Description

  The present invention relates to an enlarged reading device used as a daily life tool for a visually impaired person such as a low vision person.

  Conventionally, in this type of enlarged reading device, there is an enlarged reading device disclosed in Patent Document 1 below. This magnifier reads out the text area you want to read on the pedestal with the camera located above it, and the image output from this camera is processed to enlarge and display the text area you want to read in the text. It is displayed on the display screen by the device.

Therefore, when using this magnifier reader to read the character area of the reading material enlarged as described above, the visually handicapped person wants to read the enlarged image while moving the reading material little by little by himself / herself. The characters in the character area are read sequentially.
JP 7-234919 A

  However, according to the magnified reader, the character area desired to be read is magnified and displayed as described above. Therefore, even if the pedestal is moved slightly, the display content of the display screen of the display device changes greatly. This is the same even if the reading itself is moved directly, regardless of the frame.

  Therefore, for example, when a line break occurs in a character area to be read of the reading material, and the line break portion is off the display screen of the display device, the visually impaired person does not know how to move the reading material by the gantry, This causes a problem of losing sight of the line feed part.

  Accordingly, an object of the present invention is to provide an enlarged reading device that can sequentially and satisfactorily read a desired portion of the reading material without moving the reading material in order to deal with the above.

In solving the above-mentioned problem, an enlarged reading device according to the present invention, according to the description of claim 1,

And a reference point redisplay processing means (164b) for processing the reference point to be displayed again on the display screen on the display means,
Based on the re-display processing by the reference point re-display means, the display means enlarges and displays a part of the still image on the display screen and re-displays the reference point.
Each time the reference point is redisplayed, the movement processing means moves the at least one subsequent line of the still image from the reading start portion to the reading end portion in the state of being enlarged and displayed on the display screen. It is characterized by the fact that it is processed.

  In this way, when the line including the reading start part is processed to move to the reading end part, and the at least one subsequent line is processed to move similarly to the line including the reading start part. At this time, a part of the still image is enlarged and displayed on the display means on the display means, and the reference point is displayed again.

  Then, every time the reference point is redisplayed, the at least one subsequent line of the still image is moved from the reading start portion to the reading end portion while being enlarged and displayed on the display screen. .

  Therefore, the reader can surely view without losing sight of the beginning of the next line to be read, and can clearly identify the beginning of the line to be read next. Thereby, the line to be read next can be surely read. As a result, the function and effect of the first aspect of the invention can be more specifically improved.

Moreover, according to the description of Claim 3, this invention is the expansion reader according to Claim 1 or 2,
The camera includes storage means (51) for storing a camera ID code, and a USB element (60) for outputting the camera ID code or the electronic image data.

  As shown in FIG. 2, the display device 80 includes a drive circuit 80a and a liquid crystal panel 80b (hereinafter also referred to as an LCD 80b). The drive circuit 80a is controlled by the CPU 77 by the computer 70c and drives the LCD 80b for display.

  In the present embodiment configured as described above, when the magnified reading device is put into an operating state, both the camera C and the personal computer system P are in an operating state. Along with this, in the camera C, the imaging device 40 optically images the two-dimensional imaging target part (see FIG. 6) of the newspaper 20 through the lens 30 and outputs it to the image processing circuit 50 as electronic imaging data. To do.

  Then, the image processing circuit 50 performs image processing on the electronic imaging data to generate electronic image data representing an image of the imaging target part. Hereinafter, the image of the imaging target part is also referred to as a camera image.

  Further, when the personal computer system P is activated as described above, the computer 70c starts executing the computer program according to the flowcharts of FIGS. First, in step 100 of FIG. 3, ID code request processing is performed. In this ID code request processing, the camera ID code is requested by the computer 70c by the CPU 77 through the USB port 79 via the bus line 77a.

  At this stage, if the camera C is not connected to the USB port 79 of the computer 70c via the USB element 60, the camera ID code request from the computer 70c is not input to the camera C. For this reason, there is no input of the camera ID code from the camera C to the computer 70c.

  Therefore, in step 110, it is determined NO because there is no input of the camera ID code. Accordingly, the transition of the computer program to step 111 is prohibited.

  In such a state, it is assumed that the camera C is connected to the USB port 79 of the computer 70c by the USB element 60. Then, along with the ID code request processing in step 100, a camera ID code request from the computer 70 c is input by the CPU 77 to the image processing circuit 50 of the camera C through the bus line 77 a, USB port 79 and USB element 60.

  Therefore, the image processing circuit 50 reads the camera ID code from the memory 51 and inputs it from the USB element 60 to the CPU 77 of the computer 70c through the USB port 79 and the bus line 77a. Accordingly, the computer 70c determines YES in step 110 by the CPU 77, and in step 111, inputs the camera ID code from the USB element 60 to the RAM 78b through the bus line 77a and temporarily stores it.

  Thereafter, in step 120, it is determined whether or not the ID codes match. If the camera ID code stored in the RAM 78b as described above matches the personal computer system ID code, the determination in step 120 is YES.

  In the present embodiment, the personal computer system ID code described above identifies the personal computer system P and is stored in advance in the ROM 78a of the computer 70c. Therefore, in the determination in step 120, it is determined whether or not the camera ID code stored in the RAM 78b matches the personal computer system ID code read from the ROM 78a.

  Here, if the camera ID code stored in the RAM 78b does not match the personal computer system ID code read from the ROM 78a, the camera C is not a camera to be properly connected to the personal computer system P. Therefore, the determination in step 120 is NO, and the transition of the computer program to step 130 and subsequent steps is prohibited.

  Thus, if the camera C is not a camera that can be legitimately connected to the personal computer system P, even if the camera C is connected to the personal computer system P, the original enlarged reading function as an enlarged reading device is invalidated.

  On the other hand, if the camera ID code stored in the RAM 78b matches the personal computer system ID code read from the ROM 78a, the camera C is a camera to be properly connected to the personal computer system P.

  Thereby, only when the camera C is a camera that can be legitimately connected to the personal computer system P, the camera C is connected to the personal computer system P, and the original enlarged reading function as the enlarged reading device becomes effective.

  Therefore, if the camera ID code matches the personal computer system ID code as described above, the determination in step 120 is YES, and the transition of the computer program to step 130 and later is permitted.

  As described above, when the determination in step 120 is YES, it is determined in the next step 130 whether or not the moving image key has been operated. At this stage, if the moving image key 71a of the operating device 70b is operated, YES is determined in step 130, and the computer program proceeds to the moving image processing routine 140.

  In the moving image processing routine 140, the electronic image data from the image processing circuit 50 is taken in by the CPU 77 into the computer 70c through the USB element 60, the USB port 79 and the bus line 77a. The electronic image data captured in this way is corrected so as to be as easily viewable as possible by the reader by operating the black and white reversal key 76a and the gamma correction key 76b of the operation device 70b, and is displayed as data representing a corrected camera image. Is output.

  Accordingly, in the display device 80, the LCD 80b is driven by the drive circuit 80a to display the corrected camera image on the display screen. Here, when the reader moves the newspaper 20 in order to specify the imaging target part at the time of imaging by the imaging element 40, the imaging target part is imaged by the imaging element 40 as a moving image. Therefore, as described above, the image displayed on the display screen of the LCD 80b is a moving image that can be recognized for the time being even if the camera image is not clear.

  In such a stage, when the still image key 71b of the operating device 70b is operated, NO is determined in step 130, and then YES is determined in step 150. Accordingly, in step 151, the corrected camera image is stored. In this storage processing, data representing the corrected camera image in the moving image mode processing routine 140 is input to the RAM 78b and temporarily stored. This means that the corrected camera image is stored in the RAM 78b as data representing a still image (hereinafter referred to as still image data).

  When the corrected camera image is stored in the RAM 78b as still image data in this manner, a still image display process is performed in step 152. In this still image display process, still image data stored in the RAM 78 b is output to the display device 80 in step 151. Accordingly, the LCD 80b of the display device 80 is driven by the drive circuit 80a based on the still image data, and displays the still image on the display screen. This still image is displayed as an image as shown in FIG.

  When the processing in step 152 ends as described above, the processing of the still image mode processing routine 160 is performed (see FIGS. 3 to 5). First, in step 161 of FIG. 4, it is determined whether or not the magnification adjustment key 73 of the operating device 70b is operated.

  If the determination in step 161 is YES, it is determined in step 162 whether or not the enlargement magnification has been selected. Here, if the magnification adjustment key 73 is in the middle of adjusting the enlargement magnification by the repeated operation of the enlargement key portion or the reduction key portion, it is determined NO in step 162. At this time, it is assumed that the window W1 surrounding the character area A1 to be enlarged among the still images displayed on the display screen of the LCD 80b is at the position shown in FIG. The position of the window W1 in the display screen is adjusted by operating the scroll key 72 of the operating device 70b.

  In the state as described above, when the operation of the magnification adjustment key 73 is finished, the selection of the enlargement magnification is finished, so that it is determined as YES in Step 162. Along with this, in the next step 162a, the setting process of the selection magnification is performed. Accordingly, the enlargement magnification selected as described above is input to the RAM 78b and temporarily stored. This means that the above-described selective enlargement magnification has been set.

  Thereafter, in step 162b, a part of the still image is enlarged and displayed. In this enlargement display processing, the data portion corresponding to the character area A1 (corresponding to a part of the still image) among the still image data stored in the RAM 78b is enlarged based on the set enlargement magnification, and the enlarged data is displayed. Output to the display device 80 as a unit.

  Accordingly, in the display device 80, the LCD 80b is driven by the drive circuit 80a based on the enlarged data portion, and as shown in FIG. 8, the character area A1 is changed to the character area A2 (hereinafter also referred to as the enlarged character area A2). Display). That is, the character area A2 is enlarged at the set enlargement magnification and displayed over almost the entire display screen of the LCD 80b as shown in FIG. In accordance with this, the window W1 is similarly enlarged and displayed in the window W2 (hereinafter also referred to as an enlarged window W2).

  As described above, when the enlarged display processing of a part of the still image in step 162b is completed, the reading start portion determination processing is performed in step 162c. In the reading start portion determination process, the cursor position on the display screen of the LCD 80b is moved to the reader's desired position by operating the keyboard 70a. At the present stage, the reader's desired position is assumed to be in the upper right corner of the character “view” (see FIG. 8) in the enlarged character area A2.

  Thus, when such an operation of the keyboard 70a is completed, the reading start portion is determined, so that it is determined as YES in Step 163.

  Next, in step 164 of FIG. 5, it is determined whether or not a reference point on the display screen of the LCD 80b has been determined. Here, if the reference point key 74 of the operating device 70b is operated, the current position of the cursor on the display screen of the LCD 80b is determined on the display screen as a reference point. Determined.

  If the determination in step 164 is YES as described above, a reference point storage process is performed in step 164a. In this reference point storage process, the computer 70c causes the CPU 77 to use the RAM 78b as the data representing the reference point (hereinafter also referred to as reference point data) using the upper right corner of the character “view” in the enlarged character area A2 described above. Memorize temporarily.

  Next, in step 164b, a reference point display process is performed. In this reference point display process, an asterisk mark “*” is created and output to the display device 80 as asterisk mark display data for specifying the upper right corner of the character “view” in the above-described enlarged character region A2.

  Accordingly, in the display device 80, the LCD 80b is driven by the drive circuit 80a based on the asterisk mark display data, and the upper right corner of the character “view” in the enlarged character area A2 described above is displayed on the display screen. An asterisk mark “*” (see S in FIG. 9) is displayed.

  Thus, the reader can clearly see the reading start portion of the enlarged character area A2 on the display screen of the LCD 80b with the display of the asterisk mark S as described above. As a result, the reader can surely start reading the enlarged character area A2 (see FIG. 9) of the newspaper 20 from the characters “view”.

  Thus, if the scroll key 72 is used to perform a scroll operation along the display screen of the LCD 80b without operating the return key 75, the process of circulating both steps 165 and 166 is repeated. In such a state, the reader sequentially reads the imaging target portion (see FIG. 6) of the newspaper 20 from the character “view” in the enlarged character area A2 described above downward.

  Specifically, the character area displayed in the enlarged window W2 on the display screen of FIG. 9 in accordance with the scroll operation is the corrected still image (corresponding to the imaging target portion of the newspaper 20 (see FIG. 6)). Of the enlarged character area A2. Accordingly, the characters in the character area displayed in the enlarged window W2 are sequentially read downward while changing in this way. Here, the second line from the right in FIG. 6 is sequentially read from the characters “view” to the characters “stage” in the enlarged window W2 in FIG.

  Thus, when the second line from the right in FIG. 6 has been read, the character area A3 shown in FIG. 10 is displayed in the enlarged window W2 in the display screen of the LCD 80b.

  Therefore, when the reader operates the return key 75, YES is determined in step 166, and thereafter, a reference point redisplay process is performed in step 166a. In this reference point redisplay process, the upper right corner of the character “view” in the enlarged character area A2 is stored as reference point data in the RAM 78b in step 164a (see FIG. 5) as described above. Based on the point data, the display content in the enlarged window W2 is returned from the enlarged character area A3 to the display contents of the asterisk mark S and the enlarged character area A2.

  Therefore, the LCD 80b displays the enlarged character area A2 and the asterisk mark S (see FIG. 9) for specifying the reference point again on the display screen. Accordingly, the computer program returns to step 165.

  In such a stage, if the scroll key 72 is used for scrolling along the display screen of the LCD 80b without operating the return key 75, the process of circulating both steps 165 and 166 is repeated as described above.

  In such a state, the character region displayed in the enlarged window W2 on the display screen of FIG. 9 in accordance with the scroll operation is displayed on the corrected still image (the imaging target portion of the newspaper 20 (see FIG. 6)). Of the enlarged character area A2.

  Accordingly, the reader faces the imaging target portion (see FIG. 6) of the newspaper 20 downward from the character “no” (see FIG. 9) to the left of the character “view” in the enlarged character area A2 described above. Read sequentially. Specifically, in the same manner as described above, the third line from the right in FIG. 6 is sequentially read in the enlarged window W2 in FIG. 9 from the characters “no” to the characters “hear”. .

  When the third line from the right in FIG. 6 has been read as described above, the character area A3 shown in FIG. 10 is displayed in the enlarged window W2 in the display screen of the LCD 80b.

  Therefore, when the reader operates the return key 75 again, YES is determined in step 166, and in the reference point redisplay process in step 166a, the enlarged window W2 is based on the reference point data stored in the RAM 78b as described above. The display content is returned from the enlarged character area A3 to the display content including the asterisk mark S and the enlarged character area A2.

  Therefore, the LCD 80b displays the enlarged character area A2 and the asterisk mark S (see FIG. 9) for specifying the reference point again on the display screen. Accordingly, the computer program returns to step 165 again.

  In such a stage, if the scroll key 72 is used for scrolling along the display screen of the LCD 80b without operating the return key 75, the process of circulating both steps 165 and 166 is repeated as described above.

  In such a state, the character area displayed in the enlarged window W2 on the display screen of FIG. 9 is displayed on the display screen of FIG. Corresponding to (see FIG. 6)) and changes to a portion below the enlarged character area A2.

  Accordingly, the reader faces the imaging target portion (see FIG. 6) of the newspaper 20 downward from the character “·” (see FIG. 9) to the left of the character “no” in the enlarged character area A2 described above. Read sequentially. Specifically, in the same manner as described above, the fourth line from the right in FIG. 6 is sequentially read in the enlarged window W2 in FIG. 9 from the character “·” to the character “O”. .

  When the fourth line from the right in FIG. 6 has been read in this way, the character area A3 shown in FIG. 10 is displayed in the enlarged window W2 in the display screen of the LCD 80b as described above. .

  As described above, when the reader finishes reading the fourth line from the right in FIG. 6, when the reader operates the return key 75 again, YES is determined in step 166, and the reference point redisplay processing in step 166a Similarly, based on the reference point data stored in the RAM 78b, the display content in the enlarged window W2 is returned from the enlarged character area A3 to the display content including the asterisk mark S and the enlarged character area A2.

  Therefore, the LCD 80b displays the enlarged character area A2 and the asterisk mark S (see FIG. 9) for specifying the reference point again on the display screen. Accordingly, the computer program returns to step 165 again.

  However, at such a stage, even if the asterisk mark S is displayed in the enlarged window W2, no character area other than the enlarged character area A2 is displayed. Accordingly, there is no line to be read next in the enlarged character area A2.

  Therefore, if the scroll key 72 is scrolled to the right by the scroll key 72 along the display screen of the LCD 80b without the operation of the return key 75 during the determination of NO in step 165, both steps 165, The process of circulating through 166 is performed, and the enlarged character area displayed in the enlarged window W2 of the display screen of the LCD 80b is moved to the right by one line. Accordingly, the enlarged character area in the enlarged window W2 becomes an enlarged character area A4 as shown in FIG.

  After that, if the scroll key 72 is used to scroll along the display screen of the LCD 80b without operating the return key 75, the process of circulating both steps 165 and 166 is repeated and the enlarged window is displayed on the display screen of FIG. The character area A4 displayed in W2 changes to a part below the enlarged character area A4 in the corrected still image (corresponding to the imaging target part (see FIG. 6) of the newspaper 20). Accordingly, in substantially the same manner as described above, the reader reads the line starting from the character “Bi” in the enlarged character area A4 described above in the above-described imaging target portion (see FIG. 6) of the newspaper 20 in substantially the same manner as described above. Then read sequentially.

  Thus, when the fifth line from the right in FIG. 6 has been read, the character area A5 shown in FIG. 12 is displayed in the enlarged window W2 in the display screen of the LCD 80b. Thereafter, the sixth and subsequent lines from the right in FIG. 6 are sequentially read by the processing substantially similar to the above.

  As described above, in this embodiment, the enlarged reader is configured with the camera C and the personal computer system P each having the above-described configuration.

  With such a configuration, the line including the character “view” at the start of reading specified by the asterisk mark S in the enlarged character area displayed on the display screen of the LCD 80 b under the scroll operation by the scroll key 72. When reading (corresponding to the second line from the right in FIG. 6) is completed, and the line adjacent to the left of the line including the character “view” at the beginning of the reading (in FIG. 9), the display content of the display screen of the LCD 80b is returned to the display content of FIG. 9 by operating the return key 75, respectively.

  Therefore, the reader can surely view without losing sight of the beginning of the next line to be read, and can clearly identify the beginning of the line to be read next. This means that the next line to be read is specified by automatic line feed. Thereby, the line to be read next can be surely read.

  Further, as described above, when the display content of the display screen of the LCD 80b becomes the display content of FIG. 9 by completing the reading from the right to the fourth line in FIG. 6, the portion to be read next is displayed on the display screen of the LCD 80b. Even if not, by moving the display content of the display screen to the right by the scroll operation as described above, the portion to be read next is enlarged and displayed on the display screen of the LCD 80b. As a result, the sixth and subsequent lines from the right in FIG. 6 can be read.

  In this embodiment, the portion of the newspaper 20 to be read is not directly read in an optically enlarged state, but is displayed on the display screen of the LCD 80b using the electronic image data captured from the camera C as described above. Since the portion to be read of the newspaper 20 is read with the enlarged still image, even if the enlargement magnification is large, the reading can be continuously performed without moving the reading material regardless of this. Moreover, since the reading material can be read without moving in this way, a frame and a table for moving the reading material are also unnecessary. Therefore, the enlarged reading device is further reduced in weight.

  Further, since the portion to be read of the reading material enlarged and displayed on the display screen of the LCD 80b is read using the electronic image data captured from the camera C as described above, the newspaper 20 is not necessary for reading. Therefore, the lighting conditions of the newspaper 20 are not bothered.

  On the other hand, if the magnification adjustment key 73 is not operated in step 161 of FIG. 4 described above, it is determined NO in step 161, and the current still image display process is performed in step 161a. In this display process, the still image displayed in the still image display process in step 152 is displayed on the display screen of the LCD 80b in the same manner as described above.

  Thereafter, the still image displayed on the display screen of the LCD 80b is made after the enlargement display processing of a part of the still image in the above-described step 162b except that the still image is not enlarged unlike the processing in the step 162b. The same processing as the processing after step 162c is performed in the processing after step 162c after the current still image display processing at step 161a. Also in this way, it is possible to sequentially read the imaging target portions (see FIG. 6) of the newspaper 20 in substantially the same manner as described above.
