory 3b (Step A8). Next, it is checked whether the document page turning shooting mode has been canceled and the end of shooting has been instructed (step A9). If the document page turning shooting mode is still set (NO in step A9), step A5 described above is performed. Returning to step S5, a preview image is acquired from the imaging unit 6, and thereafter, every time a change in the image is detected (until the page turning ends), the operation of temporarily storing the change contents is repeated (steps A5 to A8).

  If no change in the image is detected (NO in step A7), it is determined that the page turning has ended, the process proceeds to step A10, and the captured image temporarily stored in the work memory 3b is used as the previous captured image. And the preview image acquired this time is compared with the previous captured image to check whether there is a change in the image content (step A11). If there is no change in the image content (NO in step A11), it is determined that the image is not changed due to page turning, the process proceeds to step A13, and the change content temporarily stored in the work memory 3b is cleared. Then, the process returns to step A9 for determining whether to cancel the document page turning shooting mode. On the other hand, when a change in the image content is detected as a result of comparing the preview image acquired this time with the previous photographed image (YES in step A11), it is determined that the image has changed due to page turning, and the document format is changed. Then, the process proceeds to the process of saving the page image (step A12). Then, after performing the process (step A13) which clears the change content of temporary memory, it returns to step A9 which discriminate | determines cancellation | release of document page turning photography mode.

FIG. 7 is a flowchart for explaining in detail the process of saving the page image according to the document format (step A12 in FIG. 6).
First, the control unit 1 refers to the work memory 3b in which the change contents of the image when the read page is turned are sequentially stored (step B1), and analyzes the change state of the image. As shown in FIGS. 3 (1) and 3 (2), a part of the image (the page being turned) is turned from the right side of the paper region a of the document material by the page turning, and the image change region b is larger than a predetermined threshold. A check is made to see if it is protruding (step B2).

  Here, when the image change area b is larger than the threshold value on the right side of the paper area a and protrudes (YES in step B2), as shown in FIGS. Is recorded and stored as data for one page per image (step B3). Then, after clearing the photographed image temporarily stored in the work memory 3b (step B4), the process goes out of the flow of FIG.

  On the other hand, if the image change area b is large on the right side of the paper area a and does not protrude (NO in step B2), it is determined that there is a possibility that the spread type document material is page-turned, and FIG. ), It is checked whether the change direction of the document content is the right lateral direction (step B5). Here, if the change direction is not the right lateral direction (NO in step B5), it is determined that there is a possibility that the one-sided document material is page-turned, and the change area of the document content is the paper area a. It is checked whether it is the left half area (step B6).

  If the change direction is not right lateral (NO in step B5) and the image change area b is not the left half area of the paper area a (NO in step B6), the one-sided document material is paged. Therefore, the process proceeds to a process of recording and saving the entire photographed image as one page data (step B3). When the direction of change is the right lateral direction (YES in step B5) or when the image change area b is the left half area of the paper area a (YES in step B6), the spread type document material is turned over. It is determined that this is the case, and a process of dividing into left and right pages with the vertical center line of the paper region a as a boundary is performed (step B7). The left and right regions divided in this way are recorded and stored separately as left and right independent pages, for example, a right page and a left page (step B8). Then, after clearing the photographed image temporarily stored in the work memory 3b (step B4), the process goes out of the flow of FIG.

  As described above, in the present embodiment, the control unit 1 analyzes the photographed image obtained by photographing the entire document material as the paper medium (information recording medium) 12 by the imaging unit 6 so that the paper medium 12 is a spread page. It is determined whether or not there is a spread page. If the page is a spread page, the photographed image is divided into each page of the spread page. Therefore, even if the entire paper medium 12 of the spread page is shot once, one image 1 It can be processed as a page, saves the trouble of editing work that divides a captured image of a facing page by user operation, and can efficiently process an image obtained by continuously capturing a book or the like for each page. Become.

  The control unit 1 compares each captured image sequentially captured when turning the page of the paper medium 12, detects a change in the image content, and determines whether the page is a spread page based on the change in the image content. As a result, it is possible to determine whether the page is a facing page from the page turning state.

  The control unit 1 compares the captured images sequentially taken at the time of turning the page, detects a protruding area in the page turning direction of the paper medium 12 as a change in the image content, and spreads the page based on the protruding area. Therefore, it is possible to accurately and stably determine the facing page from the page turning state.

  The control unit 1 determines that the page is a spread page if the size of the protruding area in the page turning direction of the paper medium 12 is equal to or greater than a predetermined value. it can.

  The control unit 1 compares the captured images sequentially taken at the time of page turning, detects a change in the page turning direction as a change in the image content, and determines whether the change is in the page turning direction. Since it is determined whether or not the page is a spread page, the spread page can be accurately and always stably determined from the page turning state.

  The control unit 1 compares the captured images sequentially taken at the time of turning the page, and detects a change in the page content as a change in the page turning, that is, a substantially entire region or a substantially half region of the paper medium 12. Since it is determined whether or not the page is a spread page based on the size of the change area, the spread page can be accurately and always stably determined from the page turning state.

  Since the control unit 1 determines whether or not the page is a spread page by sequentially performing determinations according to a plurality of determination methods according to a predetermined priority order, the page is further accurately determined. be able to.

  Since the control unit 1 divides the photographed image into two left and right pages with a bent portion (vertical center line) L1 between each page with the center as the boundary, the right page and the left page are accurately determined from the spread page. You can get a page.

  In the above-described embodiment, as a plurality of determination methods, a method for determining whether the image change area b protrudes to the right side of the paper area a, or the document content of the next page (back page) at the time of page turning. A method of determining whether the change direction of the image is right lateral direction or a method of determining whether the image change area c is the left half area with respect to the paper area a is exemplified, For example, the determination method shown in FIG. 8 may be used. That is, in the above-described embodiment, whether the page is a facing page is determined from the page turning state, but the form and the bending state are detected by analyzing the photographed image of the paper medium 12, and the detection form is detected. Whether or not the page is a spread page may be determined based on the bending state.

  For example, in the paper medium 12, there is a folded portion (vertical center line) L1 between facing pages, and a horizontal line L2 is symmetric with respect to the folded portion (vertical center line) L1 (paper). It may be determined that the page is a spread page based on the fact that it is a form) and the bending L3 is symmetrical with respect to the bent portion (vertical center line) L1. This makes it possible to determine a spread page without performing page turning.

  In the embodiment described above, when it is determined that the page is a spread page, the photographed image is divided into each page of the spread, but further, the orientation of the paper medium 12 is further determined by analyzing the photographed image. Then, the rotation of the divided page data may be controlled so as to match the direction of the paper medium 12. In this case, the spread-type document is highly likely to be on the paper as shown in FIG. 9A, and the single-sided document in which the upper right corner of the paper is fastened. 9 (2), it is highly possible that the top or right side of the image is on the paper, so that it is possible to determine the document format together with the orientation of the paper. As a result, for example, the overall processing efficiency can be improved compared to a method of determining the orientation of a sheet from the direction of characters using the character recognition function.

  In the above-described embodiment, it is determined whether or not the page is a spread page by sequentially performing determinations according to a plurality of determination methods according to a predetermined priority order. When a method is selected, it may be determined whether the page is a facing page by the determination method. If the determination method can be arbitrarily selected in this way, even individual page turning can be handled, and determination can be made with high accuracy.

  In the embodiment described above, the determination is made according to whether the image change area b protrudes to the right side of the paper area a. However, the determination is made according to whether the image change area b protrudes to the right side and the upper side of the paper area a. It may be.

  In the above-described embodiment, if the image change area b is larger than the threshold value on the right side of the paper area a and does not protrude, it is determined that there is a possibility that the spread type document material is page-turned, and the document content It is checked whether the change direction of the document is right sideways, or whether the change area of the document content is the left half area of the paper area a, but how to combine these determination methods Whether to perform the determination may be arbitrarily changed. Further, when all the conditions in the plurality of determination methods are satisfied, the page may be determined as a spread page. Conversely, when any one of the plurality of determination methods satisfies the condition, the page is determined as a spread page. It may be.

  In the above-described embodiment, the photographed image is divided into left and right pages at the center of the sheet, but may be divided into upper and lower pages at the center of the sheet area. Further, the number of divisions is not limited to two divisions, and may be three divisions as long as it is a page unit.

  In the embodiment described above, a single-fixed document material in which a plurality of sheets are bundled and the upper right corner thereof is fastened with a clip or the like is illustrated, but the position to be fastened with a clip or the like is limited to the upper right corner of the paper. Instead, it may be the upper left corner or the center of the upper end.

  In the above-described embodiment, the photographed image is divided into left and right pages in the center of the paper, and the left and right pages are recorded and stored, respectively, but even in a spread type, only one side is printed or handwritten, When the other side is blank, only the printed / handwritten page may be extracted and recorded and saved, excluding the blank page.

  In the above-described embodiment, the information reading apparatus is configured such that the tablet device 11 and the paper medium 12 are mounted on the double-open binder 10. However, the present invention is not limited thereto, and the paper medium 12 is mounted by attaching an imaging unit to a column or the like. The configuration is arbitrary, such as photographing from an obliquely upward direction.

  In the above-described embodiment, the information reading device is the tablet device 11. However, the information reading device is not limited to this. For example, the information reading device may be a personal computer with a camera, a PDA (personal portable information communication device), a smartphone, or a digital camera itself. May be.

  Further, the “apparatus” and “unit” shown in the above-described embodiments may be separated into a plurality of cases by function, and are not limited to a single case. In addition, each step described in the above-described flowchart is not limited to time-series processing, and a plurality of steps may be processed in parallel or separately.

The embodiment of the present invention has been described above. However, the present invention is not limited to this, and includes the invention described in the claims and the equivalent scope thereof.
